light painting in color using a rgb led attached to a 3dr printer
Kalsi is an artist who has demonstrated a new system which combines long-exposure light painting and a 3D printer to produce three-dimensional colour objects sculpted out of LED lights.
The system essentially “prints” an object line-by-line, as with a regular 3D printer, but simply shines a bright light at regular stages of the process. The result is what appears to be a solid hologram — at least on video, where all the points of light are recorded and combined. The system has been in the works for more than a year, but Kalsi’s latest video is the first to demonstrate colour portraits. Other similar projects have been carried out with industrial robots or large-scale equipment, but Kalsi says his version relies on a simple home 3D printer (and some clever software).
