Description
technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printing device capable of reducing warping of three-dimensional printing products. Background technique [0002] Today, with the rapid development of industry and manufacturing industry, the traditional manufacturing processing technology can no longer meet many high-precision, high-complexity, and special-shaped processing requirements. The method came into being: 3D printing. With its many advantages, 3D printing technology has become one of the most popular and most vital technologies in the field of new manufacturing. Unlike ordinary printers that can only move in two-dimensional directions, 3D printing uses 3D CAD data models to control machines. The printing materials are stacked layer by layer, and the physical restoration of the 3D model is realized through stacking. This manufacturing method not only shortens the development cycle...
