| 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 as high as 400Hz. While opening a large application space due to a wide array of acceptable feedstock forms, questions about part quality and processability of different materials limit industrial use. Being a non-fusion based AM technique, processing parameters such as buildplate temperature can likely influence part densification, microstructure, and tensile properties, but these relationships 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 buildplate temperatures and layer-wise rastering angles to understand their influence on densification, microstructure, and tensile properties. 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-847002. |
