Color changing biohazard coaster

thingiverse

This is a coaster that boasts an eye-catching color-changing inlay. As soon as a steaming hot beverage is set down on it, a biohazard symbol suddenly appears. The remarkable color-changing filament used here is M3D's Chameleon 3D Ink. To withstand the heat of hot beverages, I cleverly designed the coaster base from ABS. The assembly process was surprisingly simple - just print the two parts in your preferred colors and attach them together with a strong adhesive. I also added an extra layer of protection by sealing the coaster with XTC-3D epoxy. Print Settings: Printer Brand: RepRap Printer: Makerfarm 12 Rafts: No Supports: No Resolution: Printed at .2mm height with a .4mm nozzle Infill: 25%, 1mm thick top and bottom layers Notes: Feel free to print this coaster as you see fit. However, I strongly recommend using ABS for the body since it will be exposed to hot beverages. Post-Printing: After printing, I carefully sanded the body and logo to achieve a smooth finish. Next, I attached the two pieces together and sealed the entire coaster with XTC-3D epoxy to give it an extra layer of protection.
