Description

technical field [0001] The invention relates to a powder laying device, in particular to a powder laying device for rapid prototyping. Background technique [0002] The main technical means of rapid prototyping manufacturing is 3D printing technology. Many of 3D printing technologies use powder as raw material, stacked in layers, and finally formed. This new type of rapid manufacturing technology can directly obtain molded parts of any shape without being affected by the complexity of the molded parts, providing a higher degree of freedom for the design, and compared with the previous processing technology, its processing cost is low, and the processing The speed is fast, especially suitable for experimental verification and small batch production in the early stage of research and development, and has broad application prospects. [0003] At this stage, all kinds of rapid manufacturing technologies using powder spreading devices have the following similar problems: [000...
