Xometry FAQs

You will see three production speed options with every CAD file you upload to fit your budget and deadlines: Expedite, Standard, and Economy.

What does Expedite mean?

Expedite is the fastest production speed and delivery date option which includes an expedite fee. Your parts are made by our US Partner Network.

What does Standard mean?

Standard is the base Xometry price and lead time offering which means that Standard provides a price and lead time that does not include an expedite fee for shorter lead times or a price reduction and longer lead times and/or overseas manufacturing. Your parts are made by our US Partner Network. We are working to further improve pricing and shorten lead times in this option.

What does Economy mean?

Economy gives you the lowest possible cost. With this option, your parts may be made overseas and take longer to arrive. We will identify if your parts will be made overseas on the quote platform.

How do I know if my part is being made in China?

We list the country of origin on the quote. You can find it here:

Xometry Manufacturing Standards

When I click on production speed, why do all of my parts change to that production speed?

Production speed is an order-level selection. In other words, if you choose Expedite, all of the parts in your quote will be expedited.

What shipping speed do you assume for each production option?

We assume 1-day shipping for Expedite orders and 2-day shipping for Standard and Economy orders. You can always change your shipping method on the checkout page.

Why is Expedite disabled in some cases?

In some cases, we cannot make parts any faster than our Standard option. Therefore, we do not offer an expedite option.

Why is Economy disabled in some cases?

In some cases, we cannot make parts less expensive than our Standard option. Additionally, some manufacturing processes, materials, features, and certifications are not eligible for Economy.

Why can the Expedite price match the Standard price?

If some parts in a quote can be made faster, we will show Expedite prices for all parts in that quote. For parts that we cannot make any faster, you will see Expedite prices that match our Standard price.

How will ITAR or Domestic manufacturing requirements be handled?

Jobs with ITAR and domestic manufacturing requirements will continue to be manufactured by qualified partners in our US Partner Network. Manufacturing in China is not available for ITAR quotes/orders or quotes/orders with DFARS or Domestic requirements.

Will I get finishing certs if my parts are made in China?

No. Xometry does not provide finishing certs for parts that are made in China.

What are the shipping options for Economy?

You can choose from a selection of Ground, 2-day, or Next-day shipping options.

Is there a quality difference in parts that are made in the US vs parts that are made in China?

No. All Xometry parts will meet the regardless of country of origin. All parts will ship back to Xometry for our in-house quality inspection.

Does Xometry collect duties and tariffs?

Yes. Duties and tariffs are included in your part price. You are not required to pay any additional fees.

Does Xometry inspect parts from China?

Yes. All parts that are made in China will go through a Xometry in-house quality inspection before being shipped to the customer.

FDM Design Guide

Infill is a characteristic unique to the FDM process. In FDM an extruder nozzle deposits material along the toolpath, fusing it to previous layers in order to build a 3 dimensional body. Thus being called Fused Deposition Modeling.

In this process the exterior surface is printed with a number of contour paths to ensure dimensionality. The interior of the volume can be printed “solid” but does not necessarily have to be.

The pattern printed inside the contours is referred to as “infill”.

Types of Infill

While there are a theoretically infinite number of infill configurations, we offer three standard infills which provide options for balancing weight, strength, and cost.

Solid infill

Highest strength, closest to full density. This is equivalent toStratasys solid build style.

Method: The extruder deposits alternating diagonal patterns such that the deposition lines connect and press together, creating a near-solid.

Light infill

Weight reduction with some strength reduction. This infill isequivalent to Stratasys Sparse Double Dense build style.**Note: Light infill may trap liquid in the air-gaps. This is due to liquid immersion during support removal, and each column having a potential to be watertight. Ultra-light infill is recommended on parts with large internal volumes.**

Method: A grid pattern is deposited every layer.

Ultra-light infill

For form retention, when the strength of the part isn’t an issue. This infill isequivalent to Stratasys Sparse build style.

Method: A diagonal lined infill pattern. Direction alternates layer by layer, creating an ultra-light grid infill.

Common questions

What percent infill is this?

