3W and 5W UV lasers for 3D printing

First of all, the ultraviolet laser is a high-energy laser beam with a wavelength range of around 355nm and has the characteristics of high precision, high speed and high efficiency. In the field of 3D printing, UV lasers are mainly used to solidify liquid photosensitive resin to form a solid laminated structure. Among them, 3W and 5W ultraviolet lasers are two common power specifications, which refer to the laser output power of 3 watts and 5 watts respectively.

The application of 3W UV laser is mainly reflected in the balance between printing speed and printing accuracy. Its lower output power makes the curing speed of photosensitive resin slower, but it can effectively avoid overheating or deformation during the printing process, improving printing accuracy and quality. Therefore, for some 3D printing applications that require high precision, such as medical devices, microelectronics and other fields, 3W UV lasers are a good choice.


In contrast, 5W UV lasers have higher output power and can complete large-area curing operations in a short time. This means that the use of 5W UV lasers can greatly improve the production efficiency of 3D printing, and is especially suitable for applications that require rapid manufacturing of large objects, such as automobile manufacturing, aerospace and other fields. At the same time, due to its high energy density, the 5W ultraviolet laser can also process some difficult-to-process materials, further expanding its application scope.


In short, both 3W and 5W UV lasers have broad application prospects in the field of 3D printing. Different power specifications correspond to different application requirements. Choosing the appropriate UV laser can help improve the efficiency and accuracy of 3D printing, thereby providing better solutions for various fields.

S9-Y series solid state pulsed UV laser is ultra compact. The whole part of power supply is integrated into the laser head. This makes the size of the laser more smaller, and the integration into a system more easier and convenient. S9-Y series is of short pulse width(<12ns@30k),superior beam quality(M²<1.2) and perfect laser sport quality(beam circularity>90%).
