Original Prusa MINI+ - smart and compact 3D printing workhorse with all the bells and whistles you’re accustomed to when you buy an Original Prusa 3D printer. MINI+ will surprise you. :-) It has a print volume of 18 cm (7”) cubed, removable spring steel sheets, ethernet and optional Wi-Fi and it’s based on our brand new custom-made 32-bit Buddy mainboard with silent 2209 Trinamic drivers.
Main Features
Build Volume
Featuring a 7"×7"×7" (18×18×18 cm) build volume, the MINI+ is a fully-equipped 3D printer. Featuring sensorless homing, automatic Mesh Bed Calibration, replaceable nozzles, network connectivity, USB printing and a full-color LCD screen, the MINI+ is a big printer in a small body.
Color LCD Screen
Configure your 3D printer with ease andsee previews of sliced models before you start printing! Thanks to the 2.8’’, 240×320 LCD screen with 65.000 colors, every option is just a few clicks away.
Flexible Print Sheets
Removing a print has never been easier! With the magnetic heatbed andremovable spring steel sheets, you can remove a printed object merely by bending the steel sheet. The surface is easy to maintain and comes in two variants: smooth and textured.
SuperPinda Probe
SuperPINDA probe features a hiqh-quality sensor for a fully-automatic Mesh Bed Leveling process. Before every print, the printer probes the bed in several places and creates avirtual heightmap of the print area. This process ensures that the first layer will always be spot on!
Network Connectivity
The MINI+ comes standard with anethernet port and optional future ESPWi-Fimodule upgrade which will enable sending files to the printer wirelessly, or download OTA firmware updates. Thanks to future updates you will be able tomanage a whole print farm easily.
Safety Features
Every part we use is thoroughlytested in-house. This is why our 3D printers are highlyreliable and safe to use. The MINI+ is equipped with three thermistors and comes with a high-quality power supply (Delta or Mean Well - depending on region) for safe and reliable information.
One-click Printing
Once you insert a USB drive with a sliced object, a new menu with an object preview window appears. Confirm the selection with a single click of the control wheel and watch the printer do the rest for you.
32bit Controller STM32
More power, more options. Our brand new custom-made32-bit “Buddy”motherboard withTrinamic 2209drivers brings more bang for your bucks. It’s capable of nearly everything OctoPrint can do, including farm management software (future firmware update).

Awards & Press Reviews
Thanks to all of these (and many other) features, the MK3S became the “Best 3D Printer” according to ALL3DP. The MK3S is also the highest-rated3D printer, and the “Editor’s Choice”, in the prestigious MAKE:MAGAZINE’s Digital Fabrication Guide 2019. The MK3S is also featured in TechRadar's Best 3D printers of 2021 as The best all-around 3D printer.NY Times wrote that "...of the 11 printers we’ve tested over the past five years, the Prusa i3 MK3S printer has produced the largest and best-looking prints." According to ZDNet, the MK3S is "The best pro-sumer 3D printer under 1000 USD."
I think the MINI is a great machine, especially for the price. You won't find a more complete package of solid hardware, usable firmware, good documentation and great software under 400 bucks.
This small and sturdy machine uses an excellent slicer, comes with a magnificent metal bed and, overall, gives you excellent print quality. It’s difficult to see how anyone could be disappointed with it.
Right out of the box, this thing is so impressive (...) You can get yourself pretty much what I consider to be a top-of-the-line performance printer for 350 USD.
When we weigh up the price, performance, reliability and overall product, it is highly recommended for most people to purchase because it does things so well.
The MINI has become my favorite 3D printer of 2020 (...) it's the out-of-the-box experience: once you assemble it, there's very little else to do to it except for just slice the model and print it.
Prusa have done all they can to pack the features of their best selling 3D printers into a smaller and cheaper package. The Mini may be small but it’s reliable, built to last and delivers excellent print quality just like it’s bigger siblings.
We designed the MINI+ to be a true3D printing workhorse. Thanks to its compact dimensions, you can build an entire print farm to produce mechanical parts at a rapid pace. And the affordable price makes the MINI+ agreat first 3D printer for everyone.
