Combining laser engraving with 3D printing creates unique, customizable items quickly and inexpensively. Creative projects ...

A quirk in scientific 3D modeling has led to the discovery that laser light can — under the right circumstances — cast its own shadow. The finding challenges our current understanding of what ...

A camera captures images of the patterns of light and dark on the model, math happens, and 3d data is spit out of a computer. [Jas] found a Microvision SHOWWX laser pico projector on Woot.

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Engineers at Duke University have successfully manipulated laser beams to create intricate 3D patterns known as 'optical ...

Scientists have demonstrated a sort of holographic strip that splits a single laser beam into five bespoke beams that create an optical knot. The work shows that optical knots could be used as a ...

Laser-based 3D printing, according to Vilnius University. The work highlights Lithuania’s growing prominence in high-tech ...

By 2024, 3D laser scanner sales are expected to reach USD 1,844.5 million worldwide, driven by a 6.6% compound annual growth ...

3D-printed delta-bot motion control platform that’s capable of positioning samples with sub-micron precision. Above the stage are the deceptively simple optics, with a laser diode light source ...

“The technology uses less expensive light sources as simple as a laser pointer ... and health care. Femtosecond laser two-photon polymerization is widely used for 3D nanostructure fabrication.
