Abstract
A method and apparatus for forming a 3D article. According to the method, a composite filament material is formed from a UV curable material, a thermoset polymer material and at least one of filaments or fibers. After the composite is formed, the filament is dispensed to form the 3D article. Dispense is typically through a nozzle or other orifice that delivers the composite filament material as a bead of material. As the composite is dispensed, at least a portion of the composite material is exposed to UV radiation thereby curing a portion of the dispensed composite filament. The UV radiation is provided by a light source than can target discrete portions of the dispensed composite filament. For this purpose, the UV radiation source can be a light source integrated with the nozzle or a steered light source. As the composite filament is dispensed, UV radiation is directed onto the composite filament. If a steered light source is used, the composite filament is dispensed and light from the steered UV radiation source is directed to targeted regions of the composite filament, introducing cured zones or regions into the composite filament.
