PLA settings for the Prusa MK3S+
A starting profile for printing PLA on the Prusa MK3S+ (250 × 210 × 210 mm, open frame, direct drive). Tune from here with a temperature tower and a flow test.
| Setting | Starting value |
|---|---|
| Nozzle temperature | 190–220 °C (start 205) |
| Bed temperature | 50–60 °C (start 55) |
| Print speed | 80 mm/s |
| First layer speed | 20 mm/s |
| Layer height | 0.2 mm (0.12–0.28) |
| Retraction distance | 0.6 mm |
| Retraction speed | 30 mm/s |
| Part cooling fan | 100% |
| Enclosure | Open |
| Drying before use | 45 °C for 4 h |
This is a well-matched combination: the printer meets the material's requirements without compromise.
Why these values
The Prusa MK3S+ is a direct-drive machine, so retraction can stay short (around 0.6 mm). Its usable speed is around 80 mm/s, so the 80 mm/s above is capped to what the machine handles comfortably.
Cooling is set to 100%: this material needs strong cooling for detail and overhangs.
Next steps
- Print a temperature tower across 190–220 °C and pick the cleanest band.
- Calibrate flow, then check the volumetric flow against your hotend.
- If something goes wrong, see the troubleshooting guide.
- Price the part with the cost calculator.
