The mechanical properties of 3D printed Nylon 11 tensile bars made via Selective Laser Sintering (SLS) and post-processed with Boundary Layer Automated Smoothing Technology (BLAST) have been evaluated. BLAST, a physical-chemical based process, can smooth a variety of thermoplastic polymers; hence, achieving an injection molding finish that allows for control of surface roughness, textures and gloss.  Consequently, the effect on mechanical properties of additive manufactured parts is controlled. Thermoplastic 3D printed parts via powder bed fusion (PBF) have surface imperfections such as internal voids, residue powder, or partially fused powder among the most common. Post-processing through BLAST significantly enhances the mechanical performance of 3D printed parts. The results of this revolutionary technology show the improvement in elongation at break after post-processing Nylon 11 parts.

Learning Objectives:
