Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Bambu Lab H2D[1]QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[2][3]
Release date (announcement and actual shipping)Not documentedNot published by QIDI on the pages checked (Aug 2026)[2][3]
Street price (USD; dated snapshot per entry)From $1,549.00 on the Bambu Lab US store, Aug 2026, against a stated typical price of $1,749.00; the product page shows $1,749.00 (typical $1,999.00) with a combo variant selected[4][5]$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Six SKUs on one product page including H2D, H2D AMS Combo and H2D Laser Full Combo. The Laser Edition adds laser safety windows and the air-assist pump; a plain H2D can be upgraded with a Laser Upgrade Kit. The BirdsEye camera is only fitted on the Laser Edition. Siblings in the same family are the H2S (single nozzle, 340x320x340 mm, 30 kg) and H2C (dual nozzle, 305x320x325 mm single-nozzle volume, 32.5 kg, four cameras as standard) - all three share the 492x514x626 mm body, so body dimensions alone will not tell them apart[1][6][7]Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[2][8][9]
Market position: superseded? successor announced?Current model; the H2C sits above it in the same body at $2,199 and the H2S below it at $1,199[4]Not documented
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usableSingle-nozzle printing 325 x 320 x 325 mm; dual-nozzle printing 300 x 320 x 320 mm; total volume across the two nozzles 350 x 320 x 320 mm. The sortable figure is the single-nozzle volume[1]175 x 180 x 170 mm advertised[2][3]
Machine footprint (mm) & clearance needed (cable/spool overhang)492 x 514 x 626 mm[1]370 x 362 x 397 mm[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.
