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： A process for producing articles with an extrusion-based additive manufacturing system using a consumable filament made from or containing a propylene polymer composition made from or containing:
A) from 20% to 60% by weight of a heterophasic propylene copolymer;
B) from 5% to 33% by weight of a propylene homopolymer or copolymer, wherein the copolymer contains up to 5% by weight of an alpha olefin;
C) from 2% to 15% by weight of an elastomeric block copolymer made from or containing styrene;
D) from 4% to 32% by weight of an elastomeric ethylene copolymer;
E) from 5% to 50% by weight of a glass material as filler; and
F) from 0.1% to 5% by weight of compatibilizer.-