The final percent infill by volume will vary based on the geometry of the parts. Every part will have a set number of “cap” layers on the top and bottom (default 4) as well as 2-3 contour layers based on part size. Because of this, the surface area to volume ratio will cause the total density of the part to vary.

A thin flat plate may be 100\% filled despite having ultra-light infill selected, if it is thinner than the sum of the top and bottom cap layers.

A large cube may have a very low density, due to the high volume to surface area ratio.

Because of this, the percent density of parts varies to a great degree based on part geometry.

For example:

Solid is 100\% density, right?

Not exactly. There may be some very small voids in between layers where the infill lines meet, but the part will behave as a solid part does. As a result, FDM will not be water-tight as built.

Carbon DLS

Standard

Parts built with Carbon DLS technology will typically have a matte to semi-gloss surface finish depending on feature direction. Parts are cleaned and stripped of supports after build. Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.

Custom

Xometry can provide additional processing to meet your needs. For examples of our additional finishes, please refer to the Carbon DLS section of our photo gallery.

DMLS

Standard

In addition to the removal of support structures, the part surface is media blasted to provide a uniform finish.

Custom

Additional DMLS post-processing, such as CNC Machining of features and polishing, are evaluated on a case-by-case basis. For examples of our additional finishes, please refer to the DMLS section of our photo gallery.

FDM

Standard

FDM parts are built with support material that is removed during post-processing. The part surfaces are left with fine layer lines.

Custom

Xometry can provide additional processing (i.e. painting or sanding) to meet your needs. For examples of our additional finishes, please refer to the FDM section of our photo gallery.

HP Multi Jet Fusion

Standard

HP Multi Jet Fusion parts are de-powdered with a grit blasting process, followed by detailed manual de-powdering for more complex geometries. These parts are left with a surface finish comparable to a sugar cube and a distinct grey color. Natural grey color may be inconsistent depending on feature size and build orientation.

Dyed Black

Parts go through the standard de-powdering process and are then in a heated dye solution. Dyed parts will have a consistent matte black look and are highly recommended for production consistency.

Custom

Xometry provides additional HP Multi Jet Fusion finishing options, including but not limited to: sanding, painting, and plating to meet your needs.

PolyJet

Standard

Support material is removed and parts are cleaned.

Custom

Xometry can provide additional processing and finishes, such as sanding, to meet your needs. For examples of our additional finishes, please refer to the PolyJet section of our photo gallery.

SLA

Strip and ship

SLA parts are cleaned, UV post cured, and stripped of supports. Supported areas will show small grid-like dots or surface blemishes as a result of support removal.

Natural (comparison)

SLA parts are cleaned, UV post cured and stripped of supports. Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper for improved surface quality. Sanding scratches will be visible on supported surfaces.

Natural finish - Built horizontal - Large flat surface was supported

photo gallery

Natural finish - Built vertical - Edge is supported

(Support dots were left intact to easier identify supported surface.)

Matte(recommended)

SLA parts are cleaned, UV post cured and stripped of supports. Supported surfaces will be lightly sanded with 220 or 320 grit sandpaper, then media blasted for a uniform matte finish.

Custom

Xometry provides additional SLA finishing options, including but not limited to sanding, polishing, painting, post thermal processing. For examples of our additional materials, please refer to the SLA section of our photo gallery.

Custom Finish Example - Quick Clear - Only supported surfaces are sanded. Parts will still have visible layering. Quick dry clear coat is applied to enhance natural clarity.

SLS

Standard

SLS parts are de-powdered with a sandblasting process, followed by detailed manual de-powdering for more complex geometries. These parts are left with a surface finish comparable to a sugar cube.

Media Tumbled

Parts go through the standard de-powdering process and are then media tumbled for several hours. These parts will have reduced grow lines and sharp edges may be softened by the tumbling process. The parts are left with an eggshell finish.

Dying

Standard nylon 12 dyed in the specified color. Dye penetrates 0.25 mm of part's surface.

Nickel Plating

Parts are plated with ~0.1 mm / 0.004 in nickel. Plating increases part strength, stiffness, and environmental resistance.

