Advantage of SLA

1 Spot diameter of ultraviolet laser < 0.15 mm by focusing;

2 High precision of molding , exquisite structure is available (such as ring and artware );

3 Making any parts with complex structure (such as hollow parts);

4 High surface finish (surface Ra < 0.1 microns);

5 Molding process is highly automated and post-treatment is easy.qu(point support, easy to remove);

6 Material utilization is above 95%.

SLA

HK PRECISE PROTOTYPE adopt SLA  (stereolithography)technology  (it is a kind of 3D rapid prototype process which is mature ,deepened study and widely used in the world )which control laser beam by computer to scan the surface of  prototype made from photosensitive resin (ABS/transparent) point by point. Thin layer of resin (about 0.1 mm)scanned will generate light polymerization then curing and  become a thin layer of prototype.Move down the workbench to a thin layer which is with same thickness so that  the surface of the resin which is well solidified can lay another layer of liquid to go on the scanning of next layer,repeating this process until the prototype finished. SLA laser printing is suitable for prototype whose structure is complicated and requirement  for workmanship is  exquisite, it can also process much details quickly which is out of CNC reach thus reducing the workload greatly.

SLS

selective laser sintering referred to as SLS parts is a molding system which uses infrared laser to sinter powder material(nylon, nylon fiber, nylon carbon fiber, nylon aluminum powder, PS material) directly.

Analysis of SLS

According to the statistical analysis, the latest F - 35 Lightening II aircraft has 1600 parts made of SLS prototype process quickly . EADS, parent company of Airbus,has already began to study 3D printing technology to make aircraft , as it can not only reduce cost, but also make every part light about 65% compared with traditional manufacturing method .

Advantage of SLS

1,The performance of plastic parts and plastic injection parts is the same and can be used as products directly.

2, SLS prototype powder sintering molding process is with high speed which can up to 14 mm per hour.

3, There is no support structure and powder materials can be recycled which can save costs as well as environmentally friendly .
