PVA settings for the Creality Ender 3 S1 Pro

✓ Great match Advanced Support

These are hardware-tuned starting settings for printing PVA on the Creality Ender 3 S1 Pro. The Creality Ender 3 S1 Pro 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 PVA's ideal range (185–215°C), that lands us at 200°C nozzle and 60°C bed. PVA dissolves in water for clean supports but is very moisture-sensitive and must stay dry.

Quick answer: 200°C nozzle · 60°C bed · 30 mm/s · 1 mm retraction · 50% 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 185–215°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 Creality Ender 3 S1 Pro.

PVA brands & what to expect

PVA is a dissolvable support material that pairs with PLA. Brands differ in how cleanly they dissolve and how quickly they absorb moisture — and all of them are extremely moisture-sensitive.

🔎 PVA that has sat out in humid air turns to jelly in the nozzle and clogs. Keep it sealed with desiccant and only open it to print; treat any printing trouble as a moisture problem first.

SymptomLikely causeFix
Clogs / stringingAbsorbed moistureDry thoroughly and print from a sealed box.
Supports won’t dissolve cleanlyWater too cold / not enough timeUse warm water and agitation; allow more soak time.

On the Creality Ender 3 S1 Pro specifically: its direct-drive extruder needs little retraction, so tune retraction to the hardware rather than copying a random online profile.

FAQ

What temperature should I print PVA on the Creality Ender 3 S1 Pro?
Start at 200°C for the hotend and 60°C for the bed, then run a temperature tower across 185–210°C to dial in your exact filament brand. Our temperature tower planner builds the tower for you.
What print speed works for PVA on the Creality Ender 3 S1 Pro?
Around 30 mm/s is a safe starting point. Check your real speed ceiling with the max volumetric flow calculator.
What retraction should I use for PVA?
Use about 1 mm of retraction (direct drive needs very little). If you see stringing with PVA, raise retraction speed before distance and dry the filament first.
Do I need an enclosure for PVA on the Creality Ender 3 S1 Pro?
No, PVA prints fine in the open on the Creality Ender 3 S1 Pro.
Do I need a hardened nozzle for PVA?
No. PVA is not abrasive, so the stock brass 0.4 mm nozzle on the Creality Ender 3 S1 Pro is fine.
