POM with H2D?

Bambu Lab H2 Series

Anyone tried POM with H2D?
I have 1kg that I will try out with a CFX plate + Magigoo PPGF.

Never tried it but it looks like a nightmare. I’m assuming you mostly want POM for the lubricity?

That’s one quality I really appreciate. For now, though, it’s purely experimental — and definitely a fun challenge!

i am also interested in this, but i doubt that the 120 degree bed temperature will be enough for pom. i would also be interested in information about successful prints with the h2d…

As soon as I have the glue and filament I will let you know

I’ve had some time to experiment with POM.

Setup

  • Printer: H2D
  • Build plate: Darkmoon CFX
  • Adhesive: Magigoo Supergrip
  • Chamber temp: 65°C

This spool (and likely other POM) is extremely temperature-sensitive and prone to warping, so I ran extensive tests.

Findings

  • The build plate must be at 120 °C and soaked for at least 10 minutes to get reliable first-layer adhesion.
  • I run layers with the first layer at 240 °C and subsequent layers at 225 °C. This maintains strong layer bonding and helps minimize in-print warping.
  • To eliminate post-print warping and keep parts perfectly flat, I use a step-down bed cooling sequence after completion. My latest test is a bit extreme, but it does produce a flat surface with no warp.
  • I use a 25 mm brim. It could probably be smaller, but I prioritize a warp-free, strong part over skipping brim/glue.

Post-print G-code (placed in the filament “end G-code” section)
Note: this is an aggressive cool-down schedule. It can likely be shortened, but again, the priority here is a strong, warp-free result.
