Laser Inversion Enables Multi-Material 3D Printing

Additive manufacturing, or 3D printing, uses digital manufacturing processes to fabricate components that are light, strong, and require no special tooling to produce. One of the most widely used manufacturing processes, selective laser sintering (SLS), prints parts out of micron-scale material powders using a laser — the laser heats the particles to the point where they fuse together to form a solid mass.
