This smells yet again like a quick funding. On 03/30/16 the Trinus 3D printer launches it’s campaign at kickstarter. Fast fingers can save perhaps a quite interesting appearing 3D printer for $ 199 plus shipping.

Despite this extremely low price (the planned regular $ 299 sound even low) the Trinus 2-in-1 3D printer points out to be a solid and complete metal construction. The printer is made of 11 parts, and even inexperienced prospective should be able to build it up in 30 minutes. And because 3D printing is not enough, it will probably also able to carry a laser engraving head.

While 3D printers have become a whole lot more favorable in recent years, as cheap as the OLO is none. $ 99 for a 3D printer? How does it work?

The basic principle of the OLO is very simple and is based ultimately that OLO will have developed the first Resin that can harden by sunlight. Photosensitive Resin are dehydrated natural resins that until now only could be solidified by a laser. The resin used by OLO should be allowed to be hardened by the light of a smartphone.

If the rest of the technical construction works is quite simple. It only needs a box with glass floor, in which the liquid resin is filled. Then you need a controllable motor plate on which the object to be printed is drawn upwards. Of course, the servomotor which regulates the distance from Resin must be correspondingly accurately. The whole computation is controlled by the smartphone, that also provides the necessary light to harden the resin
