There is no given set of tolerances that works for all processes and materials.In each case, the final tolerance on your part will depend on a number of factors, including but not limited to:
1. Part size/design geometry/number, type and size
2. Material/Surface Finish/Manufacturing Process
3. Once your order is confirmed, we will review your design and provide a design for manufacturing review, pointing out any areas where the required tolerances may not be achieved.It's helpful if you can specify which areas of the design have critical tolerances of necessity, and that can be modified slightly if necessary to reduce the time and cost involved.Here are some general tolerance guidelines:
4. General tolerances for CNC machining in metals and plastics
5. Plastic injection resistance
6. The general tolerance of metal 3D printing is +/- 0.5mm
7. Expect +/- 0.15% shrinkage for vacuum casting
8. All manufacturing and technical specifications need to be clearly specified in 2D drawings in order to proceed.
