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 (190–220°C), that lands us at 205°C nozzle and 60°C bed. PLA is the easiest filament to print and the best starting point for any printer.

Quick answer: 205°C nozzle · 60°C bed · 60 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 190–220°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 the least fussy filament to buy: almost any brand prints well between 195–215°C. Budget spools run slightly cooler and can be brittle; premium "matte" and "tough" PLAs often like 5–10°C more. The biggest quality difference between cheap and premium PLA is diameter consistency, which shows up as wall-thickness variation more than as a temperature change.

🔎 PLA’s real weakness is heat, not strength — a PLA part left in a hot car or sunny window will sag around 55–60°C. If a part needs to survive heat, that’s the signal to move to PETG or ABS rather than just printing PLA hotter.

Popular PLA brands: eSUN, Overture, Polymaker, Prusament.

Common PLA problems on the Prusa MINI+

SymptomLikely causeFix
Stringing / fine hairsNozzle a touch hot or slightly damp spoolDrop 5°C and raise travel speed before touching retraction distance.
Part warps or lifts cornersDraft or dirty plate (rare for PLA)Clean the plate with soap and water, add a brim, close nearby windows.
Brittle, snaps on the spoolOld or moisture-aged PLADry at 45°C for 4–6 h; store with desiccant afterwards.

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 205°C for the hotend and 60°C for the bed, then run a temperature tower across 190–215°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 60 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.
