What is SLA Laser Rapid prototyping?

sla Laser Rapid prototyping is a more common prototype processing method, which is' Stereo photography Appearance'The abbreviation, that is, the three-dimensional light curing molding method.

its working principle is as follows: first, a 3D solid model is designed through CAD, and the model is sliced by discrete programs, design the scan path and the generated data will accurately control the movement of the laser scanner and the lift table; The laser beam passes through the scanner controlled by the numerical control device and shines on the surface of the liquid photosensitive resin according to the designed scanning path, so that a layer of resin in a specific area of the surface is cured, and when the layer is processed, generate a section of the part; Then the lift table drops a certain distance, the curing layer is covered with another layer of liquid resin, and then the second layer is scanned. The second curing layer is firmly bonded to the previous curing layer, the 3D workpiece prototype is superimposed layer by layer.

The model appearance made by sla Laser Rapid prototyping will have supporting materials, and the role of supporting materials is to maintain the shape of the prototype model, therefore, the sla prototype seen after printing is relatively rough, and it needs to be polished and sprayed to meet the customer's requirements.

at present, many sla devices can only print prototypes of photosensitive resin and abs materials, however, in addition to printing these two materials, the advanced sla equipment can also print 17 kinds of materials such as transparent materials and nylon materials, which can even withstand high temperature of 180 degrees and are very good. I believe that sla Laser Rapid prototyping will replace CNC machining and become the mainstream of prototype processing industry in the future.
