3d printing News
Printing Shape-Changing 3D Structures With Light
CAMBRIDGE, Mass., Sept. 23, 2016 — A high-resolution 3D printing process that uses light from a projector to print patterns on shape-memory polymers (SMPs) was used to fabricate structures that can morph back to their original shape quickly. The process, called microstereolithography, could be useful for creating structures for a variety of applications, from biomedical devices to photovoltaic solar cells.
Landscape Shifting for Laser Materials Processing
Aug 1, 2016 — Not long ago, laser materials processing was characterized by four basic manufacturing operations: surface treatment, marking, removal and welding. Buoyed by advances in additive materials deposition, the proliferation of laser annealing for thin...
