dad911, I have never heard of the ASA filament. I just Googled it and the temperature requirements are above my entry-level printer. My Creality printer is only suitable for PLA, TPU, PETG, ABS, and Wood filaments.

Pazuzu, Originally when I looked to see if PLA is food-safe, most sources indicated the material PLA (polylactic acid) itself fulfills that requirement as some food packaging is actually made from PLA... however, as I see now, PLA filament may not always make the grade and numerous studies show NOT to use PLA filament in food-type applications for many reasons. Plus, even if a food-safe PLA material was used on a properly prepared 3D printer, there will still be all those hiding places between each layer for nasty organisms to hide.

Since I am looking just for proof of concept, PLA filament may suffice for this initial round of testing - I will just not process any of the maple sap that has been in contact with this material. Thanks for all the help!
