1. A thermoplastic 3D printing composition consisting of:
(a) at least 25 wt. % of an amorphous polyamide polymer, the polyamide polymer being a reaction product of:
a1) at least one dimerized fatty acid;
a2) optionally at least one mono carboxylic acid;
a3) optionally at least one linear dicarboxylic acid; and
a4) at least one linear diamine;
(b) at least 5 wt. % of a crystalline or semicrystalline thermoplastic polymer selected from the group consisting of polypropylene (PP), ethylvinylacetate (EVA), polyacrylate, polyamide different from (a) and combinations thereof;
(c) optionally at least 0.1 wt. % of a compatibilizing agent; and
(d) optionally at least 1 wt. % of a filler.
