Are there any food grade ABS or PLA? By food grade, I mean safe to use as a food container or stencils.

We have a couple of glass food containers of which the rubber cap is torn on its side. It will be a great opportunity for me to prove my wife I can make sometime useful with my 3D printer (finally).

So, on top of being food grade, it will be ideal if the material is flexible and transparent/translucent at the same time. Well, transparency is not really critical since it's a glass container so we can still see the contents.

Does anyone know any reputable supplier for this type of material?

Thank you!

It doesn't matter if the material is food grade. If the extruder nozzle is made of brass, it contains lead. And, if it contains lead, anything you print will not be food grade, even if the material is.

That's good to know. I mean, it's not good that the brass nozzle will conteminate the print out, but it's good to be aware of it.

Btw, isn' t brass alloy of copper and zinc? There are even musical instruments which are made of brass (or at least they are called "brass") and those are the type of instrument into which the player blows air with her/his mouth... I haven't heard of anyone who got lead poisoning from playing the saxophone or trumpet.

Or, does it mean the "brass" nozzle commonly used in hot ends is not really brass, but something else and we just call it brass because it's close enough or look alike?

Anyway, the other day I was reading a (very long) discussion thread about nophead's stainless hot end. It seemed like being food safe was one of the key features of this all stainless construction hot end. At that time I didn't see what the big deal was, but if brass nozzle contains lead, I can see why.

Some alloys contain lead, some don't. but brass hex rod (what nozzles are made of) is primarily made from the kind that contains lead. You need to run a cost-benefit analysis to determine if a stainless steal hot end is right for you. I'f your just going to make one thing, forget about it. You're going to spend a lot of money for a widget that's probably already available for a couple bucks.

The other problem is that printed plastic parts contain imperfections that bacteria can grow in. I couldn't find the link, but the imperfections are still there even after an acetone bath (visible through microscope). You could coat the printed part, although it's not something I would try.
