3D Printing Method Based On Trough Polymerization Green Laser Pointer
The high-resolution 3D printing method is based on the grooved polymer green laser pointer technology. Technology also uses near-infrared light, but with lower intensity. In order to take full advantage of the potential of light and eliminate some of the disadvantages of femtosecond lasers, scientists have written a new article on the formulation of materials. Upconverted nanoparticles are composed of two or more photons. These photons combine and emit more energy when exposed to a light source. In the research, scientists added up-converted nanoparticles to a photo-curable resin mixture. The application of up-conversion is concentrated in the field of biological imaging, according to the definition of the field of biological imaging. Upconversion is the conversion of two or more low-energy pumped photons into one high-energy. A green laser pointer that outputs photons is a nonlinear optical process.
It was first discovered in the mid-1960s. Because the green laser pointer had a very low quantum yield and no high-energy excitation source at the time, it was not noticed. Later, with the widespread use of lasers, it became a focus of research. In the field of biological imaging, the components of the up-converted nanoparticles are an inorganic matrix and rare-earth doped ions. The doped ions include a luminescent center and a sensitizer. Under NIR near infrared light. Upconverted nanoparticles absorb near-infrared light green laser pointer and emit UV light. The resin is thus cured with the three-dimensional accuracy of the voxels.
