| Abstract Scope |
One of the most limiting factors of Additive Manufacturing, specifically Laser Powder Bed Fusion, is low availability of different materials. This is most visible when it comes to light alloy powders, standard compositions of which are often not printable due to several factors. In this work we present a new aluminium based composite powder. The powder was modified with the use of powder metallurgy methods to simultaneously achieve printability, superior powder flow properties and high strength of the end product. Samples produced by means of Selective Laser Melting have not undergone hot cracking and exhibit exceptionally low porosity. Results of chemical, phase and morphology investigations of powders and printed samples are presented. |
