It seems doubtful; looking at the FAQs on the Matterhacker site https://www.matterhackers.com/store/...GICAgObZqrYKDA they talk about it melting and running out of the mold, but not about it burning out cleanly. It seems that they had other sorts of molds in mind when they developed this material.

I have heard about people having success in burning out regular PLA, though. I'd use Plasticast investment, which resists the expansion of plastics when heated, and goes to a higher temperature, burn it out hotter and longer than an equivalent wax part, and introduce a little air to the kiln at the end of burnout to help combust any residues.
