Created by Bjørn Karmann in collaboration with Nicolas Armand and Lars Kaltenbach, PyroGraph is a CIID project inspired by the thermal printers used for receipts in all shops. The PyroGraph analyses an image and converts it into dots that aare then burned with a 450 °C tip on to paper. The time of contact between the iron and the paper determines the grayscale of the dot; the longer it presses against the paper, the darker the dots get.
The machine uses a paper roll (so the length of the printed piece can then be up to 100m) and a head moving on a fixed x axis, controlled by servo motors and a custom Processing app developed by the team. In addition, The PyroGraph will also listen to the ambient sound in the room, to create a connection between the space and the printer. The drawings will be distorted depending on the sound activity of the room in which it will be displayed.
