Spike is an hacked delta 3D printer used to punch a paper sheet.
The experiment started as a test for printing graphics and texts for Laura, a young high-school student whit limited vision, who wants to study engineering but find difficult to read graphics and images compared to the easiness of braille written
By coding the g-code with Rhino and Grasshopper it's possible to build a path that simplifies an image or a graphic (for instance Young modulus diagram) then interpolate the curve with points, varying in distance and pressure, in order to allow multiple path to cross and still being
Spike can paint too. It is possible to position a tank filled with liquid, or resin, where Spike can dip at a certain frequency, realizing an image visible to everyone.
