Research and analysis of laser rapid forming process

  LRP is a new manufacturing technology integrating advanced technologies such as CAD, CAM, CNC, laser, precision servo drive and new materials.Compared with traditional manufacturing methods: the original form of replication and interchangeability;The manufacturing process has nothing to do with the geometrical shape of the original shape;The processing cycle is short and the cost is low, the general manufacturing cost is reduced by 50% and the processing cycle is shortened by more than 70%.Highly technical integration, realize design and manufacturing integration.
  The recent development of LPR mainly includes: the technique of three-dimensional photoforming (SLA);Selective laser sintering (SLS) technology;Laser cladding (LCF) technology;Laser near-form (LENS) technology;Laser wafer lamination manufacturing (LOM) technology;Laser induced thermal stress forming (LF) technology and 3d printing technology.
  SLA is also called light curing rapid prototyping technology, its principle is computer controlled laser beam on the surface of the photosensitive resin as raw material for point by point scanning, the scanned area of the thin layer of resin (about 10 points a few millimeters) produce light of polymerization and curing, a thin layer of formed parts.My workbench is a thick layer of distance, so as to cure good resin on the surface and then apply a layer of new liquid resin, on to the next layer scanning and processing, so repeatedly, until the prototype manufacturing.
  The light polymerization reaction is based on the effect of light rather than heat, so a low power laser source is needed at work.If you want to know more or have special requirements, can be directly send samples to Wan Ting laser marking machine laser processing samples, other models include optical fiber laser marking machine, a portable laser marking machine, metal laser marking machine, CO2 laser marking machine, CO2 laser marking machine, CO2 laser marking machine, portable pipeline laser printing machines, bar code qr code marking machine, date of production batch number serial number laser marking machine, laser equipment.
  In addition, because there is no thermal diffusion, and the chain reaction can be well controlled, can guarantee the polymerization will not occur in the laser spot, and high machining accuracy, good surface quality, the utilization rate of close to 100% of raw materials, to produce the parts of complex shape, fine, high efficiency.For larger parts, it can be made by using the first block forming and bonding.
