| Class | COREXY | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[1][2] | QIDI X-Plus 3, listed in QIDI navigation as X-Plus3[3][4] |
| 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][5] | Not published by QIDI on the pages checked (Aug 2026)[3][4] |
| 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] | $699 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026. 3DJake lists the model as sold out[4][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][5] | Two headline-speed figures circulate for this model: QIDI's own US page says 600 mm/s and 35 mm3/s, 3DJake's spec table says <=500 mm/s and 30 mm3/s. This is exactly the kind of sibling contamination the 3-series suffers (X-Max 3 is 600 mm/s / 35 mm3/s). Siblings: X-Max 3 (325x325x315, 900 W) and X-Smart 3 (175x180x170, no chamber heat, 300 °C)[3][4][6][7] |
| Market position: superseded? successor announced? | Current large-format flagship as of Aug 2026; QIDI's X-Max 3 page directs buyers here[1][5] | Not documented |
| Physical & Frame | ||

| Frame construction & material | Enclosed CoreXY chassis; QIDI does not publish a frame-material breakdown[1] | All-metal frame per QIDI's US page; no further breakdown published[4] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a 3-in-1 air filter (G3 pre-filter + H12 HEPA + coconut-shell activated carbon)[2] | Fully enclosed with a heated chamber[3][4] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | 65 °C, independent active chamber heating (manufacturer claim), with a 4-pin PWM chamber fan with RPM feedback[2] | 65 °C, independent chamber heating (manufacturer claim)[3][4] |

| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 800 mm/s (manufacturer claim, maximum)[2] | Conflicting manufacturer claims: QIDI's US page says 600 mm/s, 3DJake's spec table says <=500 mm/s. The lower, more conservative figure is used as the sortable value[3][4] |
| Max acceleration (claimed, mm/s²) | 30,000 mm/s2 (manufacturer claim, maximum)[2] | 20,000 mm/s2 (manufacturer claim)[4] |
| Max volumetric flow claimed (mm³/s) | 40 mm3/s rated flow (manufacturer claim)[2] | Conflicting: 30 mm3/s (3DJake) vs 35 mm3/s (QIDI US page). Lower figure used[3][4] |

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.
