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.
Claims14
A multi fluid kit for three-dimensional printing comprising:
- a first fluid comprising metal nanoparticles;
- and
- a second fluid comprising a destabilizing agent.
A method of forming metal connections in an intermediate three-dimensional part, the method comprising:
- forming a layer of powder metal particles;
- selectively applying a fluid comprising metal nanoparticles and a destabilizing agent on the layer of the powder metal particles;
- and
- heating or destabilizing the metal nanoparticles in the fluid to form metal connections.
A fluid for three-dimensional printing comprising:
- metal nanoparticles and a destabilizing agent in ink vehicle comprising water, co-solvent(s), and/or surfactant(s).
