Summary
During metal printing, the source powder around the fused material is exposed to high
temperatures, oxidation and other chemical processes that determine its properties. One of the
few explored issues concerning 3D-printed metals is the question, how many recycling steps
can the powder undergo without significant changes in a quality of the printed product. This
project aims at tracing the effect of subsequent reusing the original metallic powder on various
kinds of material “quality metrics”. The major concern is to find out how are the powder and the
printed material affected by recycling and to what extent. Both the material mechanical and
structural aspects will be emphasized. We will focus on the effect of recycling on high- and lowcycle
mechanical properties, which are mentioned in the literature inadequately to their
importance. Their evolution will be quantified by both conventional and progressive methods,
which may be highly effective in assessing the powder condition (thermal response, digital
image correlation, advanced approach to detecting the plastic anisotropy).
