File guidelines

Draft template. A lawyer must review it before the site goes live.

Following these points gives you an exact price and a good print.

File format

We accept STL, 3MF and OBJ. Export in millimetres. If you work in inches, we offer a one-click conversion after upload.

Closed mesh

The model must be a closed solid without holes. We repair small defects automatically and tell you if a file cannot be repaired.

Size

Our print area is shown when a model is too large. Larger models must be split into parts in your CAD program.

Thin details

Walls should be at least 1.2 mm thick. Details under 0.8 mm may not print well.

Quality and infill

Draft is fastest and cheapest. Fine gives smoother surfaces but takes longer. Infill of 15% suits most parts. Use 50% or more for parts under load.
