I am trying to create a ceramic shell to cast a two-foot-tall bronze sculpture. I tried using the castable wax, but the ceramic shell cracked apart during the burnout. The sculpture foundry did not do the FL recommended heat schedule, and will not do that long of a process for me. I assume the castable wax 40 will have a similar expansion problem, but let me know if anyone has had luck at scale. The foundry recommended PLA. Does FL offer a resin that can burn out like PLA?
Otherwise, I am open to suggestions for combining FL printing with bronze casting.
Here is a picture of the design and the cracked ceramic shell:
The one I used was the castable wax 20%, but I am not committed to that material. If you would be willing to test the castable wax 40 that would be greatly appreciated. I would really like to have some more information on this before moving forward. Please let me know if you decide to run a test and any of your results.
