Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa MINI+ Semi-assembled 3D Printer[1]Snapmaker J1S High Speed IDEX 3D Printer[2][3]
Street price (USD; dated snapshot per entry)$508.33 on prusa3d.com, Aug 2026[4]$1,399.00 at MatterHackers, listed as currently unavailable with a pre-order option quoting roughly 5 weeks, 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][5]The J1s differs from the original J1 by an additional part-cooling fan. Usable volume depends on the print mode: 300 x 200 x 200 mm in default and backup modes, 160 x 200 x 200 in copy mode, 150 x 200 x 200 in mirror mode[2][3]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 180 mm (manufacturer figure)[1]300 x 200 x 200 mm in default and backup modes[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]539 x 401 x 464 mm[2]
Net weight (kg)4.5 kg without spool holder and external PSU[1]25 kg net[2]
Frame construction & materialNot documentedAluminium-alloy frame with one-piece die casting and linear rails; Snapmaker quotes rail repeatability of +/-0.03 mm in X/Y and +/-0.02 mm in Z[3]
Enclosure: open / enclosed; panel material; door/lidOpen frame; sold with an optional Enclosure bundle[1]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Not documentedIDEX — two independently driven extruders[2][3]
X-axis guide type (rods / linear rails / V-wheels; size)Not documentedLinear rails[3]
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 documented350 mm/s maximum (manufacturer claim)[3]
Max acceleration (claimed, mm/s²)Not documented10,000 mm/s2 maximum (manufacturer claim)[3]
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][3]
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]Custom dual-sided PEI glass plate: glossy glass on one face, PEI coating on the other[2][3]
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]3-point bed levelling, which Snapmaker contrasts with 9-16 point systems; assisted calibration quoted at about 10 minutes[3]
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][6]Not documented
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documented1 GB RAM, 8 GB eMMC; the 5-inch display runs Android[2]
Input voltage (110/220 V, switch or auto)Not documentedAC 100-240 V, 50/60 Hz, 4.4 A max input; DC 24 V, 400 W max output[2]
Total rated power drawNot documented400 W maximum output[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[6][7]Not named by Snapmaker; the supplied slicer is Luban, with third-party software supported[2]
Connectivity, UI & Camera
Display: size, type, touch?2.8-inch 65k-colour graphic screen with G-code preview[1]5-inch Android display, 1280 x 720[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, USB cable, USB flash drive[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
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]PLA, ABS, HIPS, PC, TPU, TPE, PETG, ASA, PP, PVA, PA, PA-GF, PA-CF[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][6]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedLess than 50 dBA claimed by the manufacturer. No independent measurement; distance and method not stated[2]
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[8][7]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.
