Russian Scientists Develop Based On Green Laser Pointer
Two-photon lithography is a 3D printing method. Unlike most green laser pointer 3D printing technologies. The resolution of 3D laser printing technology is limited by the size of the 3D printer's laser dots. Two-photon polymerization technology increases print resolution to incredible precision. This technology deserves further study in the fields of medical research, namely applications for drug delivery, tissue regeneration, chemistry and material synthesis. In two-photon lithography, however, femtosecond lasers are used to precisely cure resins. Not only is the point-to-point process time consuming. And the laser works at high intensity. Material can be damaged and the instrument is expensive.

Previous U.S. researchers announced in January 2018. A way to improve two-photon polymerization was found. Two-photon polymerization is a nanoscale 3D printing technology. Developed two-photon polymerization 3D printing technology to a level that can take into account both microscopic accuracy and large dimensions. Coincidentally, scientists from Russia are also actively promoting the research of two-photon lithography. In a study led by a research team at the Russian Academy of Sciences in Moscow. Researchers announced recently. They explored an "unprecedentedly effective" high-resolution 3D printing method. Some disadvantages associated with the existing green laser pointer technology can be eliminated.
No wonder the focused laser beam is used improperly. For this reason, high-quality units currently on the market use so-called infrared beam filters. The role of these safety mechanisms is actually to prevent the laser itself from emitting invisible light. This is important for all output power, but even more so for some combustion devices discovered today. This is because the beam is visible when using a visible laser, and reflections, experience, and potential unintentional exposure can be carefully avoided. This simple, inexpensive device that does not use cheap equipment is actually a bit dangerous when used at high power, indoors, and for long periods of time. Make sure that the laser system you are considering has an infrared filter to prevent unnecessary exposure.
