Abstract
This document describes systems and method of embedded printing for additive manufacturing. A print material is printed into a support material. The print material and the support material each have a fluid phase and a solid phase. The print material transitions from the fluid phase to the solid phase based on a fluid-fluid interaction with the support material. One or more parameters of the support material can be adjusted to cause a diffusion rate of the print material into the support material during the fluid-fluid interaction to be less than a threshold value. Multiple print materials can be printed into the support material simultaneously.
Claims13
A method for additive manufacturing, comprising:
- moving an injector inside a support material comprising a first fluid phase, a first solid phase, and a buffering material having a predetermined concentration, the support material configured to flow in response to experiencing a mechanical stress from the injector
- injecting a print material from the injector into the support material;
- transitioning the print material from a second fluid phase to a second solid phase at a predetermined rate in the support material based on a fluid-fluid interaction between the buffering material and the first fluid phase of the support material and the second fluid phase of the print material;
- and
- separating the support material from the print material.
