Updated below! Here’s a sneak peek:
Made a shallow box, smoothed some sugar in the bottom with card stock, and rasterized a solid star at 1000/80 @125 lpi.
The box (around 3cm deep) kept the sugar from blowing, but also localized a bit of smoke. There was no movement from the fans, but the sugar grains pop around a bit as the laser hits them.
At these speeds, there’s not any perceptible yellowing, and the star seems fairly sturdy.
- A shallower box would hold the sugar but maybe hold less smoke.
- Fine-grained sugar would probably work better.
- Is sugar smoke any harder on the GF than the other smoke I’ve created?
My girls were fascinated. We’ll see if any edible masterpieces appear in the future…
