Micro 3D filament food safe

Question

Before you put duplicate from this Which are the food-safe materials and how do I recognize them? please read

I need to know if this 3D Ink™ (PLA Filament) is food safe

Answer 1

In general, PLA is known as a "food safe" filament, especially Natural PLA. However, filament suppliers have different processes that may detriment the food safe quality.

Doing a little digging, I found an article on the M3D site which mentions the following about their filament

All of our products, including our filaments are made from 100% non-toxic components and considered generally safe under normal use. They are not considered a chemical, or a hazardous material by OSHA standards. Therefore, OSHA defines it as an "article" and does not require MSDS sheets. You can see more information about that here: http://www.ilpi.com/msds/faq/partb.html#article

So, without contacting M3D directly to acquire an MSDS (or asking if its food safe), you will not find one online.

Here is an article on a few tips for printing food safe objects as well. In a nut shell, don't 3D print food handling objects with crevasses, using uranium, or intend to put in the oven (a.k.a common sense).

Answer 2

In general no filament is safe as the printing process leaves "nooks and cranies" between the layers where germs can gain a foothold.

For food safe, I would advise:

• print with white filament
• use an acetone vapor bath to smooth and melt many of the "nooks and cranies" away.
• Use a spray polyurathane and coat with 3-4 layers to reduce the evil "nooks and cranies" even more.

At that point it it should be dishwasher safe and food safe.
