SLA：SLA(Stereo lithography) stereo lithography technology, also known as the process is mechanical, laser, photochemical, software, crystallization control technology.
Vowin has 2 sets of Printing Machines. One is Objet30 imported from Israel,another is made in China. The biggest printing size is 600mm*600mm*400mm.
Surface finish:painting/laser etching/silk-screen and so on.
For small complicated parts, SLA will be the first choice.It could machine the whole part with 1 piece and have tight tolerance.
SLS：Selective laser sintering is using laser selective sintering of layered solid powder, and the curing layer overlap to form a desired shape of the sintered parts.
Surface finish: not adhesive with oil(painting) & glue,cleaning the surface
The materials need to withstand high temperature up to 100°or so.
