Identity
BrandBambu LabUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2S; spec sheet header "H2S & H2S Laser Edition Spec Sheet"[1]UltiMaker S8 3D Printer[2][3]
Release date (announcement and actual shipping)Not documentedLaunched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[3]
Street price (USD; dated snapshot per entry)From $1,199.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,249.00[4]Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[2][3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Single-nozzle machine sharing the H2 body. H2S and H2S Laser Edition are covered by one spec sheet: the Laser Edition adds laser safety windows, the air-assist pump and the 3264x2448 BirdsEye camera, and a plain H2S can be upgraded with a Laser Upgrade Kit. Against the dual-nozzle H2D in the same 492x514x626 mm shell: 30 kg vs 31 kg, 340x320x340 mm single-nozzle volume vs 325x320x325 mm[1][5]Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3]

Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedUnder 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[2][3]
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[7]12 months, extendable to 5 years with an UltiMakerCare plan[2][3]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
