Bambu Lab H2S: power use and running cost
Single-nozzle H2D sibling with the same large heated chamber at a lower price. 340 × 320 × 340 mm build volume, enclosed.
Power figure: measured. Bambu Lab wiki power-consumption table and H2S FAQ: 26 W standby, 200 W average PLA, 330 W PC; rated 1250 W at 110 V (1800 W at 220 V).

Layer heights that suit the Bambu Lab H2S's Z axis
Z moves 0.0400 mm per full step (lead screws driven by belt, 8 mm per motor revolution, 200 steps/rev, 400 steps/mm). Whole multiples of that are "magic" heights: every layer lands on a full step instead of a less accurate microstep.
| Layer height | 0.08 | 0.10 | 0.12 | 0.15 | 0.16 | 0.20 | 0.24 | 0.25 | 0.28 | 0.30 |
|---|---|---|---|---|---|---|---|---|---|---|
| On a full step? | yes | no → 0.12 | yes | no → 0.16 | yes | yes | yes | no → 0.24 | yes | no → 0.32 |
Basis: estimated. Uses the same H2-series Z kit as the H2D (Bambu wiki 'replace Z axis' covers H2D and H2S): three TR8x8 lead screws belt-driven from one motor; 1:1 pulley ratio and 1/16 microstepping assumed. Open in the magic layer height calculator.
Questions about the Bambu Lab H2S
How many watts does the Bambu Lab H2S use?
About 200 W on average while printing PLA, 26 W when idle and up to 1250 W while heating. Bambu Lab wiki power-consumption table and H2S FAQ: 26 W standby, 200 W average PLA, 330 W PC; rated 1250 W at 110 V (1800 W at 220 V).
How much does it cost to run a Bambu Lab H2S for 24 hours?
4.8 kWh, which is $0.82 at $0.17/kWh (US average) or about £1.25 at UK rates.
Does the Bambu Lab H2S use a lot of electricity?
No. Running it 8 hours a day for a month costs roughly $8.16 at US rates — comparable to a desktop computer.
What are the best layer heights for the Bambu Lab H2S?
The Bambu Lab H2S's Z axis moves 0.0400 mm per full motor step (8 mm per revolution, 200 steps). Layer heights that are whole multiples of that — 0.08, 0.12, 0.16, 0.2, 0.24, 0.28, 0.32 mm — avoid microstep rounding. 0.1, 0.15, 0.25 mm are not exact multiples.
