Xometry's instant quoting page allows a user to customize the material, features, finish, and add notes to their custom manufacturing project. Xometry offers many standard finishing options which instantly price online:
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.
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.
In addition to the removal of support structures, the part surface is media blasted to provide a uniform finish.
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 parts are built with support material that is removed during post-processing. The part surfaces are left with fine layer lines.
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
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.
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.
Xometry provides additional HP Multi Jet Fusion finishing options, including but not limited to: sanding, painting, and plating to meet your needs.
Support material is removed and parts are cleaned.

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.
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
Natural finish - Built vertical - Edge is supported
(Support dots were left intact to easier identify supported surface.)
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.
Only supported surfaces are sanded. Parts will still have visible layering. Quick dry clear coat is applied to enhance natural clarity.
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.
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.
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.
Standard nylon 12 dyed in the specified color. Dye penetrates 0.25 mm of part's surface.
Parts are plated with ~0.1 mm / 0.004 in nickel. Plating increases part strength, stiffness, and environmental resistance.
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.

Will conform to MIL-A-8625, Type II, Class 1. MIL-A-8625, Type 1/1B (Chromic Acid Anodize), and ASTM D3933 (Phosphoric Acid Anodize) must be manually quoted as a "Custom" finish.
Anodize, Black and Color
A Type II anodize. Provides increased corrosion resistance and can be used as a base for paint and other finishes. Standard colors are black, blue, gold, green, orange, purple, red, and yellow. Anodized colors cannot be matched to specific Pantone or RAL colors. Thickness ranges from .0002”-.0012”. Will conform to MIL-A-8625 Type II, Class 2. MIL-A-8625, Type 1/1B (Chromic Acid Anodize) and ASTM D3933 (Phosphoric Acid Anodize) must be manually quoted as a "Custom" finish.
Type III. A thicker layer of standard anodizing, making it more durable. Can be used as a base for paint and other finishes. Standard colors are black, clear/unpigmented, and gray. Colors tend to come out slightly dark due to thickness. Anodized colors cannot be matched to specific Pantone or RAL colors. Thickness is generally 0.002". Will conform to MIL-A-8625, Type III, Class 1/2. Finishes like AMS 2482 & MIL-A-63576 (PTFE Impregnated Hardcoat) should be specified as a "Custom" finish, requiring a manual quote.
Anodize, PTFE Impregnated Hardcoat
A hard coat anodize process that embeds PTFE to create a self-lubricating, dry contact surface with Type 3 hard coat’s protective properties. This finish can be used on aluminum alloys or titanium and increases the service life of the product. This finish conforms to the AMS-2482 Type 1 Hard Coat Anodizing with Teflon (Non-Dyed) specification (also called MIL-A-63576 Type 1). This finish color is black.
Anodize, Titanium (Tiodize)
A surface finish for titanium per AMS-2488 Type 2 specification. Also called Tiodize, this finish increases fatigue strength and the wear resistance of a part. Titanium anodized parts are common in aerospace and medical device manufacturing. Non-pigmented titanium anodize finishes will dull shine.
