Here is OLO, a mobile 3D printer proposed for only $99! This highly innovative miniature SLA 3D printer, working with liquid resin, is using the screen of your smartphone and bright flashes to freeze the special resin, that cure and quickly harden when exposed to specific light spectrums. OLO goes even further by providing a dedicated app, which allows you to send objects to print in 3D, as you send texts and photos. The mobile SLA 3D printer OLO is being funded on Kickstarter, where it has already collected more than $ 1.7 million! A nice project to keep in mind, and a new step towards the democratization of 3D printers!
