You should probably review the MSDS for the specific filament you're working with. The first one I looked up [1] contains 1,4-Dioxane [2]. In my experience any time you heat up plastic you're risking exposure to dangerous VOCs. It doesn't matter if most of the molecules were derived from corn.
There are plenty of things labeled "non-toxic" which, when heated, produce toxic fumes. Pretty much every children's toy in existence is toxic to breathe when melted.

- VLM 8y agoIt would seem there's an obvious startup opportunity for filaments that are sold based on cleanliness of product rather than the current marketplace of pigment and cost. It would seem trivial to distill out the dioxane to an unreasonably low impurity level. As with pharma, people may not like the cost of synthetic pure bespoke molecules, but some will sell.
