Researchers from the Massachusetts Institute of Technology and the University of Texas at Austin showcased the first chip based resin 3D printer. Their concept verification tool consists of a millimeter sized photon chip that emits a programmable beam of light into resin holes, which solidify into a solid structure when exposed to light.The prototype processor does not have mobile components, but ...
Application backgroundLaser swing welding technology was born out of the urgent demand for welding quality and efficiency in modern manufacturing industry. Traditional welding technology has shortcomings in precision, strength, and complex structures, which has led to the rapid application of laser welding in various fields. However, it still has defects such as pores and cracks, and has limitatio...
The research from the University of West Virginia has been rewarded, as debris scattered in planetary orbits that pose a threat to spacecraft and satellites may be pushed away from potential collision paths by a coordinated space laser network.Hang Woon Lee, director of the Space Systems Operations Research Laboratory at the University of West Virginia, said that artificial debris dumps, including...
Scientists at the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers say this approach shows great promise; Although the experiment is still in its early stages, these quantum dots are already as efficient as existing conventional methods.These points could one day form the basis of infrared lasers, as well as small and inexpensive ...