Sanding

In addition to the standard finishing, the grow lines from the manufacturing process are sanded smooth to the touch on surfaces that can be reached.

Custom

Xometry provides additional SLS finishing options, including but not limited to: color dyeing, sanding, painting and plating to meet your needs. For examples of our additional finishes, please refer to the SLS section of our.

Manufacturing Capabilities

Xometry is a model-based company but there are times when a drawing may supersede what is derived from the CAD model. We put together a matrix to help you understand which file and which information we use as the source of truth to manufacture your parts. Unless you specify a requirement in the notes field of the Xometry Instant Quoting Engine all requirements will be derived from either the CAD file, the drawing, or the quote itself.

Let's take a look at a hypothetical scenario. You may have specified Aluminum 6061 on your quote but your drawing may have specified 304 Stainless Steel. Our partners will make your part per theQuotematerial (Al 6061) and not the material in theDrawing(304 SS) per this matrix. So, don't forget to double-check your quote before placing your order.

The Give $20 / Get $20 campaign is no longer active. Please refer to the Xometry Referral Program at https://pages.xometry.com/refer.

As a member of our world-class Manufacturing Partner Network, you are a crucial part of the Xometry customer experience.

Watch our video on FDM 3D Printing:

Xometry offers Fused Deposition Modeling (FDM) which is a 3D printing technology that builds parts out of several types of thermoplastic materials. FDM works by melting a filament of plastic and extruding it on a build platform, zig-zagging back and forth, building the shape of the part layer-by-layer. This process is great for mechanical components which may typically be machined. Material selections include ABS, ASA, Polycarbonate, PC-ABS, PPSF, and ULTEM.

Here are the basic tolerances:

+/- 0.004" or +/- 0.002" per inch, whichever is greater. Build area upto 24 x 36 x 36"

FDM works well for mechanical geometries, larger parts, and parts which may not require ultra-fine features. Very narrow pegs and lips may not resolve due to the bead thickness deposited. We recommend minimum feature size, including text features, to be at least 0.035"(0.045"is safest). FDM prints in 0.010" layers (254 um), 0.013" layers (330 um) on parts over 16" max dimension.

One thing to note is that contoured surfaces and slopes built in the Z-direction will have visible "stair stepping" so if a part is more organic, or has very fine features, you may want to look at other processes such as SLS and PolyJet.

To learn more about FDM, check out Xometry's FDM Design Guide.

Check out our 3D Printed Surface Finishes Gallery to see how it looks!

Once your order has shipped, you will receive a shipping confirmation email that will show the shipping address, the packing list, and tracking number. If an order is shipped on your shipping account, no tracking number will be shown but can be retrieved by our team.

If you are unable to obtain your tracking number through your shipping account, please email [email protected] and we'll be happy to assist you.

Production time varies by technology. When getting a quote, you can find the “Estimated Lead Time” in the quote summary header. This is our standard expected turnaround. Whenever possible, we try to beat that timing if we can.

Xometry offers a 3D printed sample parts kit available for purchase on the Sample Parts Store.

Xometry has seven different 3D printing processes available for instant online quoting. Of these, there are dozens of materials to choose from. Xometry has some excellent references such as its online photo gallery of 3D printed materials, X-Tiles video series, and free design guides to learn more about 3D printing services. But sometimes it makes sense to have some samples on-hand to make better decisions on process and material selections.

This is why Xometry has created a 3D Printing Sample Cube that shows off some of the most popular 3D printed polymers and 5 unique additive manufacturing processes. The cube consists of polypanel-compatible squares that can connect together to form a cube, as well as easily separate. We designed these for future expansion packs (coming soon!) to grow your material collection over time.

Watch our video on Urethane Casting:

Urethane Casting is a process of printing a “master pattern” using PJ3D or SLA to create a mold of silicone gel, which will then be used to cast identical parts using a urethane.Parts manufactured with this process require tooling, a master pattern, and the urethane part material.

Ordering Urethane-Casted parts?

After uploading your 3D CAD file to our instant quoting page, we factor in all the tooling, master pattern, and Urethane Cast parts into the final cost of the total quote. Low quantities are primarily a tooling and pattern fee where larger quantities have those fixed costs amortized among the lot.

