| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Snapmaker J1S High Speed IDEX 3D Printer[1][2] | Snapmaker U1 3D Printer[3] |
| 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] | $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) | 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] | 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] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 300 x 200 x 200 mm in default and backup modes[1] | 270 x 270 x 270 mm[3] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 539 x 401 x 464 mm[1] | 584 x 499 x 730 mm[3] |
| Net weight (kg) | 25 kg net[1] | 18.2 kg[3] |
| 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 as sold; a top cover is an optional accessory that raises the supported material range[3] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | IDEX — two independently driven extruders[1][2] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[3] |
| 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] | 500 mm/s maximum toolhead speed (manufacturer claim)[3] |
| Max acceleration (claimed, mm/s²) | 10,000 mm/s2 maximum (manufacturer claim)[2] | 20,000 mm/s2 maximum (manufacturer claim)[3] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s maximum hotend flow (manufacturer claim)[3] |
| Vibration Compensation / Input Shaping | ||
| Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary) | Not documented | Input shaping with an accelerometer, run as a calibration routine[3] |
| Extrusion Pressure Control | ||
| Pressure advance (Klipper) / linear advance (Marlin) supported? | Not documented | Pressure advance, with automatic flow compensation calibration[3] |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 °C maximum (manufacturer claim)[1][2] | 300 °C maximum (manufacturer claim)[3] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Stainless steel as standard; hardened steel needed for fibre-filled grades[3] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 100 °C maximum (manufacturer claim)[1] | 100 °C maximum (manufacturer claim)[3] |
| 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] | Flexible steel sheet with a PEI surface[3] |
| 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] | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[3] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out detection, plus air-printing detection and RFID filament recognition[3] |
| Multi-material/multi-color capability or official upgrade path | Not documented | Four toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[3] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Main plus auxiliary part-cooling fans[3] |
| 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] | Not documented |
| Total rated power draw | 400 W maximum output[1] | Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[3] |
| 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] | Klipper[3] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 5-inch Android display, 1280 x 720[1] | 3.5-inch, 320 x 480 touchscreen[3] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB cable, USB flash drive[1] | Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[3] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | 2 MP built-in chamber camera for live view[3] |
| Power-Loss & Interruption Recovery | ||
| Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?) | Not documented | Power-loss recovery supported; mechanism not published[3] |
| Materials Support | ||
| Officially supported filament list | PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[1] | Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[3] |
| 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 |
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.
