ADDITIVE MANUFACTURING USING MISCIBLE MATERIALS

摘要

An object can be formed in an additive manufacturing process, such as FDM, by providing a substrate having at least a surface that is made of a first material, and forming one or more layers of a second material on the surface of the substrate, wherein a Hildebrand solubility parameter of the second material is within about 5% of a Hildebrand solubility parameter of the first material. In this manner, the object part formed by the one or more layers of the second material may be incorporated into the object. In an example, the object includes a first portion comprised of the one or more layers of the second material and a second portion comprised of the substrate, the first portion having a first haze value and the second portion having a second haze value, wherein a percent difference between the first haze value and the second haze value is equal to or greater than about 165%.

主权项

1. A method comprising:
removably mounting a preformed substrate to a platform, the preformed substrate having a surface including a first material; forming one or more layers of a second material on the surface of the preformed substrate by an additive manufacturing process, wherein a Hildebrand solubility parameter of the second material is within about 5% of a Hildebrand solubility parameter of the first material; and producing an object comprising the preformed substrate and the one or more layers of the second material bonded to the preformed substrate.
