alt Hacker Newsany reason to use PETG instead of PLA? PLA is plant based, in theory bio-degradable, while PETG is produced from crude oil.

Less creep, slightly better at absorbing shocks without breaking, better failure behaviour (PLA can suddenly shatter leaving sharp edges, PETG tends to deform elastically first).

That is mostly true, PLA is ONLY biodegradable in a facility that can handle that. Your run of the mill recycling center in your city probably can't or won't take your PLA prints.
