China OEM Cnc Plastic Prototype Factories - Metal 3D printing – Mestech

Metal 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model file, which uses powder metal or plastic and other adhesive materials to construct objects by layer printing. The difference between metal 3D printing and plastic 3D printing: These are two technologies. The raw material of metal 3D printing is metal powder, which is produced and printed by laser high temperature sintering. The material used for plastic 3D printing is liquid, which is radiated to the liquid material by ultraviolet rays of different wavelengths, resulting in polymerization reaction and curing.
