Abstract Scope |
Molten metal jetting (MMJ) deposits droplets of liquid metal to additively manufacture parts droplet by droplet. As material is only deposited where required, MMJ may lend itself to repairing damaged parts. Here we use MMJ to fill in machined grooves on cast aluminum plate to understand how cast parts can be repaired. We find the groove shape has a significant role in “repairability” with round grooves being easier to fill in than other groove shapes. Finally, we compare the tensile strength of repaired and as cast tensile bars. Repaired tensile bars have reduced tensile strength likely caused by the inherent heating during the MMJ process. When post-print heat treatments are performed, tensile strength is regained in repaired parts. Prepared by LLNL under Contract DE-AC52-07NA27344. LLNL-ABS-1095114. |
