technical background

At present, 3D printing is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Most of the existing 3D printers use hot melt nozzles, laser beams, light curing and other methods to accumulate and bond metal powder, plastic and other materials layer by layer, and finally superimpose and shape them to produce physical products. Compared with traditional manufacturing methods such as turning, milling, planing, and grinding, it has the advantages of low labor intensity, high speed, and low price.
