Brass sometimes has lead added because it makes it easier to cut/machine, but its not universal for all brass. I agree with you that the amount of lead passed through the nozzle is probably negligible. You could probably even eat the nozzle and not suffer and lead based side effects. They make stainless steel nozzles specifically for "food safe" applications, but I guess for someone doing it for themselves, there is a difference between "food safe" and "safe for food".

no lead in brass

I'm pretty sure c360 brass rods contain roughly 3% lead, and I'm pretty sure most if not all brass 3d printer nozzles are made from c360 brass. I doubt that you would actually get enough lead in your item to make it a realistic danger, but I don't think you could call it "food safe".

MonoJect syringes are one but dont know anyone that does reuse them anymore and most order them with sharps safe needles made into them now as theirs is easy to use no way to stick yourself covering needle. I know this due to being purchasing for the clinics I worked for also.

But understand all the risks people are mentioning are very, very real, and could potentially be very harmful to you or the person you give it to.

So here's my two cents:
One thing I don't hear people mention a lot is uses. If you want to print a 'food safe' item then I would expect it to be used only once and immediately thrown away. This works very well for cookie cutters, in fact I collaborate with a local bakery making one time use cookie cutters for special orders.

However, it really depends on what you plan on printing. If you're printing a cookie cutter which won't contact the food for very long then it's not a big deal, if you're printing a cup which will hot coffee it's a different story.  We published a blog on 3D printing and food safety where we go over top concerns and tips to reduce these risks.

At least a soak in boiling water would help. Of course, then you have to worry about the moisture and heat destroying your print.

Well this is is food grade what you can print containers and that out of?


Its not about the chemical.  PLA is the same stuff they package produce in at the supermarket. The issue is the tiny holes between layers that food particles and liquids can get into. Once in there they cannot be cleaned out. They will lead to mold and bacterial growth that will contaminate any new food or beverage placed in the container.

Even vapor finishing which does not work on any of the food safe stuff still leaves small pores and voids that can support growth. All it takes it one of the right germ and you could be hospitalized or worse.

Its a cool idea that many have done not knowing the risk, but for me personally not worth my life.

There is guy on ebay that sells printed cookie cutters. Again bad idea since cookie dough contains raw egg and potential e.coli.
