What temperature should I print TPU on the Bambu Lab H2D?

Start at 225°C for the hotend and 45°C for the bed, then run a temperature tower across 210–235°C to dial in your exact filament brand.

What print speed works for TPU on this printer?

Around 70 mm/s is a safe starting point on the Bambu Lab H2D. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 0.6 mm of retraction (direct drive needs very little). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for TPU on the Bambu Lab H2D?

No, TPU prints fine in the open on the Bambu Lab H2D.

TPU settings for the Bambu Lab H2D

Great match

⚡ Quick answer: Print TPU on the Bambu Lab H2D at 225°C hotend, 45°C bed, 70 mm/s, 40% part-cooling fan and 0.6 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing TPU on the Bambu Lab H2D. The Bambu Lab H2D has a direct-drive extruder with an all-metal hotend, so we set the hotend to 225°C and the bed to 45°C. TPU is a rubber-like flexible filament; slow speeds and direct drive give the best results.

Troubleshooting TPU on the Bambu Lab H2D

Problem	Fix
Stringing or fine hairs	Dry TPU before printing, drop the hotend a few degrees below 225°C, and raise retraction toward 1.0 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	Clean bed; glue usually not needed. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 0.6 mm. Keep the part-cooling fan low so layers bond and warping stays down.
