Microstructure Evolution in Additively Manufactured Steel Molds: A Review

Over the last decade, developments in metal additive manufacturing (AM) have opened up new possibilities in various industries. Current metal AM technologies are now capable of processing a larger selection of metals, including steel mold materials such as H13 and P20. In the injection molding industry, mold makers have implemented metal AM technologies to 3D print steel molds. The main challenge currently faced by mold makers is to 3D print...
