Review on 🔴 Red 1 by Richard Surveh

Does what it says on the tin. It's not exactly blue, more of a light blue, slightly purple (#A4A5FD) when cold and pale pink (not hot pink) when heated. It's blue at room temperature and pink at body temperature, meaning the prints will change color when you hold them in your hands. The finish is like silk and the prints are slightly darker, shinier and smoother at 190°C than at 220°C, but if you need strong layer adhesion for functional details it's usually better to use a hotter print. Printing temperature doesn't seem to affect the ability to change colors. Printing Tip: After the print has cooled sufficiently to be removed from the build plate, place the print in the refrigerator to speed up color recovery from the "cold" state. Use: Color-changing children's toys?
