PLA is also usable, its made from corn i think
its just a lower grade material as it ages and looses properties, more so than PETG
you could probably use ABS as well, some kitchen items are made from it so as long as you keep it cold you might be able to use most materials
Nah. Not if you want to sell it. Even PETG is sketchy then. But this is my opinion. I think that the whole manufacturing process with fff 3d-printing not suited for products with food contact. Especially the layerintersections are great for bacteria.
I have already printed cookie cutter with PLA, but for one time usage at home.
And yes it is often corn in 3d printing filament, but PLA just means that it is a polymere made of polylactic acids. D
