| Abstract Scope |
This work reports the results achieved in the framework of the PoSAddive project by using a new AM technology called MAPS (Metal Additive manufacturing using Powder Sheets).
MAPS employs flexible binder-powder sheets as feedstock material, reducing the health risks related to loose powders. During MAPS, a laser beam interacts with such sheets to create, layer-by-layer, a metallic structure.
The present contribution investigates the properties of MAPS samples, focusing on the effect of the polymeric binder. First, the feedstock was analyzed by SEM. Then, the printed material was characterized to assess the microstructure, mechanical properties, and the influence of the polymeric binder on the final properties. The experimental work was backed by thermodynamic simulation by CALPHAD method.
This research shows the first very promising results achieved by MAPS and allows drawing useful information for the appropriate design of powder sheets to achieve highly dense materials with a low number of inclusions. |
