We work to the tolerances of common standards, such as ISO 2768 for general tolerances, ISO 286 for fits and DIN 16742 for plastic parts. If a dimension needs to be tighter, put it in your request; we tell you up front whether the chosen technology can achieve it.

Quality and guarantee
How we check what we deliver, and what we do if a part isn't right.
Our guarantee
Checked before shipping
Every part is measured and visually checked against your file and the agreed specifications.
Finishing in-house
Sanding, painting and finishing are done in-house, also for parts printed at a partner.
Not right? We make it again
If a part deviates from your file or the agreed specifications, we remake it or refund it. Whether a design suits its application falls outside this guarantee.
