| Abstract Scope |
Bound Powder Extrusion (BPE) is a layer-by-layer additive manufacturing method utilizing filament with metal powders in polymer binders. BPE is promising for multi-material structures due to its ease of handling and low operation costs. Despite this, BPE has not been explored for multi-material. In this study, the Markforged Metal X System was explored with eight different combinations of copper, Inconel 625, 17-4 PH stainless steel, and three tool steels: A2, D2 and H13. Each combination was inspected for cracks after sintering due to each material having different shrinkage rates. Dilatometry was completed to see how the shrinkage rates differ during different points of their respective sintering cycles. SEM and EBSD will be done to view any microcracks as well as if there are any brittle intermetallics.
