The accuracy of two processing methods in
rapid prototyping are relatively large difference.
The first one is stereolithography. Selective laser sintering process has a wide range of
applications and attractive,because it can cake many materials,even some ceramic layer
.This features can cover some shortcomings, for example,the accuracy is not high,the surface
is rough.
This method fit for some high-grade handicraft,or some product with high accuracy and smooth
surface.
The second one is light curing laser powder sintering molding.If some general large products
with low accuracy and low price,can adopt this method.
