The photoconductive rod of 360 degrees rotation can avoid infection with high temperature. 1100mw/cm2 of its light intensity. It needs just 10s to solidify the 4mm materials. The wavelength range is from 420nm to 480nm, which can solidify all presently photosensitive material. Use the rechargeable li-ion battery. The total operation times from 20s x 250 times Superconductor will radiate more than 100.000 times for several years without changing the bulbs. Made of aluminum alloy frames with extremely light weight, only 150g. Quiet design without the fans and with the cold light source. Can choose the different color.
