Prusa Research, the Czech-based company never ceases to impress users. Time again, it has given individuals the best 3D printers to help them build astonishing models without any hassle.

We have already witnessed successful releases before. Either it was Original Prusa i3 MK3S, its proprietary filament line, Prusament, or its own slicing software, PrusaSlicer, the company has amazed us every time.

This time, it has tried once again to surprise its users with an outstanding 3D printer, known as Original Prusa Mini.

Josef Prusa’s Mini is a smaller version of the MK3S. An even more affordable 3D printer that is no less in terms of providing high-quality print results when compared to its counterparts and even with those holding a higher price tag.

The 3D Printer has already created a buzz after its release at the end of 2019. And, the claims by the company does reveal that the printer would certainly be among the user’s favorites like the others from the Prusa series.

Original Prusa MINI (1)


The 3D printer is a compact version of the prior release by the company, the Original Prusa MK3S, and promises for providing the best in class experience to its users.

Among the features that it flaunts, here are a few of the major ones that have acquired most of the attention from the 3D printing community.

Affordable: It is important to note that the 3D printers are getting cheaper and the features they embody, are growing.

Hence, to keep itself inside the competition, Prusa has come up with this affordable machine that sits back to another affordable Original Prusa i3 MK3S kit in terms of price.

The starting price is $349 which makes it accessible to an even larger number of audiences. With that price point, users may have to compromise with a few of the perks that were available with the predecessor. It offers a smaller build volume.

Magnetic Build Plate: The Mini tries to flaunt the best of its features and keeps the user interested by offering irresistible deals.

One such feature is the removable magnetic build plate with PEI-coated spring steel sheets. The option can be considered as the best among the ones available with the 3D printers currently. It is very helpful in providing easy removal of completed models.

As soon as the sheet cools down, the printed parts pop out only by flexing the sheet inward. There are additional optional purchases are available as well. Pay an extra $30 to buy an upgraded textured powder-coated spring steel sheet. Isn’t that plenty to offer?

Ethernet RJ45 port: The 3D printer is not equipped with WiFi connectivity, however, it provides an ethernet port for its users.

This port is helpful in streamlining the workflows substantially. Hence, a powerful feature added to the machine is anyone who likes to build a Minis print farm.

Color LCD Screen: You would be happy to see the new colorful LCD screen that adds more than the looks to the printer.

Using this screen, users can preview the model after slicing before it is sent for printing. This cool feature may not add a lot of value to a few users, but few would definitely fall for this bait.

Compact size: Many users believe in spending their money on bigger machines. However, there are those users who like the compact ones.

This machine is for those users who prefer a smaller footprint over a huge one. It is compact and can snug easily on your desk without acquiring much space. Hence, a manageable machine that is easily transportable.

Bowden System: This is an upgrade that we were looking forward to. The MK3S has a direct drive extruder. However, in the Mini, the company has included a Bowden system along with the 3:1 drive gear ratio.

The arrangement is helpful in keeping the extruder lightweight. Hence, lessening the problem of wobbling. The design is impressive and the extruder motor finds a place on the Z-axis column in the Mini. The filament is loaded using a PTFE tube and reaches the hotel.

Automatic Bed Leveling: The printer keeps the job easier for the users. It once again has come up with its automatic mesh bed leveling feature making the installation and setup easier for beginners.

32-Bit Controller: The Mini is equipped with a custom-made 32-bit motherboard. It uses the Trinamic 2209 drivers.

This addition, as per the manufacturer’s claim would offer almost every perk that is available with OctoPrint. It would also make farm management software available through a firmware update in the coming future.

The various features the machine embodies have given the 3D printer a completely unique signature of itself. With an aim to reach more audiences, the company has come up with a precise yet most useful feature-packed device.


Prusa Research release of Mini has made those happiest who were waiting for a smaller machine with the goodness of the latest technology.

With a space requirement of 380 x 330 mm, the 3D printer provides a build volume of 180 x 180 x 180 mm. The 3D printer silently is getting into the mainstream by offering amazing precision and accuracy to its users.

It provides a layer height of 0.05 to 0.35 mm. The noteworthy machine comes with a non-removable build plate but a removable PEI spring steel sheet that does the job conveniently.

The extruder can reach a maximum temperature of 280 degrees Celsius offering compatibility for a wider range of filament types. The build plate also is heated and can attain a temperature of 100 degrees Celsius.

The 3D printer does not have a filament sensor inclusion which can be upgraded through additional cost.

Moreover, the WIFI connectivity may soon surface in the future through an upgrade. The promising 3D printer, Mini by Prusa has turned a lot of heads towards its prospects that lie in its design and results.
