| Property | QIDI X-Max 3COREXY | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | QIDI | UniFormation |
| Class | COREXY | RESIN |
| 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] | UniFormation GKtwo 10.3" 8K Resin Printer[3][4] |
| 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][5] | $749.99 on uniformation3d.com but marked Sold out, checked Aug 2026 (the page shows a compare-at price of $0.00, i.e. none set)[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][6][7][8] | UniFormation lists GKtwo variants by region and bundle (GKtwo ALL, GKtwo ALL UK) rather than by hardware, so the hardware specification is common; what changes is what ships in the box. Not to be confused with the earlier GKone[3] |
| Market position: superseded? successor announced? | Discontinued and out of production; QIDI directs buyers to the Max4[1] | Not documented |
| Physical & Frame | ||

| Gear ratio & drive gear material | 9.5:1[1] | Not documented |
| 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][5] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | <=120 °C claimed[2][5] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Double-sided flexible magnetic plate (QIDI's "HF" plate)[1][2] | Not documented |
| Leveling & Z-Offset | ||

| Layer exposure times | Not documented | 2-3 s per layer at 0.05 mm layer height (manufacturer figure — one of the few makers here that states the layer height its exposure figure assumes). Sortable value is the midpoint[3][4] |
| Layer height range | Not documented | 0.03, 0.05 and 0.1 mm (three discrete settings, not a continuous range)[3][4] |
| Resin vat & feeding | Not documented | Resin vat capacity 0.7 kg, with built-in resin heating: UniFormation quotes warming to 95 F (35 C) in 8 minutes from 50 F. No auto-refill and no level sensing published[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.
