What would one need to do to make 3D printed PLA cookware safe to use?
It's possible to 3D print cookie cutters or measuring cups or dumpling makers with PLA, however its not certain that doing so would be safe.
The two problems people mention are,
- Possible impurities or chemicals in the PLA
- The microscopic pores in the object created by the 3D printing process which gives bacteria a place to hide.
Is there a way of solving those problems?
