| Class | COREXY | COREXY |
| 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] | QIDI X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[2][3] |
| Release date (announcement and actual shipping) | Not documented | Not published by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[2] |
| 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] | $899.00 (from a $999.00 sale reference) on us.qidi3d.com but marked Sold Out and discontinued, checked Aug 2026. 3D Printers Online Store lists $1,099 USD, also out of stock[2][5] |
| 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][6] | Same-generation siblings X-Plus 3 (280x280x270, 500 mm/s, 800 W) and X-Smart 3 (175x180x170, no chamber heating, 300 °C, 350 W). All three share the Cortex-A53 1.5 GHz / 1 GB DDR3 / 8 GB eMMC control board, so shared-board specs are not evidence of shared print specs. Replaced by the Max4[3][7][8][9] |

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.
