Hello form forum. I am a custom jewelry shop in Colorado and recently purchased a form3. I have been very happy with the way the models turn out, but casting the V2 wax has been dubious at best. I am currently using Kerr satincast with the manufacturer’s burnout schedule and have yet to really have a stellar cast.
I have read in various 3d printing forums that adding airflow to the bottom of the kiln can help solve the problem, but I am hesitant to start drilling the bottom of a kiln (my only kiln) that has been in service for 15+ years. I am setting up to cast tonight and thought that I would try to add a wire kiln shelf to improve air flow below the flask.
Can anyone confirm that drilling holes in the bottom of the kiln, and possibly adding a fish tank pump actually solves the problem? Does anyone shop vac the cavity of the hot flask before casting? Does anyone have any tricks that are helping? Please advise.
