Plastic for my 3d printer, and how long it lasts.

The 3d printer kit I ordered can print several types of plastic. The 2 that are currently frequently used are ABS and PLA. PLA is a biodegradable plastic made from corn starch (http://www.cupdepot.com/PLA-FAQ.htm). ABS is a plastic that is food safe and ok to use in aquariums and such. PLA is also food safe but being biodegradable I am unsure about its suitability in an aquarium.

Being that I have the laBOREtory I think it’s only suiting that I do an experiment. I’m going to test ABS and PLA with the liquids in the list below. I am unsure if I want to do this by printing small cups or by placing pieces of filaments in glass jars. Either way I’m going to test each of the following for compatibility with plastic and see how long it takes to dissolve.

  • coke
  • Mountain Dew
  • hot water
  • aceetone
  • isopropyl
  • salt water
  • sugar water
  • baking soda
  • bleach
  • lye
  • wd-40
  • milk
  • drain cleaner
  • gasoline
  • testors glue
  • lemon juice
  • Hydrogen Peroxide

 

I could just look up the solve the solvent had ability but that would be too easy. http://capolight.wordpress.com/2010/08/10/solvent-compatibility-and-plastics/

What am I missing?.
