Abstract Scope |
Liquid metal jetting droplet-on-demand (LMJ-DoD) additive manufacturing is an attractive alternative to the industry standard, laser-based techniques: low feedstock footprint, low overbuild quantity, less contamination and inclusions, and compatible with a larger range of materials. However, little has been reported on the crucial process-structure-properties-performance (PSPP) relationships for the LMJ-DoD process to consistently produce robust metal parts. We investigate the effects of various build plate temperatures and fill patterns on the microstructure, density, hardness, and tensile strength of tin parts created with our custom LMJ-DoD setup. The results and methods of this study will help guide future work in optimizing the liquid metal jetting process to reliably print parts using a wide variety of metal feedstocks.
