A Comparison of Polyamide 11 Mechanical Properties Between Laser Sintering and Traditional Molding

Tensile properties of laser sintering grade Polyamide-11 are processed using laser sintering, compression molding, and injection molding and the resultant mechanical properties are reported. The primary contributor to the enhanced mechanical properties of injection molded specimens is a fully healed polymer melt with preferred polymer chain orientation. It can be shown that laser sintering and compression molding specimens have comparable to compression molding specimens Ultimate Tensile Strength (UTS) and Elongation at Break (EOB).
