[JBV Creative] recently became a proud owner of a laser cutter and, like most of us, started to think about what they could make with it. The answer was simple, a clever little piece of art or puzzle made of stacked acrylic.
He created some text and extruded it from a single point, but not every part intersected with every plate, giving each plate an indecipherable appearance. This allows a small light source (like the LED likely on the back of your phone) to cast a shadow on the wall. With some 3D printed brackets and spacers, it was mounted to a nice piece of cherry plywood. Overall, the technique is quite simple and easy to understand. [JBV Creative] didn’t include more detail on the process, which is a shame because it looks like a beautiful effect to recreate for some puzzles.
These glowing coasters are fantastic if you’re looking for engraved acrylic with a light source. Or this puzzle that lights up as the pieces are placed.
The concept is perfectly clear to me, I like concise messages
This would be great in an escape room!
Using tomography, you could stack the layers more densely for direct viewing, use dithering for greyscale, and create a monochromatic light0field image: http://www.cs.ubc.ca/labs/imager/tr/2011/Wetzstein_SIG2011_Layered3D/TomographicLightFieldSynthesis.pdf
He should write something like: “Stop procrastinating and go back to work!” :-D
Or a present from the parents to the university student: “What do you think which money you trowing out the window, Head back into Books or Papers!”
