Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Prusa CORE One L+[1]Original Prusa MINI+ Semi-assembled 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]$508.33 on prusa3d.com, Aug 2026[4]
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]Sold semi-assembled and, historically, as a kit; also offered in an Enclosure Bundle. Distinguish from the larger i3-family machines - the MINI+ is Bowden-fed with 2209 drivers, a 280 C nozzle ceiling and a 100 C bed, all lower than the MK3S+/MK4S. Note that Prusa's own MINI+ page carries an "Awards & Press Reviews" paragraph that is entirely about the MK3S, not the MINI+[2][6]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable300 x 300 x 330 mm, which Prusa states as 29.7 litres[1]180 x 180 x 180 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)469 x 521 x 635 mm[1]380 x 330 x 380 mm (X x Y x Z), stated without the spool holder and external PSU - the external PSU brick needs additional desk space[2]
Net weight (kg)21.9 kg (48.3 lb)[1]4.5 kg without spool holder and external PSU[2]
Enclosure: open / enclosed; panel material; door/lidFully 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 frame; sold with an optional Enclosure bundle[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]Not documented
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]Trinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Input Shaper and Phase Stepping with an integrated accelerometer[1]Not documented
Extruder
Type (direct drive / bowden) & design nameNextruder 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]Bowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[2]
Gear ratio & drive gear material10:1 planetary gearbox[1]3:1 extruder gearing[2]
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]280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C max heatbed temperature[1]100 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedMagnetic heatbed with removable dual-sided PEI spring-steel sheets; a satin powder-coated sheet is supplied[1]Removable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[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]SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[2]
Filament Handling & Detection
Filament runout sensor (type, location)Two filament sensors, plus a chamber door-open sensor and five Semitec thermistors[1]Not documented
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Custom 32-bit xBuddy mainboard with an STM32 processor[1]Custom 32-bit board of Prusa's Buddy family; the MINI/MINI+ is covered by the same Prusa-Firmware-Buddy source tree as the MK4, XL and CORE One. The exact board revision is not given on the product page[2][7]
Total rated power drawStandby 16 W, preheating about 630 W, average printing about 90 W on PLA and about 215 W on ASA (manufacturer figures)[1]Not documented

Safety
Thermal runaway protection (verify in firmware source if at all possible)Open-source firmware on the xBuddy platform, which carries hardware overcurrent protection cutting heater and heatbed power above 15 A[9][7]Three thermistors and fan RPM sensors are fitted, and the firmware is open-source and auditable (Prusa-Firmware-Buddy); Prusa does not describe the thermal-runaway implementation on the product page[2][7]
Reliability, Support & Ecosystem

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.
