3D printing is a rapid prototyping technology. It is a technology based on digital model file, using adhesive materials such as powder metal or plastic, and constructing objects by printing layer by layer. 3D printing is usually realized by a material printer using digital technology. It is often used in mold manufacturing, industrial design and other fields to make hand-made proofing. Therefore, the popularity of 3D printing technology has had a certain impact on the traditional hand board processing industry. The 3D printer does not need complicated maintenance, and the material line of the workbench can be cleaned quickly and simply after printing. Ordinary CNC machining needs special personnel to clean the machine tool and clean up the waste, and it takes a long time (labor cost). Because the early production of scaffold board is limited by conditions, most of the work is done by hand. Because of the long construction period, it is difficult to strictly meet the size requirements of appearance and structural drawings. With the popularization and application of 3D printing technology, choosing a good 3D printing manufacturer can avoid all kinds of problems encountered before, whether it is delivery or quality. Shenzhen Tianshunda 3D Printing is such a 3D printing technology company.
