The intricate patterns, randomly chosen dots, symbols, QR codes, geometric prisms, and even a bird, appear purple in the ...

Just when you think you’ve learned all the latest 3D printing tricks, [TenTech] shows up with an update to their Fuzzyficator post-processing script. This time, the GPL v3 licensed program ha… ...

A 3D-printed goblet made with gold nanoparticles can look either purple or brown depending on the light, and its colour will never fade. Close.

Liao and the team used a green 532-nanometer (nm)-wavelength laser to inscribe 3D patterns into tiny slabs of the doped glass. The intricate patterns, randomly chosen dots, symbols, QR codes, ...
