    Well, kind of. Its main use is to customize existing stuff, like printing pictures on a phone case, custom key caps, and such. I don’t know what the ink is made of - I’m guessing a UV curable binder and pigments? Or liquid gold, judging from the price…


  • Creating nano-PeLEDs, however, was no simple task. Perovskite materials are notoriously fragile and susceptible to damage during conventional photolithographic processes used to pattern LED displays. To overcome this, the research team developed a novel fabrication method involving lithographically patterned windows in an insulating layer. This technique protects the delicate perovskite material while preserving high image quality.

    They’re creating a whole display panel, not individual components.
















  • I looked into it, but it covers a different use case. It’s based on photogrammetry. For reverse engineering, you always need at least one measurement to scale the mesh. Also, you cannot scan anything bigger than the enclosed space within the scanner.

    The einstar actually measures depth, so I can get measurements even if I scan the object from just one side. It stitches the measured points together by overlapping features, so it theoretically can scan infinitely large objects.

    A big reason why I wanted an All-in-one 3D scanner was because I want to reverse engineer objects I see “in the wild” and in museums. The staff there might not appreciate it when I put a ruler on their stuff.
