Abstract: A 3D printer comprises a print head (500) for supplying pre-impregnated fiber composite filament (800) including inelastic axial fiber strands within thermoplastic matrix material. A first heating zone (1) between the filament supply and a heated nozzle (2) is heatable above the melting temperature of the matrix. A consolidation element (9) after the nozzle applies a consolidation force to the filament to attach the filament to the part. The nozzle is heatable to at least the melting temperature of the matrix. The filament is driven through the first heating zone into the nozzle. A cold zone (6) before the first heating zone maintains the temperature of the filament below the melting temperature of the matrix. A heat break (7) between the first heating zone and the nozzle creates a temperature gap between the first heating zone and the nozzle. The print head/consolidation element is movable in three degrees of freedom. The application further relates to a method for additive manufacturing of a part.