Urethane cast parts typically ship in 2-4 weeks with first articles often available earlier.

Tolerances for Urethane Casting

We can offer urethane casted parts as large as 30” long.

Our typical tolerance on Urethanes is +/- 0.010" + 0.003" per inch. Irregular or overly-thick geometries may cause deviances to normal tolerances due to shrinkage.

A shrinkage rate of +0.15\% can be expected due to thermal expansion of the liquid, and the response of the flexible mold.

Possible Finishes

Urethane-Casted parts can be either rigid, flexible, or even rubber-like depending on the composition of the Urethane used. We offer Urethane in a wide variety of color options such as: transparent (standard), black, and color matching. Parts may also be applied with a standard, smooth finish, or a custom finish, which includes adding hardware installations and painting.

How it’s made!

First a master pattern is printed in either PolyJet 3D (PJ3D) or Stereolithography (SLA) to provide an accurate silicone mold. Sometimes tape is placed on flat surfaces to allow for crisp, clean removal of the cast part during post-processing.

Next, the master pattern is encased in liquid silicone to form an accurate mold. After the mold cures it is cut into distinct halves and the pattern is removed. This cavity is used for casting the end product.

A photo of the split pattern. Note that features that may fatigue, such as through holes, are replaced with dowels.

Once the mold tool is created our production will use urethane and other resins to fill the voids. The material will cure and be removed from the tool. This process repeats until the project is finished!

Urethane parts have great end-use applications and can often bring a project to its next level for end-user testing or short run production.

You’ll need a 3D CAD file to get started.If you already have the 3D CAD generated you can upload it through our "Get a Quote" site.Unfortunately, we don’t do 3D scanning, reverse engineering, or design services in-house.Xometry has partnered with 3D Design On Demand solutions provider, ZVerse, tocreate 3D files for customers who need designs from scratch or a design modified.

Watch our video on PolyJet 3D Printing:

Xometry offers PolyJet rigid photopolymer (PJ3D), which is a 3D printing technology that builds parts out of a UV-curable resinwith high detail and the ability to apply different material properties. PJ3D works similar to an inkjet printer, where thousands of micro-dots of material are deposited and cured, layer by layer, to build a part from the bottom to the top. This process is best for test-fitting parts before moving to tooling, or getting thefeel of a rubbery or overmolded piece. One of the most underrated aspects of PolyJet is the ability to build multi-material parts which can have both rigid and rubber-like features on one print!

Here are the basic tolerances:

+/- 0.004", or +/- 0.001" per inch, whichever is greater. Build area up to 19 x 15 x 7"

PJ3D isa very fine detailed and accurate process. Although the material is not as robustas the FDM or SLS thermoplastics, the rigid and rubber-like photopolymers have the highest detail resolution for features like text, surface, and lip seals. PJ3D prints in 0.0012" layers (30 um). This process works best for final fit-checks before molding, highly detailed pieces, and parts that are used as sales models.

If you plan on painting your PolyJet part, it is recommend to go over it thoroughly with a wet abrasive pad to remove remnants of its gel-like support material. If your part requires more mechanical strength or high durability, you may want to consider other processes like SLS or FDM.

Check out our 3D Printed Surface Finishes Article to see how it looks!

Please use the following guidelines for tolerances and accuracy of 3D printed (additive manufactured) components. Note that this is based on typical results.

SLS: +/- 0.005" or +/- 0.002" per inch, whichever is greater, is typical. Build area up to13 x 13 x 20" (13" max dimension preferred)

HP MJF: +/- 0.012" or +/0.003" per inch, whichever is greater, is typical. Build area up to 15 x 11 x 15" (14 x 11 x 13" is the recommended usable area)

FDM: +/- 0.004" or +/- 0.002" per inch, whichever is greater, is typical. Build area upto 24 x 36 x 36"

SLA:+/- 0.004" or +/- 0.001" per inch, whichever is greater, is typical. Build area upto 29 x 25 x 21" (up to 58" is available through custom requests)

Carbon DLS:+/- 0.005” for the first inch is typical, plus +/- 0.002” for every inch thereafter. However, Xometry does not guarantee tolerances on the first attempt of a new design. Tolerance expectations can vary across different materials (e.g. elastomeric versus rigid materials).

