SLA 3D printer (stereolithography).
RP technology
Rapid Prototyping (RP) is a new manufacturing technology that was first introduced from the United States in the late 1980s. It integrates modern scientific and technological achievements such as CAD technology, numerical control technology, laser technology and material technology, and is an important part of advanced manufacturing technology. Unlike traditional cutting methods, rapid prototyping uses a forming mechanism in which layered materials are superimposed to machine a three-dimensional part prototype. Firstly, the layering software slices the CAD geometry of the part according to a certain layer thickness, and obtains a series of contour information. The forming head of the rapid prototyping machine is controlled by the control system according to the two-dimensional contour information. Solidified or cut to form thin layers of various sections and automatically superimposed into three-dimensional entities.
SLA, The domestic name is stereolithography, also known as laser curing rapid prototyping. The principle is: the laser is focused onto the surface of the liquid photosensitive resin and scanned according to the cross-sectional shape of the part, so that it is selectively cured, from point to line to the surface, to complete the curing of one layer, and then the lifting platform is lowered by one layer thickness and recoated with a new layer a resin and cured by laser until the whole solid model is formed.
Advantage of SLA technology:
Currently it is the fastest plastic RP 3D printer
Accuracy is 10 times better than FDM 3D plastic printer, max accuracy can reach 0.05mm
Compatible material is very cost-effective, 10% of the price of DLP or small SLA, which highly reduce the cost of each RP part, esp. the part with large volume.
Build volume is large, as mentioned above.
Available build volume from Shanghai Digital Manufacturing Co., Ltd:
Will be launched by May, 2020.
Lorge volume plastic prototype.
