| Property | Positron V3.2COREXY | Roboze ARGO 350INDUSTRIAL |
|---|---|---|
| Identity | ||
| Brand | Positron3D | Roboze |
| 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] | Roboze ARGO 350 3D Printer[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] | Single-extruder machine; the ARGO 500 is dual-extruder with a 500 mm cube, an 11-inch screen and 1700 kg. Both quote a 450 °C nozzle and a 180 °C chamber, so temperature figures will not tell them apart — extruder count, build size and weight will. Pricing note: Not published. Top 3D Shop lists the machine as available on backorder with a 3-5 week lead time but requires a quote request rather than showing a price, checked Aug 2026[2][3] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 180 x 180 x 165 mm[1] | 350 x 300 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] | 1130 x 1150 x 2000 mm[2] |
| Net weight (kg) | 3 kg net; 5.5 kg with the hard case[1] | 1200 kg[2] |
| Frame construction & material | Folding frame designed to fit in a filament box; supplied with a black hard case[1] | Fully assembled, made in Italy[2] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame[1] | Enclosed[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Not documented | 180 °C chamber temperature (manufacturer specification, actively heated)[2] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY, inverted — the machine prints upside down[1] | CoreXY[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 |
| Extruder | ||
| Type (direct drive / bowden) & design name | Bowden-style, single extrusion[1] | Single extruder, 1.75 mm filament[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] | 450 °C maximum nozzle temperature (manufacturer specification)[2] |
| Stock nozzle size & sizes included in box | Not documented | 0.4 mm[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] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Heated removable ITO glass bed[1] | Removable polymer build sheets held by vacuum[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] | Proprietary; the recommended software is Roboze Prometheus[2] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 3.5-inch LCD touchscreen[1] | 7-inch colour touchscreen[2] |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Wi-Fi, USB, Ethernet[1] | USB, Ethernet, Wi-Fi[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] | PEEK, Carbon PEEK, Carbon PA, ULTEM AM9085F, PC, Functional-nylon, ABS-ESD, PP, Flex-TPU, Strong-ABS, Ultra-PLA and others[2] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Not documented | XY accuracy 0.01 mm, Z accuracy 0.025 mm (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.
