| Property | Snapmaker J1sIDEX | UniFormation GKtwoRESIN |
|---|---|---|
| Identity | ||
| Brand | Snapmaker | UniFormation |
| Class | IDEX | RESIN |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Snapmaker J1S High Speed IDEX 3D Printer[1][2] | UniFormation GKtwo 10.3" 8K Resin Printer[3][4] |
| Street price (USD; dated snapshot per entry) | $1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, checked Aug 2026[1] | $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) | The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[1][2] | 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] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 200 x 200 mm in default and backup modes[1] | 228 x 128 x 245 mm[3][4] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 539 x 401 x 464 mm[1] | 350 x 315 x 455 mm[3][4] |
| Net weight (kg) | 25 kg net[1] | 20 kg packaged (UniFormation publishes package weight, not net weight)[3][4] |
| Frame construction & material | Aluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[2] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Not documented | Open-frame MSLA with a UV-blocking cover[3][4] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | IDEX — two independently driven extruders[1][2] | MSLA — photocuring LCD, single Z axis, straight-lift peel[3][4] |
| X-axis guide type (rods / linear rails / V-wheels; size) | Linear rails[2] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 350 mm/s maximum (manufacturer claim)[2] | Not documented |
| Max acceleration (claimed, mm/s²) | 10,000 mm/s2 maximum (manufacturer claim)[2] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 °C maximum (manufacturer claim)[1][2] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 °C maximum (manufacturer claim)[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Custom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[1][2] | Not documented |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | 3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[2] | Not documented |
| Electronics & Power | ||
| Host computer (SoC, RAM, storage) if firmware runs on embedded Linux | 1 GB RAM, 8 GB eMMC; the 5-inch display runs Android[1] | Not documented |
| Input voltage (110/220 V, switch or auto) | AC 100-240 V, 50/60 Hz, 4.4 A max input; DC 24 V, 400 W max output[1] | 110/220 V[3][4] |
| Total rated power draw | 400 W maximum output[1] | Not documented |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[1] | Not named. Slicers: CHITUBOX, the GKtwo slicer, and Lychee. File format STL[3][4] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch Android display, 1280 x 720[1] | 5-inch touchscreen (control panel — not the masking LCD, see W1)[3][4] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB cable, USB flash drive[1] | USB file transfer[3][4] |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[1] | 402.5-405 nm photopolymer resin. No closed compatibility list published[3][4] |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Less than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[1] | Not documented |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | Printing tolerance +/-0.1 mm for lengths up to 100 mm, +/-0.1% beyond — a manufacturer specification, not an independent measurement[3] |
| Resin & MSLA | ||
| Masking LCD | Not documented | 10.3-inch masking LCD, 7680 x 4320 px (8K), XY pixel pitch 29.6 um (manufacturer specification)[3][4] |
| Light source | Not documented | Photocuring LCD light engine at 402.5-405 nm. UniFormation does not publish the LED count or optical design on this page[3][4] |
| 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] |
| Fume extraction | Not documented | Built-in odour filter[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.