PolyJet: +/- 0.004", or +/- 0.001" per inch, whichever is greater, is typical. Build area up to 19 x 15 x 7"

Additional notes:

All processes:Stresses during build, support strategy, and other geometry considerations may cause deviation in tolerances and flatness.Parts with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses may be prone to significant deviations or warp.Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis.

SLS (Selective Laser Sintering): Note that thicker geometries, large broad parts, and parts with uneven wall thicknesses may deviate due to thermal shrinkage and stress. This can look like warping or twisting. Even wall thicknessesand similar design guidelines as injection molded parts are encouraged. Very smallgaps and holes may be tighter than designed, a 0.006" offset of small gaps and holes will help these featuresachieve closer to CAD results. SLS prints in 0.0047" (120 um) layers.

HP MJF (HP Multi Jet Fusion): Note that thicker geometries, large broad parts, and parts with uneven wall thicknesses may deviate due to thermal shrinkage and stress. This can look like warping or twisting. Even wall thicknessesand similar design guidelines as injection molded parts are encouraged. Very smallgaps and holes may be tighter than designed, a 0.006" offset of small gaps and holes will help these featuresachieve closer to CAD results. HP MJF prints in 0.0031" (80 um) layers.

FDM (Fused Deposition Modeling):FDM works well for mechanical geometries, larger parts, and parts which may not require ultra-fine features. Very narrow pegs and lips may not resolve due to the bead thickness deposited. We recommend minimum feature size, including text features, to be at least 0.035"(0.045"is safest). FDM prints in 0.010" layers (254 um), 0.013" layers (330 um) on parts over 16" max dimension.

SLA (Stereolithography): SLA is a very fine detail and accurate process with a high variety of photopolymers that can mimic different properties. SLA materials can range from flexible (polypropylene-like), general purpose (ABS like), rigid (polycarbonate-like), and even highly stiff composite depending on the chosen material. SLA is a reliable option for testing fit prior to injection molding, getting a part with a smooth surface finish, or highly detailed features. SLA prints in 0.004" layers (100 um) with standard resolution and many materials have a high-resolution option at 0.002" (50 um) layers.

Carbon DLS (Digital Light Synthesis): Carbon DLS is a very fine detail and accurate process with thermally cured engineering materials. The cured materials are often urethane-based, such as flexible, rigid, and elastomer materials (FPU, RPU, EPU). There are also materials that behave like silicone, such as the urethane-based SIL material. Cyanate ester (CE) is a stiff and highly thermal resistant material.Urethane Methacrylate (UMA) is a general-purpose single-stage resin. Although curing is continuous, expect0.004" layers (100 um). This process works best for end-use applications that require a good blend of mechanical use and surface quality.

PolyJet (Polymer Jetting): PolyJet isa very fine detailed and accurate process. Although the material is not as robustas the FDM or SLS thermoplastics, the rigid and rubber-like photopolymers have the highest detail resolution for features like text, surface, and lip seals. PolyJet prints in 0.0012" layers (30 um). This process works best for final fit-checks before molding, over-mold prototypes, and parts that are used as sales models.

Inspections

We offer (6) different inspection options on the Inspection & Notes/Drawings tab in the quoting platform. All machined and sheet metal parts will receive a standard inspection included in the part price and lead time. All inspection options are described below including example dimensional inspection reports.

Standard: QC will verify that the part material, features, and finish are in accordance with the part requirements specified in the quote, CAD file, and/or print. If no dimensional print is provided with a part, QC measures to Xometry's Manufacturing Standards on dimensions they deem critical, such as overall size, holes, and depths. If a dimensional print is provided, QC will verify up to 20 dimensions they deem critical. Documentation will not be shipped with your parts.

