Spreading the laser beam's intensity out reduces the temperature difference between sections of the part being printed. Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make ...

Laser engraving uses a powerful beam of light to create detailed designs on various materials. The laser works by vaporizing the surface layer, leaving behind precise and lasting marks or etchings.

In an effort to make a futuristic tractor beam, researchers have turned to the distant past to create a particle-trapping laser. It is not uncommon to hear about how ancient ideas have influenced the ...

Additive manufacturing is a key technology for industry that allows building structures by progressive addition of material, with complex geometries. One of the main techniques is the laser beam ...
