How to Reduce Warping on Prints

Intro
Warping—corners lifting off the bed—ruins flatness and can cause parts to detach entirely. It’s most common with ABS/ASA/Nylon. Here’s how to minimize it.

Why warping happens

  • Plastic shrinks as it cools
  • Bottom layers cool slower than top layers
  • Internal tension pulls corners upward

Quick adhesion fixes

  • Clean bed with isopropyl alcohol
  • Use a fresh build surface (PEI, textured, or glass + glue stick)
  • Add a 5–8 line brim
  • Slow first layer to ~20 mm/s and increase extrusion width
  • Raise bed temp 5–10 °C within safe limits

Environmental control

  • Use an enclosure to stabilize temperature
  • Avoid drafts from fans or open windows
  • Preheat the chamber for tricky filaments

Material choice

  • PLA: rarely warps
  • PETG: minor warping—moderate bed temps help
  • ABS/ASA: enclosure, brim, higher bed temps
  • Nylon: enclosure + glue stick are musts

Design tips

  • Add chamfers or “mouse ears” to corners
  • Reduce sharp corners that concentrate stress
  • Orient parts so large flat faces contact the bed
  • Split very large models into sections

FAQ

Can I stop warping completely? Not always, but you can reduce it to a non-issue.

My part sticks too well—how do I remove it? Let the bed cool; parts often pop off as it contracts.

Wrap-up

Focus on clean surfaces, stable temps, and strong first layers. With these habits, you’ll get flat, reliable prints even with warp-prone materials.