Standard With Dimensional Report: QC will perform an inspection using calibrated tools where 100\% of all dimensions, attributes, dimensional locations, and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II with Zero rejects. A dimensional inspection report with a correlated ballooned print will be shipped with your part(s). A customer-supplied dimensional print is required for this inspection. Figure 1 shows an example of a Xometry dimensional inspection report with a correlated ballooned print. The numberof inspection points is subject to the applicable 100 maximum. Greater quantities require a manual quote and additional charges.

CMM Inspection With Dimensional Report: QC will perform an inspection using a Coordinate Measurement Machine (CMM) where 100\% of all dimensions, attributes, dimensional locations and print notes will be documented per our Statistical Sampling Plan based on ASQC Z1.4 2008 Level II with Zero rejects. A dimensional report with a correlated ballooned print will be shipped with your part(s). A customer-supplied dimensional print is required for this inspection.Figure 1 shows an example of a Xometry dimensional inspection report with a correlated ballooned print. The numberof inspection points is subject to the applicable 100 maximum. Greater quantities require a manual quote and additional charges.

First Article Inspection Report (per AS9102): QC will perform a First Article Inspection per the requirements specified in SAE Aerospace Standard (AS 9102) documentation. The purpose of the First Article Inspection is to provide objective evidence that all engineering design and specification requirements are properly understood, accounted for, verified, and documented. QC will maintain a quality record for customer review of accountability and planning, for performing periodic surveillance and audits to verify conformance, for evaluating root cause and corrective action for any non-conformances, and for problem investigations. A dimensional report with a correlated ballooned print will be shipped with your part(s). Random sampling is based on ANSI/ASQ Z1.4 Level II to an Acceptance Quality Level (AQL) of 1.0\%. A customer-specified dimensional print is required for a First Article Inspection. We will build the full lot and do the FAI form at final QC treating this lot as the first Article. If you want a 1 part and stop for approval please select custom inspection. The numberof inspection points is subject to the applicable 100 maximum. Greater quantities require a manual quote and additional charges.

Source Inspection: A Source Inspection audit is an inspection of purchasedproducts and process records at the supplier's premises to verify compliance with requirements before shipment to the customer. A Source Inspection can include but is not limited to requirements review, specification compliance, and a quality review of the manufacturer. A source inspection will be scheduled based on the order lead time and when parts are ready to ship. The order will ship after the source inspection is complete.

Custom: Choose this option if your part requires custom inspection requirements such as, but not limited to, the following: Non-Destructive Testing, Serialization, Custom Sampling Plan, or if you would like to provide your own inspection datasheet.

Non-Conformances & Rejected Parts

Rejected or non-conforming parts are documented and communicated based upon the inspection type selected. For Standard Inspections and Standard Plus Dimensional Inspections, Xometry may ship parts found with minor non-conformances (that cannot be reworked into compliance and are assumed to not impact the fit, form, or function of the part) for customer review. For other inspection types and any order where a Certificate of Conformance is selected, Xometry will acquire customer disposition on non-conformances for all issues that cannot be reworked into compliance prior to shipping. Post delivery non-conformance communication or RMA requests should be documented with the Order ID, part ID, quantity, and detailed description and sent to [email protected].

Figure 1. Xometry Sample Dimensional Inspection Report

3D printed parts do not receive full measurement inspection due to natural deviations that occur within the process. Please consult Xometry's Design Guides for a better understanding of each process and expected outcomes. Some materials, such as SLS, may have accessible holes drilled open to the CAD model before shipping.

With Xometry, you can order from quantity one to quantity many in a variety of manufacturing processes. Whether you're making one-off prototypes or are scaling low volume production runs, Xometry has a manufacturing solution for your project.

Volume discounts are available for a majority of Xometry's processes. Depending on the technology chosen, the discount may be just for one part in multiple quantities, or for multiple parts of the same material.

By changing the quantity on Xometry's instant quote, you can instantly see the updated pricing for the specified part(s). Also, by clicking the "more quantities" under the part price, you can preview different values at different quantities right away!

Pro Tip: Often machining, sheet metal, and casting processes have a higher upfront cost due to labor and setup. Adding more than one quantityto your order can be relatively inexpensive without major impacts on lead time and is a great way to make sure you have extrason hand!

