3D Printering: Smartphone Resin Printers Actually Work

Last spring, the world saw something amazing. It was a device that would revolutionize the planet, save the world, and turn your smartphone into a 3D printer. Kickstarters aren’t known for selling themselves short. I speak, of course, of the OLO 3D printer, later renamed the ONO 3D printer, ostensibly because of a trademark dispute.

While filament-based 3D printers are extremely capable and slicing software is only getting better, resin-based printers are able to produce prints of nearly unparalleled quality. If you want high-resolution objects and fine detail, a resin printer is the way to go. These resin printers, however, are a bit more expensive than your traditional filament printers. A few hundred dollars will buy you a serviceable i3 clone, and less than a thousand will get you a real Prusa capable of printing in four colors. The premier desktop resin printer, the Form 2 from Form Labs, starts at $3500 USD.

A $99 Smartphone Powered 3D Printer?

What if we could reduce the cost of a photopolymer resin-based 3D printer by taking out the most expensive components — and replacing it with something we already have? A smartphone. That’s exactly what OLO hopes to do.

A resin-based 3D printer, at least on the mechanical side of things, is quite simple. It’s just a z-axis really. Which means if you can use the processing power and the high-resolution screen of your smart phone then you’ve just eliminated 90% of the costs involved with the manufacturing of a resin-based 3D printer. There are a ton of designs out there that use DLP projectors to do just this. (And there have been open-source designs since at least 2012.)

The question is, does it work with a cellphone’s relatively weak light source?
