Owl Facing Left - Negative Mold for Low Melt Metal in ABS Casting

thingiverse

This is a basic mold for casting the Owl Statue Facing Left in low melting point metals like Rose's Metal (208F), Field's Metal (144F), etc. Ensure that you use an alloy that won't exceed ABS tolerances. I recommend high-quality "natural" ABS with no dyes or colorants. You can soak off the ABS using hardware store grade Acetone. Allow the metal plenty of time to cool as it can take hours to reach room temperature. I suggest printing the mold with ~6 perimeters, 30% infill and print slowly with no cooling fan for best interlayer bonding to minimize cracking as much as possible. My first attempt, a 4 perimeter mold with 20% infill resulted in molten metal leaking into the interior infill space. Most of the 5 perimeter 30% infill molds for this and other models I've made have gone well, so 6 should be about perfect. Have fun, stay safe, and keep it sane. Hot metal can cause severe burns VERY quickly and solvents are flammable and potentially poisonous and need to be handled appropriately. Do your homework first.
