Abstract
The In Process Control for L-PBF (IPCL) program leverages and in process inspection method recently developed and successfully demonstrated for NASA. This Layer Topographic Map or LTM method measures the surface if every melt layer using a commercial laser profilometer. LTM software detects, locates and identifies flawed regions within a layer for every layer in the part. It does so for several common flaw types common with powder bed processes. We will use LTM to find unfused or poorly fused powder and develop specific methods to repair these flaws by reapplying laser energy to re-melt the materiali.e. perform in process control (IPC). In a second series of trials we will demonstrate IPC where we couple LTM in process inspection to find and measure layer flaws, determine the proper repair procedure, and perform the repair/rework. Quality of the repaired flaws are determined from CT scans. Flightware has teamed once again with EWI, a large nonprofit R&D organization with equipment, staff and expertise in metal AdditiveManufacturing. Our team provides added value to DLA by combining in process inspection with in process control in Phase I, accelerating potential commercialization and insertion in the DLA supply chain.
