“REPLACING 3D PRINTING FILAMENTS WITH LIGHT RESULTS IN TRULY ONE OF THE MOST AMAZING 3D PRINTS EVER BUILT”
When it comes to 3D printing on FDM based 3D printers, there are plenty materials and colors to choose from today. One ingenious man, named Ekaggrat Singh Kalsi, however, decided to use this process to try something entirely out of the ordinary: try 3D printing with light as a filament.
As you may know, most 3D printers use print technologies where they print ‘layer wise’, converting a CAD file directly into a solid object. The parts come off the printer as full 3-dimensional items. Ekarggrat decided to implement an entirely new concept within the print process. He wonder what would happen if instead of using traditional filament, he used LED lights, thus he set out on a mission to find out.
A Virtual Printing Reality
Of course you may understand that tangible objects couldn’t be printed in light, as we all know that light is intangible. However, utilizing a camera enables the visualization of a complete 3D printed object, built entirely out of light. He then took his camera, set it to the ‘BULB’ mode, and took a photograph using a very long exposure value. This was while the 3D printer moved using the LED light on the path he defined in the gcode. The extruder on the printer was turned off, so that it didn’t actually print with traditional filament.
Painting with Light
This is a twist to an age old technique called ‘light painting’. The results? They were quite incredible. You can see each layer that the 3D printer moved around, shining its LED light, that was attached to the print head, as it went layer-by-layer until the print was complete. Of course, there is no end product other than these fascinating photos that were taken.
The entire project took Ekaggrat only two days to complete, and he isn’t stopping here. If we understood it correctly, he plans on implementing a RGB LED to add some more color to his modern ‘light painting’ technology.
We’re curious what’s next, and will definitely update on what’s coming!
