PLA+ settings for the Prusa MINI+

✓ Great match Beginner Easy / Everyday

These are hardware-tuned starting settings for printing PLA+ on the Prusa MINI+. The Prusa MINI+ pairs a Bowden extruder with an all-metal hotend on an open frame, and tops out at 280°C hotend / 100°C bed. Against PLA+'s ideal range (205–230°C), that lands us at 215°C nozzle and 60°C bed. PLA+ is tougher and less brittle than standard PLA while printing almost as easily.

Quick answer: 215°C nozzle · 60°C bed · 55 mm/s · 5 mm retraction · 100% part fan. Change one setting at a time and validate with a small calibration model.

Calibration order

  1. Dry the spool if it shows moisture symptoms, then confirm the nozzle and build plate are clean.
  2. Print a temperature tower inside the 205–230°C range; pick the lowest temperature with strong layer bonding and clean overhangs.
  3. Calibrate flow, then pressure/linear advance if your firmware supports it.
  4. Tune retraction last — more distance is not always better, especially on the Bowden Prusa MINI+.

PLA+ brands & what to expect

"PLA+" is a marketing name, not a standard, so eSUN PLA+, SUNLU PLA+ and Polymaker PolyTerra all behave a little differently. Most want 5–15°C more than basic PLA to reach full layer strength. Treat the number on the box as a midpoint and tune from there.

🔎 The point of PLA+ is toughness: it flexes a little before it breaks instead of snapping like brittle PLA, which makes it a better pick for brackets, clips and functional prints that still don’t need heat resistance.

Popular PLA+ brands: eSUN, Polymaker, SUNLU, ELEGOO.

Common PLA+ problems on the Prusa MINI+

SymptomLikely causeFix
Weak layer bondingPrinted at basic-PLA temperatureRun a temperature tower 5–15°C hotter than your usual PLA.
StringingHigher temp increases oozeKeep retraction tuned; a small temp drop usually clears it.

On the Prusa MINI+ specifically: its Bowden extruder needs more retraction than a direct-drive machine, so tune retraction to the hardware rather than copying a random online profile.

FAQ

What temperature should I print PLA+ on the Prusa MINI+?
Start at 215°C for the hotend and 60°C for the bed, then run a temperature tower across 205–225°C to dial in your exact filament brand. Our temperature tower planner builds the tower for you.
What print speed works for PLA+ on the Prusa MINI+?
Around 55 mm/s is a safe starting point. Check your real speed ceiling with the max volumetric flow calculator.
What retraction should I use for PLA+?
Use about 5 mm of retraction (Bowden setups need more). If you see stringing with PLA+, raise retraction speed before distance and dry the filament first.
Do I need an enclosure for PLA+ on the Prusa MINI+?
No, PLA+ prints fine in the open on the Prusa MINI+.
Do I need a hardened nozzle for PLA+?
No. PLA+ is not abrasive, so the stock brass 0.4 mm nozzle on the Prusa MINI+ is fine.
