RFH 355nm diode pumped solid state (DPSS) laser for SLA light curing 3D printing

The source of the powerful heart of SLA photocuring 3D printer: the superior beam quality of RFH UV laser

For point-to-line, line-to-surface 3D printing molding process, RFH UV laser is indispensable!

SLA, that is, stereolithography, is a widely used and very important one of several 3D printing technology molding processes that are currently widely used. It has a wide range of applications in aviation, automotive, microelectronics, medical and other industries.

The principle of SLA light curing is to use a specific intensity of laser focus to irradiate the surface of the light curing material (liquid polymer), so that it can complete the printing work on one layer from point to line, line to surface, and then proceed after one layer is completed. The next layer is stacked layer by layer to form a three-dimensional solid product. There are three technical difficulties: light-curing materials, light-curing systems and operating software systems. To complete an SLA project, the three are indispensable, especially the light curing system, which must be stable and fine enough.

At present, the industry mainly uses ultraviolet lasers known as "cold processing" as SLA light curing systems. The 3W-5W 355nm diode pumped solid state (DPSS) laser developed and produced by RFH Laser is such a high-quality UV laser that can be used for SLA photocuring.

RFH 355nm diode pumped solid state (DPSS) laser, short pulse width (<14ns@30K), superior beam quality (M2<1.2), strictly guaranteed in all frequency ranges, perfect spot characteristics (spot ellipticity>90% ), can provide stable curing light for SLA with very high process requirements, and support efficient and high-quality completion of point-to-line, and then to surface, layer-by-layer processing.

The high quality of RFH 355nm diode pumped solid state (DPSS) laser has multiple guarantees:

1. Quality assurance of product parts procurement

The core components of RFH laser pump and Q switch are all imported brands, and the components cooperate with domestic first-line brand suppliers to ensure the quality of each component from the source of the material procurement ecological chain, which is a confidence guarantee for users.

2. Strict quality management system mechanism guarantee

RFH lasers are strictly controlled at all levels from procurement, pre-production quality inspection and control, to assembly, finished product testing, warehousing quality inspection, and then to pre-delivery inspection to ensure stable quality and consistency between equipment parameters and actual operating parameters. Only with high-quality laser products, users are well-known.

3. Technical guarantee of doctoral team

RFH has a top laser research and development team composed of professors and doctors from Tsinghua University. The team independently develops a laser-specific power supply control system and the overall stable operation of the entire laser system to ensure stable quality under harsh conditions. The team has obtained 10 patent certificates issued by the state, 14 computer software copyright certificates, won the "National High-tech Enterprise", "Shenzhen High-tech Enterprise", "Software Enterprise Certification" and other certificates, and was awarded by Guangdong Province 3D Printing Industry Innovation The alliance and the Guangdong Laser Industry Association are appointed as the governing units.

After 16 years of hard work, RFH Laser has won high recognition from users from all walks of life at home and abroad, and established an excellent brand image.
