We’ve all twirled sparklers around in the darkness to write fleeting circles and figure eights with the light they give. Some of us have done it with the glowing end of a cigarette, too. Hackaday Projects user [ekaggrat] went a step further, painting with an LED mounted on the print head of his newly built 3DR Delta and capturing the LED’s path with a DSLR camera set for long exposure.
He started by creating a mesh model. From there, he converted it slices and G-code in Grasshopper. The LED is connected to pin D11/servo pin 1 on the RAMPS board. [ekaggrat] used the M42 G-code extension toggle the pin and write the slice lines with light. He has future plans to use an RGB LED, and we hope he shares that on the Projects site as well.
While this isn’t the most advanced light painting setup we’ve seen, it’s still pretty awesome and far more accessible. There is more information on his site, and you can grab the G-code from his repo. Stick around to see a video of the process.
So this takes an image created on a flat computer monitor and creates…a flat digital image.
Save some time and take a screencap?
i will keep that in mind next time !!!!!
He should make this into a 3D printer, it sure looks like it could do it.
It already is a 3d printer

How about shoot with multiple cameras for some bullet Time “hologram” effects?
had thought of that … but sadly i just have one dslr for the moments and no phone i am aware of has that kind of long exposure
You can still do animation. It will be long-exposure stop-motion animation. If you connected your dslr trigger to computer, everything could be done automatically.
This is super cool; thanks! I can’t wait to try it! I totally missed that it was on a (delta) 3D printer until I actually read the article.
I was really hoping for so much more…
Help me Obi Wan Kenobi, you’re my only hope.
