The 30-second answer
Buy PLA+ if you only buy one roll — it prints almost as easily as PLA and survives drops, desk heat and warm cars that shatter plain PLA. Buy plain PLA when price matters most or for decorative models that live indoors. Buy PETG for functional parts that work outdoors, in cars, or under real load. Whatever you pick, verify every roll genuine — counterfeits don't care which plastic you chose.
Head to head
- Price: plain PLA is cheapest, PLA+ costs a little more, PETG sits in the middle
- Ease of printing: PLA wins, PLA+ is a close second with no enclosure, PETG needs tuned temperatures and dry storage
- Toughness: PLA snaps, PLA+ bends much further before breaking, PETG has the strongest layer bonds
- Heat resistance: PLA softens near 60°C, PLA+ holds a little longer, PETG holds shape to about 80°C
- Outdoors: PLA degrades in sun and rain over months, PLA+ resists better, PETG shrugs off weather
- Surface finish: PLA prints the crispest detail; PETG may string unless dried and tuned
Which one for your project?
- Miniatures, display models, prototypes: plain PLA
- Gifts, toys, brackets and anything that gets handled: PLA+
- Outdoor parts, car interiors, load-bearing prints: PETG
- Your very first roll: start with PLA+ — see the beginner's guide
Dial it in after you choose
Settings differ more than the spools suggest. Plain PLA prints around 200–215°C nozzle and 50–60°C bed. TerraEco PLA+ follows its label: 200–230°C nozzle, 45–65°C bed, no enclosure — start at 215°C. It is a toughened blend, not identical plastic. PETG wants 230–250°C nozzle and 70–85°C bed.
