SLA rapid prototyping (RapidPrototyping) is also known as the rapid prototyping technology, the main raw material is photosensitive resin is CAD, CAM, CNC, laser, precision servo
drive and new materials and other advanced technology integration of a new manufacturing technology.
SLA (Prototyping Rapid) CAD, CAM, CNC laser, precision servo drive and new materials and other advanced technology integration of a new manufacturing technology, SLA laser
rapid prototyping principle is a computer controlled laser beam on the photosensitive resin as raw material surface to point by point scanning, scanning area of the resin layer
(about a few mm) produced by light polymerization reaction and curing, forming part of a thin layer. The working table moves down a layer of thickness, so that the cured
resin surface and then deposited on a new layer of liquid resin, the next layer of scanning processing, so repeated, until the entire prototype is finished. Because the light
polymerization reaction is based on the role of light and is not based on the role of heat, it is necessary to work with a low power laser source. In addition, because there
is no heat diffusion, coupled with the chain reaction can be well controlled, can ensure that the polymerization reaction does not occur outside the laser point, so the processing
precision, good surface quality, the use of raw materials is close to 100%, can produce complex, fine parts, high efficiency. For the large size of the parts, it can be used to form
the first sub block and then the bonding method of production.
Characteristics of SLA rapid prototyping:
1, the processing precision is high, the product general can reach 0.1mm/100mm by SLA laser rapid prototyping;
2, can create complex shapes (such as hollow parts), especially fine (such as jewelry, handicrafts, etc.), suitable for mobile phones, radio, radio, mouse and other sophisticated
parts and toys and high-tech electronics industry, home appliances shell or model, motorcycle, car accessories or models, medical equipment, etc.;
3, manufacturing parts fast, can be carried out 0.1 - 0.15mm scan;
4, good surface quality, can produce very fine details of the thin wall structure, postprocessing easily;
5, the processing in place, many CNC boxart processing to the details can processing, so as to reduce the processing workload.
6, SLA hand toughness than CNC scaffold, buckle located easily broken;
7, compared with the traditional manufacturing methods: the prototype of the replication, high exchange, manufacturing process and manufacturing prototype geometry has
nothing to do; processing cycle is short, cost is low, the general manufacturing cost is reduced by 70%, the processing cycle is shortened by more than 50%.
8, similar to traditional engineering plastics such as ABS, with certain viscosity of transparent or meters yellow liquid, make the workpiece is translucent or
beige, better strength, can assembly, self tapping screws, spray paint, silk screen, the disadvantage is not resistant to high temperature.
