SLA rapid prototyping is a discrete layered, layer by layer stacking technology, the direct use of three-dimensional computer data is implemented as a prototype of the product, the more mature laser technology both SLA and SLS rapid prototyping, which the SLA the main material for the photosensitive resin.
A smooth surface, and good quality. Forming high precision, and accuracy of 0.1mm; Can be made very fine details and molding of thin-walled structures, high precision, easy post-processing. Processing cycle is short, usually it is three days.
The disadvantage of SLA:
1 selectable types of materials is limited, and must be a photosensitive resin. 2 processing strength of the material is a bit weak, can not be repeated disassembly and hit the screw.
