This device can transform your smartphone into 3D printer
The device consists of three parts: A reservoir, which holds 400 cubic cm of printing volume; 100-gram bottles of coloured photopolymer resin to build your objects with; and a mechanised lid, under which the build plate and control electronics are tightly arranged.
First, you have to load a schematic of your object into the OLO mobile app (available for iOS, Android, and Windows) and then fit your smartphone into the base under the reservoir. A piece of polarised glass is installed into the base, which your phone’s touchscreen will be facing when set in place.
Once you place the lid on top and the printer starts going, the app makes your phone’s screen light up with a specific pattern. The polarised glass then takes all this light (which shines outwardly to give your phone a wider viewing angle) and redirects it so that all the photons are travelling straight upward.
