Zusammenfassung:	Disclosed are additive manufacturing compositions comprising: A) 100 to 30 weight percent of a polyamide composition comprising: a) 95 to 5 weight percent of at least one semi-crystalline copolyamide having a melting point, said semi-crystalline copolyamide comprising: i) 5 to 40 mole percent aromatic repeat units derived from one or more aromatic dicarboxylic acids with 8 to 20 carbon atoms and at least one aliphatic diamine with 4 to 20 carbon atoms; and ii) 60 to 95 mole percent aliphatic repeat units derived from one or more aliphatic dicarboxylic acids with 6 to 20 carbon atoms and one or more aliphatic diamines with 4 to 20 carbon atoms; b) 5 to 95 weight percent of at least one amorphous copolyamide comprising: iii) 60 to 90 mole percent aromatic repeat units derived from isophthalic acid and at least one aliphatic diamine with 4 to 20 carbon atoms; and iv) 10 to 40 mole percent aromatic repeat units derived from terephthalic acid and at least one aliphatic diamine with 4 to 20 carbon atoms; and B) 0 to 70 weight percent of at least one additive. These compositions provide 3D printed articles having improved physical properties.
