摘要： An extrusion-based production system (300), comprising: a filament roll with a thermoplastic filament (2); at least one assembly with: an entrance (3) for receiving the filament; an exit (4) for delivering the filament, a channel (5) between the entrance and exit; a first and second rotatable component (10, 20), respectively rotatable about a first/second axis (12, 22), and having first/second external ridges (11, 21), wherein, when a filament is introduced into the channel, and the at least one assembly is rotated with respect to the filament (2), the rotatable components rotate about their respective axis, and the axes move about the filament such that the components mainly roll over the filament, and the external ridges (11) penetrate at least partially into the filament (2). A method for feeding a thermoplastic filament.
