3D printers are very useful in theory, but in practice unwieldy, unwieldy devices. That changes with this new printer. Startup OLO uses a smartphone to generate the light that hardens a photosensitive resin in the right places.
An interesting feature is that it is possible to share a design with another OLO3D user.
The OLO3D is not suitable for impatient people. A printout can easily take a few hours. You can't use your smartphone all that time. So hell for the average hip smartphone user.
