Brief Summary
3D print metal or ceramic powders using Fused Depositing Modeling
Problem Statement
Current 3D printing of metals is done by techniques that will melt the metal, or techniques that involve forming and shaping of parts with metal powders with the assistance of polymeric binder such as "binder-jetting" and FDM techniques.
Technology Description
This invention overcomes some of the difficulties of the existing techniques and combines their advantages. In this process, powders are first coated with a polymeric binder. The powder is then fed to a nozzle which is heated to soften the polymeric binder. The nozzle is manipulated by a 3D printing software and deposits the powder particles spot by spot and layer by layer. This is best for high melting point metal powder, inorganic ceramic powders, and other materials that are not suitable for melting for various reasons.
Benefit
- Dry build material powder.
- Metal, ceramic or other materials.
- More efficient, lower cost, and flexible for 3D printing of a wide range of materials.
