SLA prototype first appeared in the last century 80’s, when the CNC machining technology is not mature enough, so SLA prototype in the product development is widely used, but because of its material is photosensitive resin, not hard enough, so there are some limitations.
Due to the increasing demand for materials at an early stage of new product development, new rapid prototyping techniques have emerged, which is the SLS prototype, which is a powder sintering technology that produces very strong prototype parts, such as: nylon materials, and gets a lot of designers of interesting. This is all early 3D printing technology.
With the continuous development of industrial technology, 3D printing technology has been integrated into the ordinary people’s life and work, not only limited to the rapid manufacturing industry.
