    Abstract: An additive manufacturing filament is provided, as are 3D manufacturing methods using the filament, and articles and composite materials made therefrom. The filament comprises a polymer composition, and the polymer composition comprises, in turn, at least 50 wt. % of a polyamide. The polyamide comprises recurring units R(PA1) from 30 mol % to 75 mol % recurring units R(PA1) according to formula (V′); and •from 25 mol % to 70 mol % of at least one of recurring units R(PA2), R(PA3) a and R(PA4), according to formulae (VI), (VII) and (VIII), respectively: •wherein ∘R1 and R2 are independently selected C1 to C3 alkyls; ∘Ri, at each location, is selected from the group consisting of an alkyl, an aryl, an alkali or alkaline earth metal sulfonate, an alkyl sulfonate, and a quaternary ammonium; ∘i is an integer from 0 to 10; ∘R3 is a C7-C16 alkyl, preferably a C7-C12 alkyl; ∘R4 is a C6 to C20 alkyl or a C6 to C20 aryl, preferably a C6 to C16 alkyl or a C6 to C16 aryl, more preferably a C6 to C12 alkyl or a C6 to C12 aryl; and ∘mol % is relative to the total moles of recurring units in the polyamide. The filament has a cylindrical geometry and a diameter between 0.5 mm and 5 mm.
