When orientation matters
- FDM – strength between layers (Z) is lower; we orient load-bearing features along the layer direction.
- SLA – support marks remain on surfaces in contact with supports; specify the visible surfaces.
- MJF / SLS – parts are nested throughout the build volume automatically; if orientation matters, note it in the comments.
Overhangs
In FDM, overhangs up to ~45° are usually printed without supports. Steeper ones need supports, which are removed and leave marks.
In the configurator
For FDM and SLA parts you will find “Orientation” – rotate the model or choose “Auto” (minimum height). The final position is confirmed by an engineer.
