Formon Core is a simple plug and play Desktop 3D Printer that uses FDM (Fused Deposition Modeling) technology. It has a build volume of 14cm x 12cm x 10cm, and a footprint of 30cm x 30cm x 21cm. Our challenge was to embrace the magic of 3D printing in its core function, that is building a physical model from digital input and the whole 3D printer revealing the making of the object. Our design approach was to create an easy to use 3D printer which will automatically be perceived as such. In order to achieve this simplified perception, Formon Core is designed as a closed box, which opens upwards through simple lead screws, while revealing the object that it is printing. In this design, we have removed all the mechanical and electronic parts which are unnecessary to be seen from the user. They just complicate the perception of the machine, which we see as a barrier in the current 3D printers. If we want more people to use these magical devices, they shouldn’t look as industrial machines in our desks but rather as magic devices that simply make physical objects. Users don’t need to know how they work, they just need it to simply work.
