Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa MINI+ Semi-assembled 3D Printer[1]Snapmaker U1 3D Printer[2]
Street price (USD; dated snapshot per entry)$508.33 on prusa3d.com, Aug 2026[3]$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)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+[1][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 usable180 x 180 x 180 mm (manufacturer figure)[1]270 x 270 x 270 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)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[1]584 x 499 x 730 mm[2]
Net weight (kg)4.5 kg without spool holder and external PSU[1]18.2 kg[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame; sold with an optional Enclosure bundle[1]Open as sold; a top cover is an optional accessory that raises the supported material range[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Not documentedFour independent toolheads on a changer; Snapmaker quotes a 5-second swap[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)Trinamic 2209 silent stepper drivers, with sensorless homing on the X and Y axes[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)Not documented500 mm/s maximum toolhead speed (manufacturer claim)[2]
Max acceleration (claimed, mm/s²)Not documented20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control
Pressure advance (Klipper) / linear advance (Marlin) supported?Not documentedPressure advance, with automatic flow compensation calibration[2]
Extruder
Type (direct drive / bowden) & design nameBowden extruder with 3:1 gearing - the only current Prusa FFF machine that is not direct drive[1]Not documented
Gear ratio & drive gear material3:1 extruder gearing[1]Not documented
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)280 C claimed max nozzle temperature - lower than the 290-300 C of the i3-family machines[1]300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedRemovable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[1]Flexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)SuperPINDA inductive probe with no temperature drift, driving automatic mesh bed levelling[1]Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Not documentedFilament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathNot documentedFour toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedMain plus auxiliary part-cooling fans[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)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[1][5]Not documented
Total rated power drawNot documentedMaximum input power 1150 W at 220-240 V, 400 W at 100-120 V; maximum input current 6 A / 4 A respectively[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Open-source Prusa Buddy firmware. The source tree (prusa3d/Prusa-Firmware-Buddy on GitHub) explicitly covers the Original Prusa MINI/MINI+, MK4, XL and CORE One and was last pushed to in August 2026. Updates are applied from a USB drive, through Prusa Connect or through the Prusa mobile app[5][6]Klipper[2]
Connectivity, UI & Camera
Display: size, type, touch?2.8-inch 65k-colour graphic screen with G-code preview[1]3.5-inch, 320 x 480 touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)On-device colour UI with G-code preview; remote print management through Prusa Connect[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB port, RJ-45 Ethernet, optional ESP Wi-Fi module (sold separately); compatible with Prusa Connect[1]Wi-Fi 2.4 GHz (802.11b/g/n) and USB flash drive. No Ethernet listed[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documented2 MP built-in chamber camera for live view[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printSemi-assembled: Prusa ships it in a small number of pre-built sections; also historically sold as a full kit[1]Not documented
Power-Loss & Interruption Recovery
Power-loss recovery: mechanism (how is state saved? capacitor / eeprom / file on shutdown?)Not documentedPower-loss recovery supported; mechanism not published[2]
Materials Support
Officially supported filament listPLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, Woodfill and other filled materials (Prusa's own list; the 100 C bed and open frame are the practical limit for ABS/ASA)[1]Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2]
Safety
Thermal runaway protection (verify in firmware source if at all possible)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[1][5]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)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[7][6]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.
