Food safe 3D printing is not trivial. However, the other ones look handy enough, and we know a lot of people feel that PLA is safe enough for things that don’t make a lot of contact with food.
18. Almost all 3D printers have issues that could cause health problems. FDM/FFF printers heat plastic to a temperature that may cause it to off-gas, and these byproducts may not be healthy. SLA printers often use epoxies that may off-gas, or may be somewhat toxic prior to being cured.
An example of this case can be witnessed in the US Food and Drug Administration (FDA), where it experiences delay in the validity and adoption of 3D food printers globally as a result more emphasis must be pushed towards the clarification of policies which include personnel training, food shelf life, food safety, and facilities [41].
Food safe 3D printing is difficult to come by. GermanRepRap has released a new food safe filament, but some 3DP users aren’t sure that the process of FFF 3D printing is really all that food safe. Many conventional 3D printing filaments are made of chemicals that react to hot food’s hot temperatures. Making a 3D mug, for instance, would mean using it for steaming hot tea or coffee. While it is true that many manufactures tend to list their filaments as being inherently food-safe, you should still refrain from treating it as the
3D printing now enables users to easily produce even practical kitchen utensils at home. The biggest risk with 3D printed cups or plates, however, is to ensure food safety, as even the smoothest prints have small cracks and gaps in which germs can accumulate and bacteria can thrive. If you want to create 3D-objects, which should come in contact

To be on the safe side, it’s a good idea to avoid long direct bodily contact with ABS plastic. If you’re 3D printing a watch chain or necklace, consider sealing it with clear epoxy before wearing it. Is ABS Plastic Food Safe? ABS plastic is generally not considered food-safe, as the material is known to contain Bisphenol A (BPA).

Plastics becomes soft at lower temperatures of melting, so in this lapse the plastics release the odor that can be mixed with your food contaminating every thing. The kind of plastics for molding is silicon with food grade (clean of toxines). There's obviously some 'safe' range of temperatures for 3d filaments.
Can fit probably 4 rolls in it and its got 5C temp increments from 35-70c which come in handy handy as well as auto off timer. There was a dude on the Prusa site forums who put a spool holder in his, drilled holes into the front panel and made it a proper drybox, which was pretty neat. Definitely best dehydrator for 3d printing.
Consequently, 3D printed items are indeed safe for the storage of dry foods and generally safe for short-term contact with food, as long as they are properly cleaned (see below). It’s crucial to mention that the cleaning process should be thorough. For best results, “wash, rinse, sanitize in bleach water” should be the mantra. Pour from high up (like in image 6 in this sequence) and NOT directly on top of the object. Rather, let the material rise up and over the object. Take your time and keep your arm steady. As you pour you'll notice that as the material falls on top of itself, it resembles a ribbon (hence the name "ribbon technique"). .
