There is no single best 3D printer filament, because the best pick depends on the job. PLA is the easiest. PETG is the tough all-rounder. ABS handles the most heat. PLA+ is the tougher PLA.
How the materials compare
The table compares the four most common filaments. PLA leads ease. ABS leads heat.
| Property | PLA | PETG | ABS | PLA+ |
|---|---|---|---|---|
| Ease of print | Easy | Medium | Hard | Easy |
| Toughness | Low | High | High | Medium |
| Heat resistance | Low | Medium | High | Low |
| Fumes | Low | Low | Strong | Low |
| Needs enclosure | No | No | Yes | No |
| Best for | Models | Tough parts | Warm parts | Tougher models |
Pick by the job
Pick PLA for models and prototypes. It prints at 200 to 220 °C and costs the least. Pick PETG for tough parts that stay indoors. Pick ABS for parts that face sustained heat. Pick PLA+ for handled models that need more toughness than standard PLA.
Frequently asked
What is the best 3D printer filament?
It depends on the job. PLA for ease, PETG for tough parts, ABS for heat, PLA+ for tougher models. There is no single best.
What filament should a beginner start with?
PLA. It prints cool, sticks to a bare bed, and needs no enclosure. It is the easiest filament to learn on.
Which filament is strongest?
Of these four, ABS and PETG. For real strength and wear, move to nylon. PLA and PLA+ are more rigid but brittle.
Which filament handles heat?
ABS. It holds up to sustained warmth. PLA softens near 60 °C. PLA+ softens near 53 °C. PETG handles brief warmth.
To compare two at a time, see PLA versus PETG or PLA versus PETG versus ABS. For strength, read which filament is strongest.
