to the geometry information of the parts produced by CAD, the 3D numerical control forming system is

controlled by the laser beam.

SLSSLS the main materials used in the actual production process include: nylon 11, nylon 12, ceramic, wax and

according to different needs of the aboveMaterials were modified materials. Such as adding aluminum powder to 

make the material have a certain metal andeffect; the addition of fiber material to increase the hardness of 

the material, etc.

SLA laser forming characteristics:
1, the processing precision is high, can reach 0.1mm;
2, the surface is smooth, the quality is good, easy postprocessing, the cycle is short;
3, can produce very fine details, and thin-walled structure complex molding products such as hollow parts,

irregular surface, many CNC Shouban processing details can be processed
4, material selection of limited, must be a photosensitive resin;
5, the strength of the material is a bit poor, not easy to carry out many times, and hit the screw.

SLA process SLS process
Processing maximum size 550mm*450mm*450mm 600mm*500mm*450mm
Material properties
Uses the product structure is complex, the strength is not high, the strength toughness is high, the high

temperature resistant product, the material widespread
