Abstract

See full text

The invention relates to a method for forming a three-dimensional object by fused filament fabrication comprising the step of selectively dispensing a polymer composition containing a semi-crystalline copolyamide in accordance with the shape of a portion of a three-dimensional object, characterized that the semi-crystalline copolyamide comprises: a) At least 70 wt. % of aliphatic monomeric units derived from i. Aminoacid A, or ii. diamine B and diacid C, and b) At least 0.5 wt. % of further monomeric units derived from a cyclic monomer, wherein wt. % is with respect to the total weight of the semi-crystalline copolyamide. The invention relates also relates to objects attainable by this method and to the use of the said semi-crystalline copolyamide in fused filament fabrication.
