Olo features a beautiful and portable design that is easy to use at a fraction of the cost of any other 3D printer on the market. Olo is made of only 7 plastic parts, one chip, and one motor.It introduces a completely new line of materials called Daylight Resins, which harden under the white light of a smartphone screen. Its case was specifically designed to filter out all harmful external light to maximize the precision of the print, which can reach the incredible 42 micron resolution.

All of the software processing is handled by the OLO app, available for iOS, Android, and Windows. There is no manual levelling or calibration required, the company said. Once an object has been loaded and printing commenced, the app instructs the smartphone to light up specific pixels for a set amount of time. Resin affected by the light transforms from a goo-like substance into hardened material, they said.
Basically, 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 polarized 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 traveling straight upward. So as your phone’s screen beams light up into the reservoir, the directed light causes a layer of resin to harden onto the build plate, which slowly moves upward as each new layer is created. It’s basically a tiny DLP printer that uses your phone’s screen instead of a projector — which is absolutely brilliant, because doing so replaces the single most expensive part of a stereolithography printer with something cheap and very common.
