Bambu Lab H2S vs Bambu Lab H2D
- The H2S has 9% more build volume (37.0 L against 33.8 L).
- Per litre, the H2S is the cheaper space at $34 against $56.
- Only the H2D publishes a flow rate (40 mm³/s, roughly 500 mm/s of line speed), so the other's speed claim cannot be checked.
Bambu Lab
H2S

Bambu Lab
H2D
~$1,899 · 33.8 L
Multi-material and multi-colour work at size, where purge waste and chamber heat both matter.
