Additive manufacturing technology is a high-tech manufacturing technology based on material addition method, which is considered to be a major achievement in the manufacturing field in the past 20 years. The traditional manufacturing technology is widely used in the electronics industry, and the technology is relatively mature, but it can only be processed in a plane, with serious pollution and limited limitations. The development of laser advanced additive manufacturing technology not only effectively and accurately transforms design ideas into entities, but also provides a high-efficiency and low-cost means of implementation.
The laser additive manufacturing technology is based on discrete/superimposed. The part model is first divided into a series of sheets, and then these sheets are sequentially produced by 2D manufacturing process, and stacked layer by layer to become the final 3D parts. The laser additive manufacturing technology is used in the field of electronic manufacturing. Because the volume of electronic and electrical products is usually small, the integration is high, and the line/pitch resolution is usually in the micro-nano level. Therefore, this additive manufacturing technology is also called “ Laser micro-additive manufacturing technology.
This technology breaks through the limitations of the traditional “removal” processing method, so it has the advantages of no mold, material saving, short manufacturing cycle, and easy manufacturing of 3D-multi-layer complex structural parts. It is remarkable in single piece, small batch and mass production. Cost and efficiency advantages.
