Mold cleaning: Mold plays a very important role in industrial production. Currently, there are over a thousand mold related enterprises in China, driving the related output value to nearly 10 billion yuan. Among them, mold cleaning is an essential step in mold production. Laser can achieve contactless cleaning of molds, which is very safe for the surface of the mold, ensuring its accuracy, and can...
The gravitational wave background was first detected in 2016. This was announced after the release of the first dataset by the European pulsar timing array. The second set of data has just been released, combined with the timed array of Indian pulsars, and both studies have confirmed the existence of the background. The latest theory seems to suggest that we are seeing a comprehensive signal of th...
Recently, researchers from Osaka University in Japan have developed the world's first compact, wavelength tunable blue semiconductor laser in a new study. This breakthrough paves the way for far ultraviolet light technology and brings enormous potential for applications such as virus inactivation and bacterial disinfection. The research results have been published in the journal Applied Physics Le...
Researchers from Columbia University in New York reported the latest research on reverse laser sintering of metal powders. The related achievements were published in Scientific Reports under the title "Invested laser sintering of metal powder".The researchers demonstrated the ability of reverse laser sintering technology to manufacture metal powder parts. Researchers first deposit a layer of coppe...
According to scientists at MIT, mathematical formulas developed by MIT researchers and other institutions can significantly improve the sustainability of 3D printing.Issues with 3D printing of plastics3D printers typically use mass-produced polymer powders to print parts, which are consistent and predictable, but also difficult to recycle.Other more environmentally friendly options also exist and ...
