natural PLA is foodsafe right?

Recommended Posts

You'd have to check with the manufacturer, it's not inherently food safe just because it's listed as "natural PLA". You don't know how it was processed/stored/etc. Also, what about the rest of your machine? Can you be sure that everything is safe in there? Personally I would never use a printed item to eat/drink out of, I value my health more than that.

I once asked Colorfabb a similar question about XT and got the answer that the material itself might be food safe but looses this safety if printed on a printer with a hotend not entirely made from metal. Which is the case for Ultimakers.

 

Same goes for U-PET.

The PLA we use does not have the food safe certification from our manufacturers. (Not even natural PLA)

This topic on the RepRap forums has quite a bit of info on food safety:

just because the crevices in it and not being able to put it in the dishwasher, i wouldn't make any cups and things to eat with for my kids. i did make a toothbrush holder for them out of 'natural' pla. it was wet a lot, rinsed, toothpaste spills, ... after about a month it had a coloured stuff in the crevices that was not toothpaste. chucked it out.

Natural PLA is food safe, yes. Additives during the filament production and your 3D printer itself is probably not. Lubricants or other additives like mould release agent (unlikely but who knows) or lubricants may be highly toxic. Don't suggest you to let your print job make direct contact with whatever you're preparing to eat.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
