SLA/SLS 3D Printing
Detailed description

SLA technology is based on the polymerization principle of liquid photocurable resin, while exposed to certain wave length and strength ultraviolet ray, this liquid material will rapidly make polymerization reaction, at that time, the number of molecule will drastically increase, via these complicate procedures, liquid material is turned into solid material.SLA technology relys on the computer and material technology. Moreover, instead of the traditional way of mechanical work, laser moulding technology, according to the component geometry information which generates from CAD, dominates three-dimensional numeric control molding system. Thus, the laser beam will accumulate material into the parts, by this way, there is no need to design and mechanical process the mould or professional tools, which obtain striking upsurge of product efficiency and manufacture flexibility. Here are some characteristics of SLA rapid prototyping:

 

 1): the high accuracy of manufacture, which could be 0.1mm

 

 2): could make complete and intensive structure production, especially apply to the small            electrical products,toys, crafts, ornaments, etc

 

 3): produce components quickly,and make 0.1-0.15mm hierarchical scan

 

 4): high quality of the appearance,produce delicate detail thin-wall structure,which is            contribute to post-treatment.

 

 5): the integrity and precision of product construction,some elaborate parts are able to be          manufactured that CNC palm cant deal with,in a certain degree,ease the work of post-            treatment.

 

 6): the disadvantages of SLA rapid prototyping,the material of photocurable resin is reversely          unitary while the laser molding is adopted.Whats more,the tenacity and strength of SLA          palm isnt as good as CNC palm,and the undercut area is easy to be broken.
