SLA is based on photosensitive resin as raw material, and the laser is controlled by computer to scan the surface of the liquid photosensitive resin point by point according to the section information of each layer of the part. The resin thin layer in the scanned area generates photopolymerization reaction and solidifies, forming a thin layer of the part. After the first layer is cured, the table is moved one layer thick, and a new layer of liquid resin is applied to the previously cured resin surface until the 3D solid model is obtained. This method has the advantages of fast forming speed, high automatization, nearly 100% material utilization, arbitrary complex shape, high dimensional precision and high strength. It is mainly used in the rapid forming of complex and high-precision fine workpiece.

FDM fused deposition molding

It is formed by extruding the thermoplastic material into semi-fused filament and discrete stacking. Its advantages are more types of forming materials, forming fast, forming parts of high strength, high precision. There is no chemical change in the forming process, the warping deformation of the parts is small, and the material life is long. Widely used in molding parts and small plastic parts with complex cavities and cavities

Selective laser sintering

After the photography is completed, the image information retained by the medium must be converted and re-read by the human eye. The specific method depends on the photosensitive means and medium characteristics. For film cameras, there are chemical processes such as fixing, developing and magnifying. For digital cameras, the images need to be processed by computers and then output by other electronic devices. In general, people use visible light to take pictures, the most commonly used is the camera. Depending on the scene and purpose, there are many categories of cameras.
