From Xometry's Manufacturing Standards:
- +/- 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).
- 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 maybe 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.
