If only a CAD model is supplied, the following tolerances in the table below apply to surfaces:
If a blueprint is provided, all tolerances of the print supersede the CAD model tolerancing above. Any supporting dimensioning on blueprints such as GD&T callouts, tap sizes, inserts, specific surface roughness must be followed.
Flat Sheet Metal Parts
Sheet metal parts that utilize stock material gauge thicknesses and require no bending or milled features. All flat sheet metal parts can meet a +/-0.005” (+/- 0.127mm).
Simple Sheet Metal Bend / One Surface
When designing parts with some type of bend with a standard bend radius, sheet metal tolerances are required to open. For simple bent parts, Xometry can offer a +/- 0.010” (+/- 0.254mm) tolerance for dimensions across a single bend. The bend radius itself is constrained to a +/- 1.0°
Multiple Sheet Metal Surface Bends
For dimensions measured over multiple bends, Xometry can offer a +/- 0.030 (0.762mm).
