The short answerPLA is the easy, go-to filament.
PLA is the default filament for most 3D printers. It prints cool, sticks to a bare bed, and needs no heated chamber. The Prusament PLA datasheet lists a nozzle of 210 °C with a 10 °C margin.
What PLA is
PLA stands for polylactic acid, a polyester made from plant starch. It is rigid, prints clean, and comes in the widest color range of any filament. The trade is heat: PLA softens near 60 °C, so it fails in warm environments.
Settings at a glance
These ranges come from the Prusament and Overture PLA datasheets.
| Setting | Recommended | Why |
|---|---|---|
| Nozzle temperature | 200 to 220 °C | Prusament 210 ±10, Overture 190 to 220. |
| Bed temperature | 40 to 60 °C | A heated bed helps the first layer stick. |
| Part cooling fan | 100 % | Full cooling for crisp overhangs. |
| Print speed | 40 to 60 mm/s | Overture lists 40 to 70 mm/s. |
Where PLA fits
- Pick PLA for models, miniatures, and prototypes.
- Pick PLA for parts that stay at room temperature.
- Skip PLA for warm, load-bearing, or outdoor parts.

| Ease of print | Easy | Easy | Medium |
| Toughness | Low | Medium | High |
| Heat resistance | Low | Low | Medium |
| Nozzle temperature | 200 to 220 °C | 210 to 230 °C | 240 to 260 °C |

Common PLA problems
| Likely cause | Fix | Severity |
|---|---|---|
| Warping on a cold bed | Raise the bed to 60 °C and clean the sheet | md |
| Stringing | Drop the nozzle 5 °C and add retraction | lo |
| Poor overhangs | Set the part cooling fan to 100 % | md |
| Brittle parts | Switch to PLA+ for more impact resistance | lo |
Key takeaways
- PLA prints at 200 to 220 °C with the bed at 40 to 60 °C.
- Run the part cooling fan at 100 %.
- PLA softens near 60 °C, so skip it for warm parts.
- For tougher prints, move to PLA+ or PETG.
Frequently asked
What does PLA stand for?
Polylactic acid. It is a polyester made from plant starch, and it is the most common desktop 3D-printing filament.
Is PLA easy to print?
Yes. PLA prints cool, sticks to a bare bed, and needs no heated chamber. It is the best filament for beginners.
Does PLA melt in a hot car?
Yes. PLA softens near 60 °C. A part left in a hot car will warp. Use PETG or ABS for warm environments.
Is PLA stronger than PETG?
No. PLA is more rigid but brittle. PETG is tougher, less brittle, and handles impact and heat better.
