Mr. Ma from Hangzhou recently ordered RFH 5w and 10w UV lasers, hoping to have a greater breakthrough in 3D printing light curing technology. Compared with non-fiber lasers or CO2 lasers, the short-wavelength spot of ultraviolet lasers is longer, and it belongs to cold processing. It can use non-contact output to make 3D printing light-solid technology glow with new vitality.
