| Property | Prusa CORE One L+COREXY | Snapmaker U1TOOLCHANGER |
|---|---|---|
| Identity | ||
| Brand | Prusa Research | Snapmaker |
| Class | COREXY | TOOLCHANGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Prusa CORE One L+[1] | Snapmaker U1 3D Printer[2] |
| Release date (announcement and actual shipping) | The CORE One L+ refresh was announced on 13 August 2026 and went on sale immediately, with the first assembled units shipping at once; it adds GT1.5 belts and an integrated nozzle wiper to the CORE One L[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $1,850.93 on prusa3d.com, Aug 2026; $1,925.00 with the Advanced Filtration bundle. Prusa's own comparison text on the CORE One+ page quotes "from $1,799", which does not match the live e-shop price[4][5] | $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) | Larger sibling of the CORE One+ (Gen 2): 300 x 300 x 330 mm against 250 x 220 x 270 mm, 60 C chamber against 55 C, 21.9 kg against 22.5 kg (the L is the lighter of the two despite being larger). A CORE One L to CORE One L+ upgrade kit exists, so "CORE One L" and "CORE One L+" are different revisions. A Critical Infrastructure Edition is also listed[1][5][4] | 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 | 300 x 300 x 330 mm, which Prusa states as 29.7 litres[1] | 270 x 270 x 270 mm[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 469 x 521 x 635 mm[1] | 584 x 499 x 730 mm[2] |
| Net weight (kg) | 21.9 kg (48.3 lb)[1] | 18.2 kg[2] |
| Enclosure: open / enclosed; panel material; door/lid | Fully enclosed with a chamber door-open sensor and an active convection heated chamber up to 60 C; advanced filtration is an optional add-on[1] | Open as sold; a top cover is an optional accessory that raises the supported material range[2] |
| Passive chamber temperature reached (if enclosed; measured values preferred) | Active convection chamber heating, maximum 60 C (manufacturer figure)[1] | Not documented |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | CoreXY - stated in Prusa's CORE One+ comparison table[5] | Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[2] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic drivers on the custom xBuddy mainboard (Prusa's CORE One L+ specification says "custom 32-bit xBuddy mainboard with STM32 processor & Trinamic drivers"; it does not give the driver part number)[1] | Not documented |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | Not documented | 500 mm/s maximum toolhead speed (manufacturer claim)[2] |
| Max acceleration (claimed, mm/s²) | Not documented | 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) | Input Shaper and Phase Stepping with an integrated accelerometer[1] | 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 | Nextruder direct drive with a 10:1 planetary gear system; all-metal hotend with an aluminium heatsink and a tool-free quick-swap nozzle system[1] | Not documented |
| Gear ratio & drive gear material | 10:1 planetary gearbox[1] | Not documented |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | Tool-free quick-swap nozzle system; Prusa brass high-flow CHT 0.4 mm pre-mounted plus an abrasive-resistant 0.4 mm nozzle in the box[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 290 C claimed max nozzle temperature. The optional HT hotend that raises this to 400 C was announced for September 2026 availability, so it is not a shipping specification as of Aug 2026[1][3] | 300 °C maximum (manufacturer claim)[2] |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Not documented | Stainless steel as standard; hardened steel needed for fibre-filled grades[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 120 C max heatbed temperature[1] | 100 °C maximum (manufacturer claim)[2] |
| Bed surface (material, texture, coating), single/double-sided | Magnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[1] | Flexible steel sheet with a PEI surface[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | High-precision load-cell sensor - fully automatic first-layer calibration and mesh bed levelling restricted to the print area[1] | Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2] |
| Filament Handling & Detection | ||

| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Custom 32-bit xBuddy mainboard with an STM32 processor[1] | Not documented |
| Total rated power draw | Standby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[1] | Maximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[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.
