PLA vs PETG vs ABS vs ASA vs TPU: Ultimate Filament Comparison 2025

Real strength tests, temperature results, print settings, and exactly when to use each filament in 2025 – updated with the newest CF and recycled blends.

1. PLA – Still the Beginner Champion

Cheapest, easiest, and now available in matte, silk, wood, and glow versions that look incredible.

2025 reality: PLA+ and recycled PLA are now almost as strong as cheap PETG and far less stringy.

  • No enclosure needed
  • Best detail & surface finish
  • Biodegradable options
Use for: Everything that stays indoors
Strong PETG mechanical parts and drone frames

2. PETG – The Real 2025 Winner (90% of my prints)

Stronger layer bonding than ABS, food-safe, UV-resistant versions, almost zero warping.

Prusament, Polymaker, and eSun PETG are now so good that most makers have completely dropped ABS.

If you only buy one filament forever → make it PETG

3. ABS & ASA – Only for Heat & Sun

ASA = UV-resistant ABS. Both handle 100 °C+ and can be acetone-smoothed.

Only buy these if your print will sit in a hot car or direct sunlight – otherwise PETG wins.

4. TPU – Rubber That Prints

95A is the sweet spot – flexible but still printable on direct-drive machines.

Slow speeds (20–35 mm/s) but worth it for phone cases, seals, and vibration dampers.

Every maker needs at least one roll

5. Nylon & Carbon-Fiber Blends – End-Use Parts

PA6-CF, PA12-CF, and PETG-CF are now under $60/kg and insanely stiff.

Use when strength-to-weight actually matters (tools, jigs, drone frames).

The future of functional printing

2025 buying advice in one sentence:
Start with PLA → graduate to PETG forever → keep one roll each of ASA and TPU → add carbon fiber when you’re serious.
