| Property | Positron V3.2COREXY | UltiMaker S5INDUSTRIAL |
|---|---|---|
| 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 S5 3D Printer[2] |
| Street price (USD; dated snapshot per entry) | Not documented | Starting at $6,950 at MatterHackers, 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] | Three generations share the same 330 x 240 x 300 mm envelope and are easy to confuse: S5 (280 °C nozzle, glass bed to 140 °C, 4.7-inch screen), S7 (PEI-coated flexible plate, Wi-Fi 5 GHz added, $5,999) and S8 (340 °C, 500 mm/s, 50,000 mm/s2, PEI plate to 120 °C). Build-volume figures alone will not tell them apart[2][3][4] |
| Market position: superseded? successor announced? | Not documented | Superseded by the S7 and then the S8, but still sold[2][3][4] |
| 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 assembled with the spool holder[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 20.6 kg[2] |
| 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 an articulating nozzle-lifting print head. UltiMaker does not publish the kinematic layout in this spec table[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-geared feeder rated for advanced composites; 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] | 180-280 °C nozzle temperature range; heat-up under 2 minutes[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm standard; 0.25, 0.6 and 0.8 mm available[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] | Heated glass bed, 20-140 °C[2] |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Heated glass build plate[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Not documented | Automatic advanced levelling; probe technology not stated in this table[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 | 500 W maximum power output[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Klipper[1] | Not published; print preparation is UltiMaker Cura and UltiMaker Essentials[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 4.7-inch colour touchscreen[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | Wi-Fi, Ethernet, 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; distance and method not stated[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification, not an independent measurement)[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.
