Planned: diagram showing anisotropy (layers vs loads) for a mechanical part.

Design and orientation

Avoid stress concentrations; plan tolerances and clearance for assembly. Layer orientation should follow primary loads as far as possible — it is often more decisive than filament choice alone.

Materials and resources

The in-depth guide which material for a mechanical 3D-printed part covers PETG, ABS, PA, and edge cases. Sheets for PETG, ABS, and PA / nylon add printing precautions.

Reliability in service

Document load, impact, temperature, and expected service life: without these, even a good material can yield an under-designed part. For a first budget estimate, use the 3D printing cost calculator before sending your specification.
