Toxic warning coaster - dual extrusion

thingiverse

Toxic warning coaster designed for dual extrusion prints, featuring a striking combination of PLA-black and glowing yellow materials. Conducting experiments with this setup, I employed 2mm layer height, 100% infill, and a print speed of 40mm/s to achieve optimal results. Both nozzles were primed using a central pillar to ensure thorough coverage. Key considerations for successful printing include exercising caution on the initial layer to prevent color contamination from one material bleeding into the other. However, once established, the outer ring serves as an effective ooze shield, minimizing the risk of extrusion interference during subsequent layers.
