The PLA versus PETG choice comes down to what the part does. PLA is easier and looks crisper. PETG is tougher and handles heat.
Side by side
| Property | PLA | PETG |
|---|---|---|
| Ease of print | Easy | Medium |
| Toughness | Low | High |
| Heat resistance | Low | Medium |
| Stringing | Rare | Common |
| Typical nozzle | 200 to 220 °C | 240 to 260 °C |
| Best use | Models, prototypes | Functional parts |
The green row is not a verdict on which filament is better overall. It marks the easier path for a beginner: PLA prints with less tuning, so it wins the ease row.
Frequently asked
Is PETG harder to print than PLA?
Yes, a little. PETG strings more and needs careful retraction and dry storage. PLA is the easier starting point.
Can I swap PLA for PETG without changing settings?
No. PETG needs a hotter nozzle (around 240 to 260 °C) and a hotter bed (70 to 80 °C), plus retuned retraction.
Which is stronger?
PETG. It is tougher and less brittle than PLA, and it holds up better to heat and impact.
For the full settings on each, read the PLA guide and the PETG guide. If stringing is the blocker, the stringing guide walks the fixes.
