[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, and uses bondable materials such as powdered metal or plastic to construct objects by printing layer by layer. 3D printing is usually achieved using a digital technology material printer. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and then gradually used for the direct manufacturing of some products.
