We look for real reviews that mention product issues such as counterfeits, defects, and bad return policies that fake reviews try to hide from consumers.

With a stainless steel nozzle, HIPS plastic, and limonene for vapor smoothing, it is possible to 3D print food safe parts. This means that we’ve now solved the three problems with 3D printing food safe parts. You can also use a spray bottle to apply limonene to your parts it works surprisingly well, and it's easier than a vapor bath. The vapor-smoothed part may not be as smooth as glass, but it will be at least as smooth as a cutting board, which is generally considered smooth enough to be food-safe. And, HIPS plastic can not only be smoothed with acetone, but it can *also* be smoothed with a chemical called limonene, which is not toxic like acetone is. HIPS is a food safe plastic, and you can buy certified food safe HIPS filament from a company called Fillamentum. To solve this problem, you *could* simply clear-coat your parts in food-safe silicone, but I’m not a fan of this: coatings can chip off, and they are annoying to apply all over a part.īut what else can you do to eliminate layer lines? Well, you could use a vapor bath to smooth the part, but the question becomes, are there any plastics which are food safe, AND which can be vapor smoothed? The answer is, yes: high-impact polystyrene, or HIPS. The inevitable layer lines in 3D printed parts mean that there will always be small creases and voids where bacteria can hide. ![]() ![]() These do exist, but there's one final problem with food safe 3D printing that will affect the materials we can use.įor an object to be considered “food safe” it needs to be washable to remove germs, and this is a major problem for 3D printing. So, we need to find a food-safe filament whose manufacturer uses food-safe equipment. UltraFuse's ABS filament is not food-safe, even though the raw material is. I reached out to a few filament manufacturers about their ABS, and they said that, while their ABS itself is food safe, they could not guarantee that their extrusion machines are food safe. Even if a plastic *itself* is food safe, the factory equipment used to turn it into filament might *not* be food safe. Many plastics are not chemically safe to put in your mouth. The ones supplied by Prusa are nickel-plated steel, which isn’t ideal, but you can buy nickel-plated cookware, so I’m going to say that this is probably fine. These are a little harder to find in stainless steel, but some do exist. The only remaining issue then, is the extruder gear. You can also buy a stainless steel heatbreak, just to be sure. You can even buy stainless steel nozzles that are certified food-safe, like the E3D V6 stainless steel nozzle. To fix this problem, simply use a stainless steel nozzle. Your nozzle wears out over time, and that worn material (which may contain lead) goes into the molten plastic. But each of these problems can be overcome. Made of food-safe HIPS plastic with a stainless steel nozzle and heatbreak, and then vapor smoothed using limonene.įDM 3D printing doesn’t lend itself to making food safe objects for three main reasons: the printer, the plastic, and the layer lines. TL DR, to create food-safe 3D printed parts, use a stainless steel nozzle and heatbreak, print with food-safe High-Impact Polystyrene (HIPS) plastic from Fillamentum, then sand and vapor smooth your printed parts using limonene to get rid of the layer lines.Ī 3D-printed, food-safe viking drinking horn.
