| Property | Positron V3.2COREXY | Snapmaker U1TOOLCHANGER |
|---|---|---|
| Identity | ||
| Brand | Positron3D | Snapmaker |
| Class | COREXY | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LDO Positron v3.2 3D Printer Kit, revision v3.2 Rev A[1] | Snapmaker U1 3D Printer[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | The defining trait is the inverted geometry: the print head is below the bed and the machine prints upside down. Sold as a self-assembly kit; the complete printed-parts set is a separate purchase. A hard storage case is included[1] | 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[2] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 270 x 270 x 270 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 200 x 200 x 70 mm folded, 200 x 200 x 270 mm unfolded[1] | 584 x 499 x 730 mm[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 18.2 kg[2] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Not documented |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Open as sold; a top cover is an optional accessory that raises the supported material range[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | 500 mm/s maximum toolhead speed (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | 20,000 mm/s2 maximum (manufacturer claim)[2] |
| Max volumetric flow claimed (mm³/s) | Not documented | 32 mm3/s maximum hotend flow (manufacturer claim)[2] |
| 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[2] |
| Extrusion Pressure Control | ||
| Pressure advance (Klipper) / linear advance (Marlin) supported? | Not documented | Pressure advance, with automatic flow compensation calibration[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | PS plated-copper nozzle, 0.4 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 260 °C maximum (manufacturer claim)[1] | 300 °C maximum (manufacturer claim)[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Plated copper[1] | Stainless steel as standard; hardened steel needed for fibre-filled grades[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 85 °C maximum bed temperature — the lowest in this group, and the reason the material list stops at PETG[1] | 100 °C maximum (manufacturer claim)[2] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Flexible steel sheet with a PEI surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Not documented | Filament run-out detection, plus air-printing detection and RFID filament recognition[2] |
| 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[2] |
| Cooling & Air Handling | ||
| Part-cooling fan(s): count, size, ducting design | Not documented | Main plus auxiliary part-cooling fans[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | LDO Positron mainboard[1] | Not documented |
| PSU (brand, wattage, rail voltage) | DC 24 V, 200 W[1] | Not documented |
| Total rated power draw | Not documented | Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Klipper[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 3.5-inch, 320 x 480 touchscreen[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Not documented | 2 MP built-in chamber camera for live view[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Not documented |
| 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[2] |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[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[2] |
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.
