The present invention relates to a thermoplastic composition comprising an amorphous polyamide polymer for use in 3D printing, the respective use and methods for forming objects by 3D printing using the thermoplastic compositions described herein.

Thermoplastic composition for 3D printing

The invention discloses a hot melt composition comprising a block copolymer consisting of at least two blocks as reaction product of a polyamide having a molecular weight of 5000 g/mol to 100000 g/mol and a modified olefin copolymer having a molecular weight of 3000 to 100000 g/mol and containing covalently bound organic acid anhydride groups to the polymer chain, wherein the polyamide has an amine number from 0.2 to 10 and the olefin copolymer has an acid number from 1 to 100.
