petg or pla

[Bikeracer2020]

I recommend pla for beginners because it is easier to operate. This is a comparative article about petg vs pla.

From that article about PLA being biodegradable.....

PLA: PLA is a biodegradable material that can degrade rapidly and eventually decompose into natural substances. It is more environmentally friendly and suitable for disposable and short-term applications.



"It is important to understand PLA is not a biodegradable material in just any environment, it is a compostable material only in industrial environments and shows very little mineralization(not biodegradation) in the majority of environments."

1) PLA is not biodegradable. It is degradable.
2) Enzymes which hydrolyze PLA are not available in the environment except on very rare occasions.
3) Proteinase K catalyze the hydrolytic degradation of PLA
