Chemical Resistance: PLA is a very stable material, and so it is quite resistant to chemicals such as acetones or alcohols. Very powerful solvents such as dichloromethane are required to dissolve PLA, so everyday chemicals will not make a dent in PLA.
Does PLA dissolve in dichloromethane?
After 60 minutes without stirring at room temperature (around 20°C), PLA almost completely dissolved in dichloromethane and chloroform but showed no visible changes in other solvents (ethanol, acetone, hexane and tetrahydrofuran).
What material is resistant to acetone?
According to Palstics International’s Chemical Resistance Chart, the A-rated plastics (no solvent attack) towards acetone are: ECTFE (Halar): transparent films available. Fluorosint PTFE: white. HDPE: transparent films available.
Is PETG acetone resistant?
Materials are usually only resistant to certain types of chemical. For example, Nylon isn’t adversely affected by acetone, but can be damaged by water. Conversely, PETG isn’t affected by water, but acetone will degrade it.
Can I drink out of a 3D printed cup?
It is safe to drink from 3D printed cups as long as they’re made with food-safe filaments. Finishing the cup food-grade material will help protect it from bacteria that may invade the surface.
Can you 3D print water bottles?
California-based industrial designer Reiten Cheng has developed a unique device that’s capable of turning discarded plastic water bottles into functional 3D printing filament.
