| Property | QIDI X-Max 3COREXY | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | QIDI | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | QIDI X-Max 3, listed by QIDI as "Qidi Tech X-Max 3 3D Printer" and in navigation as X-Max3[1][2] | UltiMaker S7[3] |
| Release date (announcement and actual shipping) | Not published by QIDI; the product page carries a discontinuation notice rather than a launch date (checked Aug 2026)[1] | Not documented |
| Street price (USD; dated snapshot per entry) | $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[1][4] | $5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[3] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | 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[2][5][6][7] | Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[3][8][9] |
| Market position: superseded? successor announced? | Discontinued and out of production; QIDI directs buyers to the Max4[1] | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[9][10] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 325 x 325 x 315 mm advertised[1][2][4] | 330 x 240 x 300 mm[3] |

| Z-axis: leadscrew count & type, sync mechanism, anti-backlash | Double Z axis[2] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | <=600 mm/s (manufacturer claim)[1][2][4] | Not documented |
| Max acceleration (claimed, mm/s²) | 20,000 mm/s2 (manufacturer claim)[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | 35 mm3/s extruder flow (manufacturer claim)[2] | Build speed under 24 mm3/s (manufacturer figure)[3] |
| Extruder | ||
| Type (direct drive / bowden) & design name | High-flow direct-drive extruder; QIDI states a 9.5:1 gear ratio for this model[1][2] | Dual extrusion with swappable print cores[3] |
| Gear ratio & drive gear material | 9.5:1[1] | Not documented |
| Filament diameter | Not documented | 2.85 mm[3] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Ceramic heating core. Two interchangeable nozzle-head sets shipped: copper alloy for standard materials, hardened steel for abrasives. 0.4 mm stock, 0.2/0.6/0.8 mm optional[1][2] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | <=350 °C claimed[1][2][4] | Not documented |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed[2][4] | PEI-coated flexible build plate, 20-140 °C[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.
