France is great. apparently you get money there from the government to mount tatto machines on 3d printer and draw circle tattoos on real people. cool.
In october 2013, a famous design school in Paris, ENSCI les Ateliers, hosted a workshop organised by the French Ministry of culture. The idea was to use images, videos and sound fallen in the national pubic domain and use them in a sort of “Mashup”. The event was called Public Domain Remix.
The students had one day (8 hours) to pick their digital material and transform it, hack it or remix it.
Le FabShop, was invited as a digital manufacturing expert to help the students realise their project.
After a short brainstorm, all the teams came up with similar ideas, except one, who really went out of the box with their concept. They had this silly idea of making a machine that could automatically create tattoos taken from a bank of images. They learned from le FabShop's representative that their concept was more than feasible. It could be prototyped by themselve, using the school's equipment.
In one afternoon, they managed to hack a Desktop 3D printer and enable it to trace on skin, using a pen instead of the extruder. The crowd was amazed and the Minister of culture even came to see the projects, but the young designers didn’t want to stop there. They wanted the machine to make REAL tattoos, on REAL skin, so they kept working on the project during their spare time, with some help from teachers and other students.
They borrowed a manual tattoo-machine from an amateur tattoo artist and found some artificial skin for the first tests. They chose to draw a simple circle. The perfect shape to test the precision of the process. It worked! But now they had to find a volunteer to be their “guiney pig”…
Somehow, they had no difficulty. A lot of people where excited by the idea of being the first human tatooed by a “robot”.
The big difficulty was to repeat the same exercise on a curve surface and on a material that has much more flexibility than silicone. Many tricks were tried to tighten the area around the skin ( a metal ring, elastics, scotch tape...) but the most effective one was a scooter’s inner tube, open on the area to be marked.
