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 500 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]Dual-extruder counterpart to the single-extruder ARGO 350. Differences that show in a spec box: 500 mm cube vs 350 x 300 x 300, 1700 kg vs 1200 kg, 11-inch vs 7-inch screen, 0.4 and 0.6 mm nozzles vs 0.4 mm only. Nozzle and chamber temperatures are identical on both. Pricing note: Not published. Top 3D Shop lists it 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 usable180 x 180 x 165 mm[1]500 x 500 x 500 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]1935 x 1436 x 2375 mm[2]
Net weight (kg)3 kg net; 5.5 kg with the hard case[1]1700 kg[2]
Frame construction & materialFolding 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/lidOpen frame[1]Enclosed[2]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documented180 °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, dual extruder[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 nameBowden-style, single extrusion[1]Two extruders, 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 boxNot documented0.4 and 0.6 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 limit85 °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-sidedHeated 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]

Calibration Routines & QoL
Assembly level & time from unbox to first printSelf-assembly kit, manufactured in China[1]Not documented
Materials Support
Officially supported filament listPLA 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 documentedXY accuracy 0.01 mm, Z accuracy 0.025 mm (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.
