In addition, the RFH ultraviolet laser spot is small and concentrated, and the ultra-high energy beam only needs to run in an instant for printing production. In 3D printing, the RFH ultraviolet laser irradiates the liquid photosensitive resin with pulsed ultraviolet waves, and completes the final curing and molding with the help of the connected scanning galvanometer. Therefore, RFH is fully able to meet the needs of 3D printing customization, and helps enterprises to carry out mass production and individual customization in terms of precision, quality, speed and innovation.