Our job recommendation system uses a machine learning algorithm to compare each new job on your job board to past work that you've completed. Over time, the algorithm learns what types of jobs you tend to accept. The more work you complete, the more it learns about you. In making job recommendations, the system considers materials, quantity, and part complexity along with hundreds of geometric features that we extract from the CAD files. Jobs that are most similar to your past work will receive the highest scores. Whether you prefer large runs of quick-turn, simple parts or small quantities of complex parts, the system will learn your preferences and tend to rate those jobs higher. These recommendations only highlight jobs on your board that may be of interest. They won't limit what you see. You will still see all jobs based on the machine capabilities and other settings in your partner profile, whether or not they are similar to your past work.

At Xometry one of the most common problems we face with additive manufacturing is the risks related to thin walls and fragile features. We conducted a wall thickness stress test in our various printing processes to best understand the limitations of each process and made note of the results. We hope that our findings will prove to be insightful and help you refine your part designs for additive manufacturing! In addition to the results seen here, be sure to check out our design guides for further notes, design tips and recommendations for each process!

The Test Parameters

Our stress test starts by printing the same part in each of our main printing processes and materials. For this test, the following processes and materials were chosen: SLS Nylon, PJ3D Rigid Photopolymer, FDM ABS (0.010" Layer Height) & FDM ABS (0.013" Layer Height). We printed ABS in two layer heights as layer height can vary in the FDM process; larger parts are typically printed with a 0.013" layer height.

We designed the stress test part to push the limits of the machines and printing processes. The part contains a mix of knife edge features, walls and text at varying sizes and thicknesses. There are other features on the part which are designed to result in thin walls or fragile features that will consequently have high risk for failure.

SLS Durable WhiteNylon

Observations:

KnifeEdge Features: Overall we can see the knife edge points partially resolved. There is some noticeable warping on the thinnest knife edge (Marker 1 in the photo) which is expected with such a thin and comparatively tall feature. The tips of the knife edges appear to be cut-off due to the limitations of the process (Marker 2).

Thin-Wall Features: Generally SLS was able to resolve most of the thin walled features which come down to 0.25mm in thickness (thru-hole near edge, bottom of spherical pocket, rectangular wall array). Although these features resolved, we would not recommend features this thin as they will be inherently fragile.

Text Features: Overall the text resolved nicely, however you will notice as the text gets smaller, the sharpness seems to diminish as well. This is attributed to over-sintering combined with the tiny feature size (Marker 3).

PolyJet 3D Rigid Photopolymer (Semi-Gloss Black) Results

Observations:

KnifeEdge Features: Overall the knife edge features did not survive the print and post processing requirements for PJ3D. The thinner the base of the knife edge, the shorter the features ultimately ended up being (Marker 1).

Thin-Wall Features: The thin wall features also did not have much luck surviving the PJ3D process. Walls below 1mm thick were blasted away during support removal (Marker 2). Interestingly, the 1.5mm thick wall only partially survived, however the 1mm thick wall stood in place. The thin wall of the thru-hole was blown out during post processing, as seen on Marker 3.

Text Features: The text came out surprisingly well with little to no damage during post processing. While the results came out well in this test, generally small text runs the risk of being blown away or damaged due to the pressurized water jet used in support removal. The thicker the text is, the less likely it is to become damaged or blown away during post.

FDM ABS-M30 Dark Gray (0.010" Layer Height) Results

Observations:

KnifeEdge Features: The knife edge features partially resolved in this test. Similar to PJ3D, the thinner the base of the knife edge, the shorter the features ultimately ended up being (Marker 3).

Thin-Wall Features: Most of the thin walls came out, however the 0.25mm thick wall was much too thin and it simply was not printed at all. This demonstrates how smaller features can become "sweated out" in the FDM process (Markers 1 & 2). Due to the thin wall of the thru-hole, only 1 contour could be generated to make the feature. This 1 bead thick wall will be inherently fragile (Marker 4).

Text Features: The text struggled to resolve in this test. As the text becomes smaller and thinner, less tool paths can be generated and thus, certain text features only partially resolve or do not print at all (Marker 2).

