The Olo is made of seven plastic parts, one chip, and one battery-powered motor. It uses photopolymers called Daylight Resins which harden under the white light of a smartphone screen. Its case was designed to filter out all external light to maximise the precision of the print, which can reach the 42µm resolution.
Because its motors are battery-powered by four AA batteries, users can print anywhere, without needing to recharge and is claimed to last at least 100 prints.
Olo is compatible with any device: Apple, Android or Windows, and larger smartphones, like the iPhone 6+ are also compatible. An object is loaded into the Olo mobile app, with the smartphone positioned into the base of the printer. When the smartphone is placed underneath the glass surface of the resin container the app lights up the screen in a specific manner. The light from the smartphone cures the resin. As the light moves upward and hardens the resin, the object is built layer by layer, resulting in a high-resolution 3D object.
