|---|---|---|
| Identity | ||
| Brand | QIDI | Snapmaker |
| Class | COREXY | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[1][2] | Snapmaker U1 3D Printer[3] |
| Release date (announcement and actual shipping) | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[1][4] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[1] | $849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[1][4] | An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[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.
