Does part orientation affect mechanical properties in MJF printing?

Hi everyone, I’m designing functional end-use parts for MJF 3D printing. These parts need to withstand repeated mechanical stress, particularly bending and torsion. I’ve read conflicting information on how part orientation during printing can influence the mechanical properties of MJF-printed parts. Does anyone have experience or data showing how orientation affects strength, especially in load-bearing applications?

Solved by Paolo F.

In my experience with MJF, the mechanical properties are pretty isotropic, so orientation doesn't have a huge impact on strength or durability. I've found that the parts generally perform the same regardless of direction. However, orientation is still important for surface finish—tilting the part slightly during the build can help achieve a more consistent matte finish across all surfaces. If your focus is on aesthetics or minimizing post-processing, it's something worth considering, but for mechanical properties, you should be good in any orientation.
