Abstract
A process and printer systems for printing a three-dimensional object are disclosed. The processes may include providing a non-crosslinked peroxydicarbonate-branched polypropylene filament, flake, pellet, or powder adapted for one of a fused deposition modeling (ARBURG Plastic Freeforming) printer or a fused filament fabrication printer; and printing the non-crosslinked peroxydicarbonate-branched polypropylene with fused deposition modeling (ARBURG Plastic Freeforming) printer or a fused filament fabrication printer to form a three-dimensional article. The printer systems may include one or more print heads for printing a polymer provided in filament, powder, flake, or pellet form to form a three-dimensional article; and one or more feed systems for providing a non-crosslinked peroxydicarbonate-branched polypropylene to a respective print head.
