|---|---|---|

| Brand | LulzBot | Prusa Research |
| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | LulzBot TAZ Pro (LulzBot's own store lists it under Legacy LulzBot printers)[1] | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[2] |
| Street price (USD; dated snapshot per entry) | $4,950.00 on buy.lulzbot.com, in stock, checked Aug 2026[1] | $1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Several TAZ Pro derivatives exist and their specs differ substantially: TAZ Pro S, TAZ Pro XT+, and TAZ Pro Long Bed (282 x 582 x 285 mm, 1.2 mm GammaMaster steel nozzle, 80 °C bed cap, 150 mm/s travel, BLTouch 32-point mesh). The base TAZ Pro is 285 mm cubed with a 0.5 mm hardened-steel nozzle, a 110 °C bed and 300 mm/s travel — do not mix the two spec sets[1][3] | Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[2][4][5][6] |
| Market position: superseded? successor announced? | Not documented | Superseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[5][6] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 285 x 285 x 285 mm[1] | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | Not documented | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[2] |
| Net weight (kg) | Not documented | 7 kg (without spool)[2] |
| Frame construction & material | Open frame; movement on GT2 belts with Igus SST rods and polymer bushings[1] | Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[5] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame; the Original Prusa Enclosure is an optional separate product[5] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Cartesian bedslinger[1] | Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[5] |
| Belts (type, width, e.g. Gates?) | GT2 belt drive[1] | Not documented |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Trinamic TMC2130[1] | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[2] |
| Speed & Acceleration | ||
| Max travel speed | 300 mm/s maximum travel speed (manufacturer figure)[1] | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2] |
| Extruder | ||
| Type (direct drive / bowden) & design name | Pro Dual Extruder tool head — two active-lifting hot ends for true dual-material printing[1] | Direct drive with Bondtech gears and an E3D V6 hotend[2] |
| Filament diameter | 2.85 mm standard, 1.75 mm optional[1] | Not documented |
| Hotend & Nozzle | ||
| Max nozzle temp claimed AND firmware max temp limit (both values) | 290 °C maximum hot end temperature[1] | 300 C claimed max nozzle temperature[2] |
| Stock nozzle size & sizes included in box | 0.5 mm hardened steel[1] | Not documented |
| Stock nozzle material (brass / hardened steel / plated copper / composite tip) | Hardened steel[1] | Not documented |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 °C maximum bed temperature[1] | 120 C max heatbed temperature[2] |
| Bed heater type (DC/AC mains) & wattage | 360 W, 24 V silicone bed heater[1] | Not documented |
| Bed surface (material, texture, coating), single/double-sided | Dual-sided borosilicate glass with PEI film[1] | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[2] |
| Leveling & Z-Offset | ||
| Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe) | Automatic 4-point mesh levelling using a 5 V contact circuit, plus automatic X-axis tramming, Z-offset and backlash compensation[1] | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[2] |
| Mesh grid size (probe point count — firmware evidence) | 4-point mesh[1] | Not documented |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament sensor with both runout and stripping detection[1] | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2] |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | 32-bit Archim 2.2b with Trinamic TMC2130 drivers[1] | EINSY RAMBo 8-bit board, co-developed with UltiMachine[2] |

| Total rated power draw | Not documented | Power consumption 80 W on PLA settings, 120 W on ABS settings[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Marlin[1] | prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025. Updated over USB from a PC[7] |

| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Prusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[5][7] |
| Certifications (UL/ETL/CE/FCC — verify, don't assume) | FCC, CE, RCM, ETL, CSA, OSHWA and WEEE. The OSHWA listing is the open-hardware certification[1] | Not documented |
| Reliability, Support & Ecosystem | ||
| Warranty length & support reputation (evidence, not vibes) | 1 year standard, with extended options. Made in the USA[1] | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[8][9] |
| Independently Measured Performance | ||
| Dimensional accuracy measurements (third-party, with numbers) | Positional resolution 0.01 mm in X/Y and 0.002 mm in Z (manufacturer specification, not an independent measurement)[1] | Not documented |
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.
