Abstract
Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.
Claims19
A composition for a three-dimensional printed part comprising:
- metal particles;
- and
- a fluid comprising metal nanoparticles, wherein the metal nanoparticles are uncoated or coated with a coating to prevent or reduce surface oxidation, and wherein the uncoated or coated metal nanoparticles are present in the fluid in a solution or dispersion.
A method of forming metal connections in a three-dimensional part, the method comprising:
- forming a layer of metal particles;
- selectively applying a fluid comprising metal nanoparticles, wherein the metal nanoparticles are uncoated or coated with a coating to prevent or reduce surface oxidation, and wherein the uncoated or coated metal nanoparticles are present in the fluid in a solution or dispersion;
- and
- heating or destabilizing to form the metal connections between the metal particles.
A composition for a three-dimensional printed part comprising:
- stainless steel powder particles;
- and
- a fluid comprising metal nanoparticles in an amount of up to 15 wt % based on the weight of a final part, and
- wherein the fluid comprises an ink vehicle comprising water, co-solvent(s), and/or surfactants(s).
