When making prototype model, often use laser to complete quickly.Using the principle of
discrete layering, and then accumulated,directly using the three-dimensional data to show
the product prototype,now the skilled laser rapid prototyping technology mainly including
SLA and SLS.
The former adopt RS350 equipment, it is one of the world's best technology, material is
photosensitive resin.By making use of the characteristic it would concrete if exposed to
the uv light, the laser which controlled by the computer scan the photosensitive resin to
the curing tank slowly, make it condenses and curing, the surface of each curing layer
is gained by the three-dimensional model software discrete layering, until get the whole
product components prototype. After forming ,the color of the material is white, no demands
to the product's structure, can be made into very fine details and thin wall structure, and the
accuracy is very high, very easy for post-processing.
The latter adopt AFS - 450 equipment, make use of the local laser sintering, the beams
will through the window to scan the nylon powder density with a certain speed and energy
under computer control.The powder will form to layer with the thickness after the beam
scanned, the formation of the second layer is sintered on the first one,keep repeating,
then a three dimensional physical prototype is finished .The material is nylon powder,
the strength and toughness of finished product is very good, is appropriate to test the
assembly structure.
