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. It has a print volume of 18 cm (7”) cubed, removable spring steel sheets, ethernet and optional Wi-Fi and it’s based on Prusa Research's 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 and see 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 and removable 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 MK3S+ probes the bed in several places and creates a virtual heightmap of the print area. This process ensures that the first layer will always be spot on!

Network Connectivity

The MINI+ comes standard with an ethernet port and optional future ESP Wi-Fi module upgrade which will enable sending files to the printer wirelessly, or download OTA firmware updates. Thanks to future updates you will be able to manage a whole print farm easily.

Safety Features

Every part we use is thoroughly tested in-house. This is why our 3D printers are highly reliable 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 SMT32

More power, more options. Our brand new custom-made 32-bit “Buddy” motherboard with Trinamic 2209 drivers brings more bang for your bucks. It’s capable of nearly everything OctoPrint can do, including farm management software (future firmware update).

Excellent printers

Excellent printers! I just added four more to my classroom bringing the total to 12. My 6th graders are very quick to learn, and they’ve not failed me yet. Printed Solid is easy to work with as well!

Great Lil Printer

I ordered this as a second printer to complement my ever-changing (and prone to sometimes breaking) tinker-printer formerly known as an Ender 3V2. Everything has been working well, using PrusaSlicer and the default profiles I can get good prints without much effort and great prints with just a bit of calibration. Very satisfied so far!

Highly recommend they are great little machines and the price is right.

We ordered 2 of these for our Jr High and Highschool STEM Classes and they are using them non stop 5 days a week with no issues. I would highly recommend them to anyone looking to either get into 3d printing or if you are looking to build out your farm. Thank you again to Tony Dave and the Printed Solid Crew for everything.
