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:
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 supporting 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.)
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 photo gallery.
CNC and Sheet Metal
Standard
Part is cleaned and deburred. No surface finishes are applied.
Anodize, Clear
A Type II anodize. Provides increased corrosion resistance and is used as a base for paint and other finishes. Can Darken the part slightly. Thickness ranges from .0002”- .0012”. Will conform to MIL-A-8625
Anodize, Black & Color
A Type II anodize. Provides increased corrosion resistance and can be used as a base for paint and other finishes. Please provide color preference in ‘Notes’ section. Thickness ranges from .0002”-.0012”. Will conform to MIL-A-8625
Anodize, Hardcoat
Type III. A thicker layer of standard anodizing, making it more durable. Can be used as a base for paint and other finishes. Include color choice in ‘Notes’ section. Colors tend to come out slightly dark due to thickness. Thickness is generally 0.002". Will conform to MIL-A-8625
Bead Blast
Part is cleaned, deburred, and placed in an abrasive blaster where surface deposits are removed by applying fine glass beads at high pressure, without damaging the surface. Finish is matte.
Chem Film (Chromate Conversion Coating)
Provides corrosion resistance and good conductivity properties. Can be used as a base for paint. Can leave surface yellow/gold. Adds very little thickness, about 0.00001”-0.00004”. Chem film will conform to MIL-DTL-5541.
Electroless Nickel Plating
Provides uniform nickel coating which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will be brighter. Thickness starts at .0001”. Conforms to MIL-C-26074.
Electropolishing
An electrochemical process cleans steel parts to reduce corrosion and improve appearance, by making the metal brighter. Removes about 0.0001”-0.0025” of the metal. Conforms to ASTM B912.
Heat Treatment
Heat treatment of metal parts to provide improved material properties. Includes Rockwell heat treatment, annealing, and other heat treatments. Specify treatment required in the 'Notes' section, or an attached drawing. Conforms to ASTM B917.
Passivation
Improves corrosion resistance for 200, 300, and 400 series and precipitation hardened corrosion-resistant steels. Thickness is negligable, about .0000001”. Conforms to ASTM A967.
Plating, Gold
Gold Plating provides good corrosion and tarnish resistance. Gold has low contact resistance, with excellent conductivity and solderability. Makes part appear like gold. Thickness is about .00002”-.0003”. Conforms to MIL-G-45204.
Plating, Silver
Electroplating of silver provides good corrosion resistance but easily tarnishes. Silver offers high solderability and electrical conductivity. Makes part appear like silver. Thickness is about .00002”-.0003”. Conforms to QQ-S-365.
Powder Coating
Provides a continuous, protective color finish on parts using an evenly applied, heat-cured paint. Include color choice in ‘Notes’ section. Has matte appearance. Thickness is usually .006”-.012”. Conforms to ASTM D7803.
