Abstract
Methods and assemblies for additive manufacturing portions of components with enhanced strength are provided. The assemblies comprise a first deposition head and an apparatus for causing one or more reinforcement fibers to extend more than two layers within previously-deposited layers of build material. The first deposition head is configured to deposit a plurality of layers of a filament comprising a reinforcement fiber and thermoplastic material. The apparatus may comprise a needle point configured to be inserted into the plurality of layers to displace the reinforcement fiber so that it extends two or more of the plurality of layers. The apparatus may additionally or alternatively comprise a second deposition head having a needle tip configured to be inserted into the plurality of layers to inject a length of a second filament comprising thermoplastic material and a reinforcement fiber so that the reinforcement fiber of the second filament extends two or more layers of the plurality of layers of the first filament.
