Recently, Google+ in the 3D printing community raised the question of how it is possible to produce food-compatible 3D prints, as some FDA-certified 3D printing material is now available.

I thought about it and came to the conclusion that the first thing I would do was to use a direct extruder with a full metal hot end.
I would also equip the interior of the printer with UV LEDs to disinfect the print. Furthermore I would place a row of UV-LEDs directly under the extruder, next to the coolers.


So I could imagine, one would come to the goal to print food-safe the next. Of course you would have to wash the component again after printing and after all post-processing steps have been carried out to eliminate any particles and probably treat it again with UV.

However, this should not be a problem for PLA, but with other materials it looks somewhat different and would have to be reconsidered.
