Aron Bothman, fresh graduate from the California Institute of the Arts has built a 3D printer to print a 3D light painting and light animation, for his film The Red Witch.
His creation was inspired by a Beijing-based artist Ekaggrat Singh Kalsi, who has previously attempted modified a 3D Printer to print light.
“I’m an animator and artist based in Los Angeles. I graduated from the animation program at CalArts a couple months ago, and am currently working as an artist at JibJab, a small studio in LA. I originally learned about 3D printing in middle school from my dad, who teaches mechanical engineering at UCSB, and who helped a lot with thinking through this project. As a stop-motion filmmaker, 3D printing allows me to tackle more ambitious projects on a short production schedule than I might be able to otherwise,” said Bothman.
The 3D printer used to create the light animation was developed by Bothman himself and his father, who purchased a small delta model kit and transformed it during the assembly of the parts. Upon its completion, Bothman placed an LED in the conventional “hot end” section of the 3D printer, to capture light and transform it to a format compatible with videos and films.
The process of creating the light animation is straight forward. Each “Maya” image was captured to the printer one frame at a time, like a stop motion. By continuously building light on top of each other, it ultimately creates an illusion of movement.
As seen above, each print of light is carefully laid on top of another, creating delicate layers of light which transforms into an animation for films.
