Abstract Scope |
Liquid metal jetting based-AM is an emerging process requiring only raw metal ingot to produce near-fully dense parts through jetting molten metal at frequencies in excess of 400Hz. While opening a large application space due to a wide array of acceptable feedstocks, questions about part quality and processability of different materials limit industrial use. 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 to date. To this end, we present results of printing studies where aluminum alloy Al4008 was jetted onto metallic substrates at various input processing parameters such as ejection frequency, spacing between droplets, hatch spacing, and the buildplate 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-833717. |
