Abstract: A flexible 3D printing feedstock material is disclosed. The flexible 3D printing feedstock material includes 45-80 vol % of a powder having at least one of a metal powder and a ceramic powder, 0-5 vol % of a compatibilizer, 10-35 vol % of a soluble flexibilizer, and 5-35 vol % of a non-soluble binder component. Methods of forming the flexible 3D printing feedstock material by melt mixing the components are disclosed. Methods of producing a 3D printed part by operating a fused deposition modeling 3D printer loaded with a filament formed of the 3D printing feedstock material are also disclosed.

Abstract: Metal composites, tooling and methods of additively manufacturing these are disclosed. Metal objects and structures as provided herein are additively manufactured from metal having an infill pattern infiltrated with a metal powder. Also provided herein are methods of forming such objects and structures. Methods include additively manufacturing a metal structure having an interior printed using an infill. Steps can further include infiltrating the printed infill of the structure with a powder metal thereby forming a composite.

Abstract: A 3D printing apparatus and method prints a partial part, and continues to print the part after the partially-printed part has been rotated. Each partial printing operation may include reinforcement via application of one or more layers of continuous fiber. The rotation and continued printing of the partially-printed part allows for fiber orientation in different orientations for the printed part.

Abstract: Metal composites, tooling and methods of additively manufacturing these are disclosed. Metal objects and structures as provided herein are additively manufactured from metal having an infill pattern infiltrated with a second metal. Also provided herein are methods of forming such objects and structures. Methods include additively manufacturing a metal structure having an interior printed using an infill. Steps can further include infiltrating the printed infill of the structure with a liquid metal thereby forming a bi-metal composite.
