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.
Claims13
A method of manufacturing an object, comprising steps of:
- 3D printing the object comprising a metal, wherein the metal forms an outer shell substantially enclosing an interior volume and an infill portion within the interior volume of the object, the infill portion having structures defining a pattern and space within the interior volume;
- infiltrating the object with a metal powder such that the metal powder substantially surrounds and fills the structures defining the pattern and the space within the interior volume of the object;
- separately printing a shell wall of the metal;
- after infiltrating the object with the metal powder, enclosing the object with the shell wall;
- and
- sintering the object and the shell wall such that the resultant object forms a near solid part.
