The custom fabrication thread! (Post pics of stuff you have made)

Honestly haven't seen a reason to. The PLA burns out nice, doesn't stink, and is cheap. Done about half a dozen lost PLA investments and have yet to see any flaws that I would chalk up to the filament not burning out even on stuff with pretty thin sections - mostly just air bubbles, or learning what I need to do better on gating/runners. What I'm seeing, Moldlay might melt out at a lower temperature, but if you get PLA hot enough it just vaporizes and or burns.
My cheapass burnout kiln is an old electric oven that I crank the temperature way the hell up on. Might go faster if I disable the safety switches on the "clean" function, but after one experiment where the plaster had rather too much moisture at the time I poured the aluminum, I'm really conservative about making everything for along time beforehand.

Well, ok, to be perfectly honest, the timing actually is "start it in the morning and shut it off when I get home from work, start again in the morning the next day, text my dad to crank up the temp on my lunch break, and pour when I get home from work". The one time I wasn't conservative on time, I got a lot of steam and a lot of aluminum bubbling and spitting - it scared me enough that I don't want that happening again.
