[0002] 3D printing is a rapid prototyping process that uses layer-by-layer stacking to create three-dimensional models. Its operation process is similar to that of a traditional printer, but 3D printers stack liquid photosensitive resin materials, molten plastic filaments, gypsum powder and other materials layer by layer through spraying adhesives or extrusion to form a three-dimensional entity.
