摘要： An extrusion-based additive manufacturing process including the step of selectively depositing a molten thermoplastic material (P) on a film or sheet made from or containing a polymer blend obtained by melt blending a mixture made from or containing:
(A) 60% to 98.8% by weight of a polyolefin;
(B) 0.1% to 30% by weight of a compatibilizer;
(C) 0.05% to 20% by weight of an amino resin; and
(D) 0% to 5% by weight of an additive,
wherein the amounts of (A), (B), (C) and (D) are based on the total weight of (A)+(B)+(C)+(D).-

摘要： An extrusion additive manufacturing process including the step of extruding a polyethylene composition having a melt flow index MIE of at least 0.1 g/10 min., the composition made from or containing: A) from 1% to 40% by weight of a polyethylene component having a weight average molar mass Mw, as measured by GPC (Gel Permeation Chromatography), equal to or higher than 1,000,000 g/mol; B) from 1% to 95% by weight of a polyethylene component having a Mw value from 50,000 to 500,000 g/mol; and C) from 1% to 59% by weight of a polyethylene component having a Mw value equal to or lower than 5,000 g/mol.
