POM Filament

Acetal / Delrin / Polyoxymethylene

F
Also known as:AcetalDelrinPolyoxymethylene
Family:POM

Why Use POM?

  • Very low friction, stiff, easy to machine (in CNC contexts)
  • Low friction, wear parts, gears, bushings

Things to Consider

  • Near-zero bed adhesion; requires mechanical anchoring to bed surface
  • Layer splitting; needs heated enclosure and very slow printing
  • Heat decomposition can release formaldehyde (high hazard)
  • Often outclassed by nylon for printable low-friction parts

Frequently Asked Questions

What is POM filament?
POM (Acetal / Delrin / Polyoxymethylene) is a 3D printing filament. Very low friction, stiff, easy to machine (in CNC contexts)
What temperature should I print POM at?
POM typically prints at nozzle temperatures of 220-260°C and bed temperatures of 90-120°C. Low cooling
Do I need an enclosure to print POM?
Yes, an enclosure is required for printing POM. Layer splitting; needs heated enclosure and very slow printing
What is POM filament best for?
POM is best for: Very low friction, stiff, easy to machine (in CNC contexts); Low friction, wear parts, gears, bushings.
What are the downsides of POM filament?
The main considerations when using POM: Near-zero bed adhesion; requires mechanical anchoring to bed surface; Layer splitting; needs heated enclosure and very slow printing; Heat decomposition can release formaldehyde (high hazard); Often outclassed by nylon for printable low-friction parts.
