Metal additive manufacturing using powder sheets (MAPS) of HEA CoNiCrFeMn: The effect of the polymer content on microstructure and mechanical properties

Metal additive using Powder Sheets is an innovative technology driven on eliminating loose powder in laser based additive manufacturing. The utilisation of a novel composite polymer-powder material enables the complete encapsulation of powder to mitigate safety risks and production issues associated with loose powder. This research demonstrates the versatility of this technology through varying the composition of the novel composite material, to deliver stronger, harder and more ductile materials. It is demonstrated that high-entropy-alloys can be printed with better mechanical properties while not altering the solid solution. Future applications arise in the field of multi-materials and coatings.
