Like title says, is there a filament that is healthy to burn? I'm looking to buy a 3D printer to help creating support structures for my ceramics that can later be burnt in the kiln "healthily". (Performing the kiln fire at school so it has to be safe).
Does anyone know if theres any natural based filaments out there? PLA (cornstarch based) seem to have toxins and a strong ill smell according to my research.
