Beschreibung
Zusammenfassung:	A method for additive manufacturing by Fused Deposition Modeling of a preform, is disclosed wherein the method comprises: a) supplying a continuous filament that comprises: (i) one inner core consisting of a bundle of fibers and (ii) an outer binder coating, which completely wraps said inner core; b) feeding the continuous filament to an extruder at a feed rate, the extruder heating the continuous filament to a temperature which is between the softening temperature of the binder and the melting temperature of the binder, and below the melting temperature of the fibers; and c) 3D deposition of the continuous filament on a base surface in at least one or more successive layers to obtain the preform. The obtained preform is also disclosed and a reinforced composite part obtained therefrom.
