| description | A method for determining whether build powder is fit for reuse in a laser powder bed fusion additive manufacturing (LPBF) process includes constructing a model for determining a Powder Reuse Index indicative of whether build powder is fit for reuse in the LPBF process based upon LPBF process operating parameters. A build design is selected to be built using the LPBF process to collect data for constructing the model for determining the Powder Reuse Index. A plurality of test pieces the selected build design are built using a LPBF system with different layouts or set ups. Quality characteristics are determined for each of the plurality of test pieces and, using the quality characteristics for each of the plurality of test pieces, a relative importance of each LPBF process build parameter as to whether a batch of build powder is fit for reuse is determined. |
