PLA+ settings for the Anycubic Kobra 3

✓ Great match Beginner Easy / Everyday

These are hardware-tuned starting settings for printing PLA+ on the Anycubic Kobra 3. The Anycubic Kobra 3 pairs a direct-drive extruder with an all-metal hotend on an open frame, and tops out at 300°C hotend / 110°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 · 77 mm/s · 0.8 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 direct-drive Anycubic Kobra 3.

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 Anycubic Kobra 3

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 Anycubic Kobra 3 specifically: it is a fast machine, so if PLA+ looks rough, drop speed before blaming temperature — many "quality" issues here are really the hotend not keeping up with the flow.

FAQ

What temperature should I print PLA+ on the Anycubic Kobra 3?
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 Anycubic Kobra 3?
Around 77 mm/s is a safe starting point. This printer can go faster once the profile is tuned, but start conservative for clean walls. Check your real speed ceiling with the max volumetric flow calculator.
What retraction should I use for PLA+?
Use about 0.8 mm of retraction (direct drive needs very little). 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 Anycubic Kobra 3?
No, PLA+ prints fine in the open on the Anycubic Kobra 3.
Do I need a hardened nozzle for PLA+?
No. PLA+ is not abrasive, so the stock brass 0.4 mm nozzle on the Anycubic Kobra 3 is fine.
