Flammable warning coaster - dual extrusion

thingiverse

Dual Extrusion Flammable Warning Coaster Experiment I successfully conducted an experiment using PLA filament in two colors: black and glowing yellow. Print settings included a 2mm layer height, 100% infill, and a print speed of 40mm/s. I also utilized a priming pillar for both nozzles to ensure proper extrusion. To avoid color contamination on the first layer, I was extremely cautious during this stage. Once past the initial layer, the outer ring of the coaster served as an effective ooze shield, preventing any unwanted material from oozing out and creating a mess.
