Laser Rapid Prototyping (LRP) is a new manufacturing technology which integrates advanced technologies such as CAD, CAM, CNC, laser, precision servo drive and new materials. Compared with traditional manufacturing methods, it has the following advantages: high reproducibility and interchangeability of prototype; manufacturing process has nothing to do with the geometric shape of prototype; short processing cycle, low cost, 50% reduction of general manufacturing cost, 70% reduction of processing cycle; high technology integration, and integration of design and manufacturing.
Recent developments in LPR include: stereo optical forming (SLA), selective laser sintering (SLS), laser cladding forming (LCF), laser near-form (LENS), laser thin-sheet lamination manufacturing (LOM), laser induced thermal stress forming (LF) and three-dimensional printing technology.
SLA technology is also called photo-curing rapid prototyping technology. Its principle is that computer controlled laser beam scans the surface of sensitive resin point by point. The thin layer of resin in the scanned area (about ten millimeters) produces photopolymerization reaction and solidifies, forming a thin layer of parts. The workbench moves down a layer of thickness so that the cured resin surface can be coated with a new layer of liquid resin, and the next layer is scanned and processed repeatedly until the whole prototype is finished.
Because the photopolymerization reaction is based on the action of light rather than on the action of heat, only a low power laser source is needed. If you want to know more or have special needs, you can send samples directly to Wanting Laser Marking Machine Laser Company for processing. Other models include optical fiber laser marking machine, portable laser marking machine, metal laser marking machine, CO2 laser marking machine, CO2 laser marking machine, CO2 portable laser marking machine, pipeline laser. Laser equipment such as jet printer, bar code two-dimensional code marker, date serial number laser marker and so on.
In addition, because there is no thermal diffusion and the chain reaction can be well controlled, it can ensure that the polymerization reaction does not occur outside the laser point, so the processing accuracy is high, the surface quality is good, the utilization rate of raw materials is close to 100%, and the parts with complex shape and fine shape can be manufactured with high efficiency. For larger parts, the method of forming in blocks and then bonding can be used.
