| Abstract Scope |
Multi-jet fusion (MJF) is a novel additive manufacturing (AM) process for the powder-bed fusion of thermoplastic polymers. In recent years, MJF has been established as a promising manufacturing technique for the rapid prototyping and production of fully functional, large-scale components. However, the effects of common build volume parameters (such as part orientation, location, and spacing) on mechanical properties are currently not well understood. This study aims to provide a comprehensive description of the trends in mechanical properties observed in polyamide (PA)-11 and polyamide-12 samples printed via MJF. Tensile, flexural, and impact specimens were printed using varying build volume packing parameters and tested according to the corresponding ASTM standards. Fracture surfaces were studied and characterized to further understand the method of failure propagation through MJF-printed parts. The results of the present work are useful in determining an optimal packing algorithm for the purposes of optimizing desired mechanical properties of printed parts. |
