In this Instructable, I will explain how to use the rotary attachment for the Trotec Speedy 300 to make extremely detailed etchings around beads. The pictured beads include globes, beads with numbers and words spiraled around them in continuous lines, and some with a basic silhouette monkey to man evolution picture. I have lots more ideas for images that would look cool etched onto beads (Death Star Beads!). I'm sure you've got some ideas too - put them in the comments!
I made it at TechShop.
Step 1: Materials
- spherical, cylindrical, barrel shaped, or other approximately round beads. I bought mine here.
- spray paint, wood stain, anything you think will change the color of your beads in an interesting way so long as it's laser etch-able. I bought Flat, Satin, and Gloss spray paint, and all three worked well.
- laser cutter/etcher with a rotary attachment
- bead jig (see next step)
