The core of photosensitive resin 3D printer: Ruifengheng nanosecond ultraviolet laser

Today, the editor of Ruifengheng Nanosecond UV Laser will introduce to you an application of our product-photosensitive resin 3D printing.

 

The photosensitive resin, namely the UV resin, is composed of polymer monomers and prepolymers. Under the irradiation of a certain wavelength of ultraviolet light, it will cause a polymerization reaction and change from a liquid state to a solid state. Because of this characteristic, photosensitive resin is widely used in 3D printing and molding. Many 3D printing molding, such as DLP desktop machines, SLA rapid prototyping equipment, mostly use this material.

 

Photosensitive resin has high light sensitivity, which makes it particularly picky about the ultraviolet light used to cure it. It requires ultraviolet light whose parameters such as wavelength and pulse are stabilized 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 for industrial manufacturing. Until the past ten years, some laser companies have developed and produced cost-effective 3D printing lasers that can be used in industrial manufacturing and can generate production profits.

 

Shenzhen Ruifengheng is one of them. After 12 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 lasers, which can provide high precision laser manufacturing industries such as photosensitive resin 3D printing. Quality laser.

 

In the application of photosensitive resin 3D printing, our Expert Ⅱ 355nm ultraviolet laser has been highly recognized by manufacturers and users: very stable and long life! Next, let's look at a set of parameters with the editor to see how outstanding the Ruifengheng Expert II 355nm UV laser is.

 

Expert Ⅱ 355 series ultraviolet 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 resin, thereby ensuring the accuracy of the 3D printing process.

 

Such excellent light quality is the endeavor of Ruifengheng Company for many years: the doctoral-level R&D team independently develops the power control system, which can update the power control system function modules in time, and improve the function modules according to the needs of the laser. Debug the overall stability of the entire laser processing system of power supply + laser head + cooling system to ensure that the entire laser system exerts its ideal performance; the company continues to improve the quality management system, from procurement-quality inspection before production-strict assembly process-finished product Testing-warehousing quality inspection-pre-delivery testing-after-sales service, each level is checked, and the quality is continuously improved. Therefore, the Ruifengheng laser with both performance and service life is available.

 

12 years of deep cultivation of the brand, excellence, and pursuit of excellence have made Ruifengheng a first-class enterprise that can manufacture first-class lasers and provide first-class laser technology and services.
