Expert III 355 series UV laser can be used for industrial sla 3d printing, developed and produced by RFH, covers 10w-15w in laser power with short pulse width (<20ns@40K) ,superior beam quality (M²<1.2) and perfect laser spot quality (beam circularity >90%). 

RFH has developed a special supporting SLA light-curing 3D printer in addition to the already mature high-power ultraviolet laser. The 3D printer, which uses a UV laser and a liquid UV-cured photopolymer called "photoresin" to print parts, provides additional services to customers.

RFH UV laser is currently the most commonly used UV laser source for SLA 3D printers on the market. Some RFH UV lasers can be selected with multiple frequencies, which can meet the curing needs of different resins to the greatest extent.

3w 5w UV Laser Resin for SLA 3D Printers Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved  

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.

RFH's 3w-10w UV laser has recently made a new attempt in 3D printing, which is to upgrade the UV laser processing technology, so as to achieve high-speed, high-precision light curing effect. The RFH ultraviolet laser adopts non-contact production, which can use the direct light of the spot to deliver very high energy to the resin material, and convert it from light energy into heat energy, so as to make the resin solid-state.

UV laser cold sources are an essential component in SLA 3D printing technology. They provide the necessary energy to solidify liquid resin into a solid object layer by layer.  

First, the basic principle of ultraviolet laser   Ultraviolet lasers use high-energy short-pulse lasers to perform fine processing on the surface of materials. Its advantages are high precision, small thermal influence, and good processing quality.

Recently, Estonian customers purchased 3W and 5W UV laser light sources for 3D printing.
