Abstract
Recently, there has been increasing concern about the
sustainability of the manufacturing industry, one of the
major consumers of energy and raw materials, and
therefore, a major producer of greenhouse gas emissions
and waste. Additive manufacturing (AM) inherently
generates less waste than the conventional manufacturing.
In this study, the goal was to apply the concept of
circular economy into AM, by recovering process
sidestreams back to the feedstock material for Selective
Laser Melting. The objective was to prepare powder from
100 % scrap feedstock following two routes: 1) mechanical
milling of agglomerated residue powder, and 2) gas
atomization of solid scrap without extra alloying to
compensate possible alloy losses. The powder properties
were analysed and test specimens for the determination of
mechanical properties were made from the prepared powders
and commercial reference powder. Conducted test series
show that with recycled powders properties fully
comparable to reference can be achieved.
