Intro
PLA and ABS are two of the most common filaments. Each has strengths and trade-offs. Choosing the right one depends on the part’s job, your workspace, and your tolerance for tuning.
PLA at a glance
- Easy to print, low odor
- Low warping, excellent surface finish
- ~200 °C nozzle / 60 °C bed
- Brittle and not heat-resistant
ABS at a glance
- Stronger and more heat-resistant
- ~240 °C nozzle / 100 °C bed
- Warps more; enclosure recommended
- Noticeable fumes; ventilate
Direct comparison
- Ease: PLA ★★★★★ / ABS ★★☆☆☆
- Strength: PLA ★★☆☆☆ / ABS ★★★★☆
- Heat: PLA ~60 °C / ABS 100 °C+
- Finish: PLA excellent / ABS good (benefits from acetone vapor smoothing)
Printer requirements
- PLA: open-frame OK
- ABS: enclosure, hot bed, and good ventilation
FAQ
Which lasts longer outdoors? ABS/ASA resist heat and UV better; PLA becomes brittle in sun/heat.
Can I print ABS on a PLA-only printer? Not reliably. Expect warping without an enclosure and higher bed temps.
Wrap-up
Use PLA for easy, clean prints. Use ABS when you need strength and heat resistance—and have the setup to handle it.
