Solidification light can aggregate into solid model with photosensitive resin, and the photosensitive resin not contacted with light then keeps liquid, thus exists
Successively production needs the object printed in the print platform side corresponding with resin storage tank.
When irradiating printed material due to the use of same light source, scattering state is presented in the light energy penetrated, therefore can be solid
The wavelength for changing light fluctuates, and after being irradiated on printed material, partially cured light does not reach the resin of photosensitive resin
Cured wavelength will then influence molding Mass accuracy and molding efficiency, for example cured light wave a length of 405 is received
Rice, the wavelength that actual light source has part light during send out change and are in 390 rans, this part light wave will
Influence Forming Quality.Such as partially cured or retardation of curing.
