| Abstract Scope |
Liquid metal jetting is an emerging metal additive manufacturing (AM) process requiring only solid metal feedstock to produce fully-dense parts through jetting molten metal droplets onto a moving platform. While opening a large application space due to a wide array of acceptable feedstock types, challenges related to part quality, processability, and limited understanding of printed properties limit industrial use. More specifically, droplet impingement on the build substrate, coalescence between adjacent droplets and solidification, as well as the chosen processing parameters can generate variations in both surface and bulk part characteristics which are not well understood. We present results of printing studies where aluminum alloy Al4008 was jetted onto metallic substrates at various processing parameters such as ejection frequency, spacing between droplets, hatch spacing, and the build plate surface temperature. Our results help manufacturers and researchers working to develop non-powder-based metal additive manufacturing methods. Prepared by LLNL under Contract DE-AC52-07NA27344. LLNL-ABS-843103-DRAFT. |
