Success with selective laser sintering (SLS) begins with parts optimized for the SLS 3D printing process. This guide covers the important dimensions and design considerations to keep in mind when designing parts for the Fuse 1.

Note: These guidelines were developed with Formlabs Nylon 12 Powder printed at 110 microns on the Fuse 1. Since SLS printing behavior is geometry-dependent, these recommendations may not reflect all circumstances.
