Is PETG stronger than PLA?

PETG usually takes a harder hit before it cracks, because it bends a little first. PLA is stiffer, which is why it holds sharp detail so well. Neither one is stronger in every way.

Can I mix PLA and PETG in one order?

Yes. You pick the material for each part when you order, so one order can use PLA for some pieces and PETG for others.

Which one should I pick if I am not sure?

Pick PLA for anything that stays indoors and does not get knocked around. Pick PETG for anything outside, in a car, or in a busy workshop.

Does PLA smell or feel different from PETG when it prints?

PLA has a mild, slightly sweet smell while printing, since it comes from plant starch. PETG has less smell but can string a little more between parts. Neither difference affects the finished part you receive.

PLA vs PETG: which one for your part?

Quick answer

PLA is our everyday material. It prints crisp, holds fine detail, and comes in the most colors. Pick PETG when a part will take heat, hard knocks, or life outside. PETG bends a little before it breaks and handles heat better than PLA. Both print well. If you are not sure, pick PLA for anything that stays indoors and is not under stress, and PETG for everything else.

We print in two materials, PLA and PETG. Both are good plastics. The right one for you depends on where the part will live and what it has to put up with.

What PLA is good at

PLA is a sturdy plastic made mostly from plant starch, like corn. It prints crisp and clean, holds fine detail well, and comes in the widest range of colors we offer. It is a great pick for toys, decor, organizers, desk items, and gifts. Most things in our shop are PLA.

What PETG is good at

PETG is the same family of plastic as a water bottle. It bends a little before it breaks instead of cracking outright, and it handles heat better than PLA. It is a strong pick for workshop parts, car accessories, garden gear, and anything that gets knocked around or lives outside.

	PLA	PETG
Made from	Mostly plant starch, like corn	The same plastic family as a water bottle
Best for	Toys, decor, organizers, desk items, gifts	Workshop parts, car accessories, garden gear, anything stressed or outside
Heat	Published PLA data sheets put softening around 130 to 149 degrees F (55 to 65 degrees C)	Holds its shape at higher heat than PLA, per published PETG data sheets
Impact	Can crack under a hard hit	Bends a little before it breaks
Colors available	The widest color range we offer	A smaller color range than PLA

PLA and PETG, side by side.

Picking by what you are making

Ask two questions. Will it sit in a hot car or in direct sun for hours? Will it get bumped, dropped, or bent? A yes to either one points at PETG. Otherwise, PLA does the job, prints cleaner detail, and gives you more color choices.

Read our guide on 3D printed parts in a hot car and our guide on outdoor use for more on those two cases specifically.

Worth knowing

The honest limits

Neither material is rated for food contact by us. Neither is fireproof. Color choice is smaller for PETG than PLA today, so check your color options before you decide. If your part will sit in daily hot sun or a locked hot car, read our guide on hot cars before you choose.
