My recent Linkedin post on PETG vs. PLA sparked such a discussion I thought it worthwhile to include on my website’s blog. To view the comments & wealth of knowledge in the discussion, view the entire post on Linkedin.
Why does everyone seem to use PLA when there’s…
So many better options, honestly. 🤷♂️
There are countless types of filament to choose from, depending on desired strength, flexibility, and durability.
The hobbyist world of FDM printing has defaulted to PLA, but I’m here to give you a few reasons why you should be using PETG as your default material and leave PLA in the dust.
1. PLA is brittle.
When it fails, it fails fast & catastrophically.
PETG is tougher.
Even though the strength is slightly lower, you trade that strength for compliance and impact resistance.
2. PLA is low-temperature.
It warps when left in the sun, or even in the car on a hot day. Ask me how I know!
PETG withstands higher temperatures.
It’ll stay strong in many temperature applications that PLA does not.
My go-to filament in FDM is PETG. I’m slowly replacing my stash of PLA with PETG because of the reasons I’ve listed above.
What’s your take? Agree or disagree with me?
