Abstract

A method of fabricating (printing) parts utilizing flexible filaments includes anchoring a portion of a flexible filament to a substrate. A length of flexible filament is extended over the substrate while the flexible filament is in tension to thereby avoid buckling of the flexible filament. The flexible filament may comprise a thermoplastic material and fibers or other reinforcing materials whereby composite 3D parts can be fabricated.

Hybrid additive manufacturing methods using hybrid additively manufactured features for hybrid components

Patent Lacy, Benjamin Paul; Kottilingam, Srikanth Chandrudu; Schick, David Edward

A hybrid additive manufacturing method comprises building an additive structure on a pre-sintered preform base, wherein building the additive structure comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial shape. The hybrid additive manufacturing method further comprises modifying the initial shape of the pre-sintered preform base comprising the additive structure into a modified shape comprising the additive structure, and, joining the pre-sintered preform base in its modified shape to a component.
