Bambu Lab H2S vs Raise3D Pro3 — documented properties and sources
PropertyBambu Lab H2SCOREXYRaise3D Pro3IDEX
Identity
BrandBambu LabRaise3D
ClassCOREXYIDEX
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]Raise3D Pro3 3D Printer[2][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]$2,999.00 on Raise3D's own store, available, checked Aug 2026[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]A crowded family with materially different prices: Pro3 $2,999, Pro3 Hyper Speed Package $4,999, Pro3 HS $4,599, Pro3 Plus HS $6,099. Build volume also changes with head count: 300 x 300 x 300 mm single-head, 255 x 300 x 300 mm dual-head. Raise3D's smaller E-series (E2 $1,999, E2CF $2,499, E3 $2,499) and the resin DF2 line are separate machines entirely[3][6][2]

Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXYZ step size 0.78125 / 0.78125 / 0.078125 micron (manufacturer specification, not an accuracy measurement)[2]

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.
