Color changing biohazard coaster

This is a coaster that features a color-changing inlay. When a hot beverage is set down on the coaster, a biohazard symbol emerges. The color changing filament is M3D's Chameleon 3D Ink. Because it is subjected to heat, I made the coaster base from ABS.

Pretty straightforward assembly, just print the two parts in the desired color(s) and glue together. I also sealed the coaster with XTC-3D epoxy.

Post-Printing

After printing, I lightly sanded the body and logo. I glued the two pieces together and then sealed the entire coaster with XTC-3D epoxy.
