RFH 355nm nanosecond UV laser for 3D printer light curing


RFH 355nm ultraviolet laser products have been widely used in SLA process. Since 2007, RFH has been intensively working in the field of 3D rapid prototyping. With the spirit of craftsmanship, it has launched generations of UV lasers for SLA technology. The product series are rich and the stability is excellent. It provides a large number of UV lasers for domestic and foreign customers. The laser has been recognized by many customers.

The principle of SLA processing is mainly to use a laser with a specific wavelength and intensity to focus on the surface of the light-cured material, so that it solidifies from point to line and from line to surface in order to complete a layer of drawing operation, and then the lifting platform moves a layer in the vertical direction The height of the film, and then solidify another layer. In this way, the layers are superimposed to form a three-dimensional entity. How to control the wavelength and laser intensity is the key to the accuracy of the SLA process.


The RFH Expert Ⅱ 355nm UV laser has a laser wavelength of 354.7nm, a wide range of repetition frequency (single pulse to 200kHz), and superior beam quality (M2<1.2), which is strictly guaranteed in all frequency ranges; pulse width <20ns @30k, the heat affected zone is very small during processing, which is very suitable for SLA process production.


SLA technology is currently being developed to improve processing accuracy, and in the future there will be greater breakthroughs in the fields of biology, medicine, and microelectronics. With the continuous changes in the processing market, today's business owners and consumers have increasingly higher requirements for product processing technology. In such a challenging market background, solid-state ultraviolet lasers will help SLA technology continue to become more economical and easy to use.