FDM ABS-M30 White (0.013" Layer Height) Results

Observations:

KnifeEdge Features: Similar to the 0.010" layer height test, the knife edges partially resolved. As the base of the edges gets smaller, the resulting height is lower. The height of each knife edge ended up being cut shorter compared to the 0.010" layer height due to the larger layer height and bead size (Marker 3).

Thin-Wall Features: Only half of the thin walls printed; the 0.25mm & 0.5mm thick wall were too thin and they were not printed at all (Marker 1). The thin wall at the thru-hole ended up with odd bulging which caused the feature to be non-concentric. Any thinner and the machine would have likely not made a tool path here at all (Marker 4).

Text Features: Even less text resolved due to the larger bead size at the 0.013" layer height. As the text becomes smaller and thinner, less tool paths can be generated and thus, certain text features only partially resolve or do not print at all (Marker 2).

Xometry does not have a minimum order requirement. Feel free to order just one if that is all you need. Our services can help you scale from one-offs and prototypes all the way to mid- and high-volume production. Price per unit may decrease significantly over multiple quantities as well as some processes becoming cost-viable, such as injection molding or Carbon DLS 3D printing.

To request specific certifications for your RFQ(ex. NADCAP, ITAR, etc), please select the appropriate box on the RFQ form. If the certification you are looking for is not an option, please put that in the notes section. The selected certifications and notes are visible to the finishing partners. If there is anything else apart from certifications that you think the finisher bidding on your RFQ needs to know, include it in the notes section.

Customers have the ability to set the bidding period for partners. Customers will always be able to see their quotes on the RFQ Response Page. This does not mean that the quotes remain valid forever. Partners will specify how long their quote is valid for. This means quotes may expire at different times.

All RMAs or part quality issues are handled between the customer and their selected finishing partner.

The bidding period for each RFQ is set by the customer and may vary from 1 day to 2 weeks. You will see when all bids must be received in the RFQ details.

The maximum build volume of a part depends on the 3D printing technology used.

SLS Unfilled: Nylon 12 build area up to13" x 13" x 20" (13" max dimension preferred)

SLS Glass Filled: Glass Filled Nylon 12 build area up to26" x 15" x 23".

HP MJF: Build area up to 15" x 11" x 15"(14" x 11" x 13" is the recommended usable area)

FDM: Build area upto 36" x 24" x 36"

SLA:Build area upto 29" x 25" x 21"

Carbon DLS: Build area up to 7.4" x 4.6" x 12.8" (Parts with dimensions exceeding 4" x 4" x 6" will require manual review)

Xometry's online quote platform has a "Features" tab between the "Material" and "Finish" tabs. You can specify features such asthreads and tapped holes, inserts, specialty tolerances, surface roughness, and welding joints.

In the Notes/Drawing tab, please include a PDF drawing, reference image, or a note to indicate specific tolerances.

Although they are not optically clear, we have several materials that can hit different needs from light-pipes to case bodies. Stereolithography (SLA) is a go-to for transparent or translucentparts. Clear SLA options include Accura 60, Accura ClearVue, Somos WaterClear Ultra 10122, and Somos Watershed XC 11122. SLA parts will have an icicle-like translucency on unsupported features but are matte on features that require sacrificial support structure. Note that the default finish is matte, so standard or strip-and-ship finishes should be selected if natural translucency is required. SLA parts can be post finished or polished for higher levels of transparency.

Our PolyJet 3D printed Translucent Rigid Photopolymer (VeroClear) has a frosted translucentfinish which can be polished. We also offer FDM 3D printed ABSi, which has a diffused translucency in tints of natural, orange, and red (such ascar tail lights). FDM PC-ISO is also a translucent filament in it's natural state.

Ultimately no 3D process can make a perfect transparent or translucent solution out of the machine without significant processing. Milled materials like clear polycarbonate can sometimes be a better fit, but will have milling marks on any subtracted surface (they look like small swirls). Xometry can review to make a clear model through a significant amount of manual labor but often the price can be an order-of-magnitude higher than the material quote.
