Environmental impact assessment of Arburg plastic freeforming additive manufacturing

Arburg Plastic Freeforming (APF) is an advanced and original Additive Manufacturing (AM) technology that melts granulate thermoplastics through a heated reciprocating screw and deposits droplets layer-by-layer to build three-dimensional objects. The process requires technological decisions, the environmental repercussions of which are still unexplored. This study provides a parametric cradle-to-gate life-cycle assessment of the APF process based...
