I designed this as a logo-based coaster for Rose-Hulman.

Printing: 100% infill, no supports needed.

For the red, I used 3D Solutech "Merlot" color. Nothing special for the white although I think it is Hatchbox white.

I switch colors as soon as the logo starts printing for contrast. Once printed, I fill in with epoxy to get a smooth surface on top. I've found that printing with 100% infill reduces the odds of bubbles coming out of the print and setting in the epoxy as it is curing.
