Food-safe filament makes 3D printing for the kitchen sound more settled than it really is. The label feels reassuring, especially when printers already do such a good job with brackets, clips, drawer organizers, and replacement bits. It is easy to look at a cleaner material spec and imagine cups, utensils, snack trays, and custom containers finally becoming fair game. The problem is that the filament is only one piece of a much messier food-safety puzzle.
