Abstract
A method of producing parts from two distinct classes of materials utilizes depositing a first class material and a second class material on a deposition surface where the first class material forms a three-dimensional shape defined by the interface of the first class material and the second class material. The first class material is unified and the second class material is removed therefrom to form a three-dimensional part of the first class material. Preferably, the first and second class materials are deposited in layers.
Claims20
A method of producing parts comprising:
- depositing a first class material and a second class material in multiple layers, wherein each layer of said multiple layers comprises the first class material and the second class material, and wherein the first class material forms a three dimensional shape defined by the interface of said first class material and said second class material;
- compacting the deposited first class and second class material by exerting an external force thereto;
- unifying the first class material after the steps of depositing and compacting all layers of said multiple layers;
- and
- removing the second class material from a three dimensional part formed of the first class material.
