Ecstasy by Eric Gill - Mold for Low Melt Metal in ABS Casting

This is a basic mold for casting Eric Gill's statue Ecstasy in low melting point metals like Rose's Metal (208F), Field's Metal (144F), etc. Make sure to use a metal that won't exceed ABS tolerances. I recommend high quality natural ABS with no dyes/colorants. You can soak off the ABS using hardware store grade Acetone. Give the metal plenty of time to cool as it can take hours to reach room temperature. I recommend printing the mold with lots of perimeters, 30% infill and print slowly with no cooling fan for best interlayer bonding to minimize cracking as much as possible. You may wish to try printing this vertically for best preservation of details. If so, make sure you know how to get good bridging results out of your printer. May wish to print vertically and upside down so that any poor bridging is hidden in the base of the statue. Have fun and keep it safe and 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. UPDATE (3/29/2016) - Printing this mold vertically, with the heads closest to the build plate, does work and looks like it produces a more detailed mold. This can be done without support, but you will either want to manually administer the print when it gets near the top or alter the G code to alter your speed, temperature and even fan settings to get it to bridge the top in this orientation. Print the rest slow, hot and without fan and then alter the settings to get the bridge established and then back it off once you have a layer to build upon. My bridge was quite messy (required some cleanup afterwards with xacto) and spanning that initial 5 cm gap would have been impossible had I not altered the settings.
