Abstract
Molds are produced by additive manufacturing and define parts cavities with part infills that can be ribbed or cellular. The molds are processed to sequentially remove infills to open part cavities to which part materials are introduced. Embedded or captured parts can be molded, and thermal channels can be provided to thermally isolate different materials.
Claims32
A method, comprising:
- selecting at least a mold material and a sacrificial material;
- and
- with an additive process, defining, layer-by-layer:
- at least a portion of a mold with the mold material, wherein the mold includes at least one mold ports, and
- defining at least a portion of a part cavity with the sacrificial material.
2 more elements
A mold, comprising a plurality of layers, wherein one or more layers contains at least one mold material and at least one sacrificial material, the sacrificial material forming a part infill corresponding to a part cavity.
