A: SLS (Selective Laser Sintering) is a 3D printing technique that uses a laser to fuse together small particles of plastic, metal, glass, or ceramic powder into a solid object. SLA (stereolithography) uses an ultraviolet (UV) laser to cure (harden) photosensitive resin into the desired shape.
A: Designers use 3D printers to quickly create product models and prototypes, but they're increasingly being used to make final products, as well. Among the items made with 3D printers are shoe designs, furniture, wax castings for making jewelry, tools, tripods, gift and novelty items, and toys.
A: Three-dimensional (3D) printing is an additive manufacturing process that creates a physical object from a digital design. The process works by laying down thin layers of material in the form of liquid or powdered plastic, metal or cement, and then fusing the layers together.
