When you order parts made with Xometry's Sheet Cutting manufacturing service, we offer several part processing and finishing options to meet your needs. The sections and video below will cover some of these options in detail.
As Cut, No Deburring
At our discretion, the parts may be tabbed together on the source sheet, to each other, or to a support structure. You are then responsible for separating the parts from the sheet, as well as any surface cleanup or deburring.
As Cut is a good choice when you want to save money, when the parts will not be touched or seen, or when you wish to finish them yourself.
Note: In some cases, the parts may arrive detabbed if we feel it’s easier to make or ship them that way, but this is not guaranteed unless you order one of the detabbing options.
Example of as cut parts attached to stainless steel source sheet:
Note the burrs visible inside the “X,” typical of laser cutting.
Note the burrs along the cut line, as well as burrs caused by laser spatter (slag) in this part.
These may be present unless the deburring option is chosen.
Separated with Tabs Removed
Parts will be guaranteed to be separated from each other, and tabs will be ground off. However, the parts will not be deburred. This saves you time manually de-tabbing parts and removes the tab when it’s not needed for fitment or other purposes.
Note: Laser and waterjet cut parts may have fine burrs after cutting (see the section on As Cut). The area where tabs are ground or sanded off may have a slightly different texture or appearance than the rest of the part.
Separated with Tabs, Burrs, Scratches and Discoloration Removed
This option is recommended for parts that will be handled or used in mechanical applications where burrs could become problematic, such as with aerospace or medical-industry parts. Parts will be separated, the tab will be ground off, and all burrs will be removed, including laser spatter (slag).
Additionally, a simple surface cleanup will be performed on all parts to mitigate handling scratches, discoloration due to the laser process, etc. The parts will be cleaned with an appropriate solvent, such as water, isopropyl alcohol, or acetone, to remove any surface debris and surface markings from the material manufacturer.
The surface finishing method used will be at Xometry’s discretion and may include hand sanding, tumbling, bead blasting, or using a finishing machine. If there is a particular surface finish you need for your parts, choose one from the finish drop-down menu.
Note: When you choose a finish other than Standard (e.g., anodized or powder coated), Separated with Basic Surface Cleanup will be applied automatically.
Other Bare Metal Surface Finishes
For the best possible appearance on bare metal parts, you may wish to add an additional mechanical surface finish, such as Bead-Blasted or Tumbled. Keep in mind that for these or any finish chosen from the Finish list, the Separated with Basic Surface Cleanup de-tabbing process will be applied automatically.
Bead Blast
Parts are finished in a blasting cabinet with a high-pressure stream of fine glass beads, typically using 80-grit media applied between 70-100 psi. This gives the surface of the parts a uniform matte or satin-like cosmetic appearance.
We do not recommend glass bead blasting before applying chemically processed coatings such as anodizing and chem-film, as glass beads can become embedded into the surface, interfering with their application.
Tumbled
Parts are finished in a vibratory or rotary tumbler with tumbling media. This provides an even stippled finish over the entire part's face and tends to round sharp corners and edges.
Other Finishes
In addition to mechanical finishes, we offer other options for metals such as anodizing, chem-film, metal plating, electropolishing, powder coating, and more! Visit our Metal Finishes Gallery for examples to learn more about our other metal finishes.
