I'm about to try lost PLA casting for the first time and am wondering about what burnout / firing cycle I should use, given that I'm using Suspendaslurry as my investment material. I was surprised to find that RR doesn't seem to have a suggested cycle published, nor could I find an example of one used for this investment. I'll be using a Paragon SC3 electric kiln, should I remove the melted PLA afterwards or just let it stay in the chamber during the firing stage?
