SLA: build orientation impact on the mechanical properties of 3d prints

0

Can anyone share practical insights on the impact of different build orientations on the mechanical properties of SLA printed parts, particularly for eventual load-bearing applications? 

I would appreciate any practical experience examples.

Thanks

Hi David, I never heard of a significant difference in properties and orientation in SLA. Where a bigger difference is, is the curing after the printing. It changes the properties and this information, you can find in the datasheets. More important to know in SLA is, that the properties are just temporary, cause resin parts are aging fast and are quite UV sensible. BR

      I’ve heard that the parts oriented horizontally generally show a 20-30% improvement in tensile strength compared to vertical orientations in SLA 3D printing. But I don’t have any practical experience.
