Design Guidelines for SLS 3D Printing

Designing for Selective Laser Sintering (SLS) requires careful attention to wall thickness, tolerances, shrinkage, and part orientation. Unlike SLA or FDM, SLS allows complex geometries without support structures, but following design guidelines is essential for accuracy and repeatability. In this guide, we cover key rules for successful SLS design, from minimum feature sizes to assembly fits, as well as how industries like aerospace, automotive, and medical rely on precision in SLS printing.
