Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Original Prusa MINI+ Semi-assembled 3D Printer[1]Raise3D Pro3 3D Printer[2][3]
Street price (USD; dated snapshot per entry)$508.33 on prusa3d.com, Aug 2026[4]$2,999.00 on Raise3D's own store, available, checked Aug 2026[3]
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]A crowded family with materially different prices: Pro3 $2,999, Pro3 Hyper Speed Package $4,999, Pro3 HS $4,599, Pro3 Plus HS $6,099. Build volume also changes with head count: 300 x 300 x 300 mm single-head, 255 x 300 x 300 mm dual-head. Raise3D's smaller E-series (E2 $1,999, E2CF $2,499, E3 $2,499) and the resin DF2 line are separate machines entirely[3][6][2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable180 x 180 x 180 mm (manufacturer figure)[1]300 x 300 x 300 mm with one extruder; 255 x 300 x 300 mm with both[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]620 x 626 x 760 mm[2]

Speed & Acceleration
Max travel speedNot documentedPrint-head travel speed 30-150 mm/s (manufacturer figure)[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]Dual print heads, 1.75 mm filament[2]
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 nozzle temperature[2]
Stock nozzle size & sizes included in boxNot documented0.4 mm default; 0.2, 0.6, 0.8 and 1.0 mm available[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C max heatbed temperature[1]120 °C maximum build-plate temperature, silicone heater[2]
Bed surface (material, texture, coating), single/double-sidedRemovable magnetic steel sheets in several surface finishes; heatbed with cold-corner compensation[1]Flexible steel plate with BuildTak[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 levelling with flatness detection[2]
Cooling & Air Handling
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedHEPA filter with activated charcoal[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][7]Motion controller Atmel ARM Cortex-M4 at 120 MHz with FPU; logic controller NXP ARM Cortex-A9 quad-core at 1 GHz[2]
Host computer (SoC, RAM, storage) if firmware runs on embedded LinuxNot documented1 GB RAM, 8 GB onboard flash, embedded Linux[2]

Total rated power drawNot documented600 W 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[7][8]Embedded Linux on the logic controller; slicing is ideaMaker. Firmware base not published[2]

Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Not documentedLive camera fitted; resolution not published[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, nylon, composites and metal/wood-filled grades[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][7]Not documented
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)Not documentedUnder 55 dB(A) while printing, manufacturer figure. 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[9][8]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXYZ step size 0.78125 / 0.78125 / 0.078125 micron (manufacturer specification, not an accuracy measurement)[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.
