RFH 355nm Laser source applied to photosensitive resin 3D printing

Today, the editor of RFH 355nm Laser source will introduce to you an application of our products - photosensitive resin 3D printing.

UV laser source curing SLA 3D printing

Photosensitive resin, that is, UV resin, is composed of polymer monomers and prepolymers. Under the irradiation of ultraviolet light of a certain wavelength, it will cause a polymerization reaction and change from liquid to solidified. Because of this feature, photosensitive resins are widely used in 3D printing. Many 3D printing moldings, such as DLP desktop machines and SLA rapid prototyping equipment, mostly use this material.

Photosensitive resins are highly photosensitivity, a characteristic that makes them particularly picky about the UV light used to cure them. It requires ultraviolet light whose wavelength, pulse and other parameters are stable within a certain range to successfully complete the preset curing. In the past, this kind of laser was very expensive, which is one of the reasons why the photosensitive resin 3D printing industry has not been developed and applied to industrial manufacturing. Until the past ten years, some laser companies have developed and produced cost-effective 3D printing lasers that can be applied to industrial manufacturing and can generate production profits.

Shenzhen RFH is one of them. After 16 years of research and development technology precipitation, the company currently has a complete product line including water-cooled, air-cooled or all-in-one lasers, intracavity frequency doubling and extracavity frequency doubling series lasers, which can provide high-quality lasers for precision laser manufacturing industries such as photosensitive resin 3D printing. quality lasers.

In the application of photosensitive resin 3D printing, our S9nm UV laser has been highly recognized by manufacturers and users: it is very stable and has a long life! Next, follow the editor to look at a set of parameters to see how excellent the RFH S9 UV laser is.

S9 series UV laser pulse width <14ns@30K, spot ellipticity >90%, beam quality M2<1.2, strictly guaranteed in all frequency ranges. These parameters ensure the critical light quality required for 3D printing in photosensitive resins, thus ensuring the precision of the 3D printing process.

Such excellent optical quality is the effort of RFH for many years: the Ph. + The overall stability of the complete laser processing system of the laser head + cooling system ensures the ideal performance of the complete laser system; the company continues to improve the quality management system, from procurement-pre-production quality control-rigorous assembly process-finished product testing- Incoming quality inspection-pre-delivery inspection-after-sales service, checks at all levels, and continuously improve quality. Therefore, there are RFH lasers with both performance and service life.

16 years of brand cultivation, excellence, and excellence have made RFH a first-class enterprise that can manufacture first-class lasers and provide first-class laser technology and services.
