Many hobbyists and hackerspaces have the $500 Chinese 40W lasercutters which most of us know are about as successful at etching metals as a featherduster is at drilling. [Frankie] and [Bryan] have ...

We developed an efficient fabrication method of high-quality concave microarrays on fused silica substrates based on temporal shaping of femtosecond (fs) laser pulses. This method involves exposures ...

A team from Lawrence Livermore National Laboratory, Stanford University and the University of Pennsylvania introduced a novel wet chemical etching process that modifies the surface of conventional ...

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.

Researchers demonstrate how laser etching of metallic surfaces creates the ''perfect solar energy absorber.'' This not only enhances energy absorption from sunlight, but also reduces heat dissipation ...

Laser engraving, using a high-powered laser to leave permanent etchings on an object, can be done by burning the object or by inducing a chemical reaction that leaves a residue. Either way, it's ...

Due to their accuracy, speed, and versatility in working with different materials, laser engraving machines have gained traction from industries such as small firms and creative artisans. However, ...

Get set to design your own tyre patterns. That’s the future of tyre technology as seen by Kumho, and although individual design-your-own tyre tread is probably some way away yet, it’s quite feasible ...

When it comes to machining, the material that springs to mind is likely to be aluminum, steel, or plastic. We don’t necessarily think of glass as a material suitable for machining, at least not in the ...
