| Property | Positron V3.2COREXY | UltiMaker S7INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Positron3D | UltiMaker |
| Class | COREXY | INDUSTRIAL |
| 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] | UltiMaker S7[2] |
| Street price (USD; dated snapshot per entry) | Not documented | $5,999.00 for the standard model at 3D Universe, in stock, 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] | 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)[2][3][4] |
| Market position: superseded? successor announced? | Not documented | Superseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[4][5] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 330 x 240 x 300 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] | 495 x 585 x 780 mm with the spool holder[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | Not documented |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Fully assembled professional chassis[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 250 mm/s maximum print speed (manufacturer claim)[1] | Not documented |
| Max acceleration (claimed, mm/s²) | 8,000 mm/s2 (manufacturer claim)[1] | Not documented |
| Max volumetric flow claimed (mm³/s) | Not documented | Build speed under 24 mm3/s (manufacturer figure)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Dual extrusion with swappable print cores[2] |
| Filament diameter | Not documented | 2.85 mm[2] |
| 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] | 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[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Plated copper[1] | Not documented |
| 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] | PEI-coated flexible build plate, 20-140 °C[2] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | PEI-coated flexible build plate[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 |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Not documented |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi 2.4 GHz and 5 GHz, LAN, USB[2] |
| Calibration Routines & QoL | ||
| Assembly level & time from unbox to first print | Self-assembly kit, manufactured in China[1] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA and PETG only, per the manufacturer[1] | Not documented |
| Noise & Power Consumption | ||
| Noise: claimed dB and independently measured dB (distance/method) | Not documented | Under 50 dBA operating sound, manufacturer figure. No independent measurement[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[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.
