The Original Prusa i3 MK3S+ is the original Cartesian-style FDM 3D printer kit made by Josef Prusa. According to All3DP.com, the Original Prusa i3 MK3/S is the “Best 3D printer of 2019”. It is a redesigned version of the i3 MK2 that offers a variety of innovative features such as an enhanced extruder, upgraded filament sensor, resume printing function, and many advantageous cumulative upgrades. This machine stands as one of the most reliable and user-friendly ones, providing a steep but enjoyable learning curve during its assembly. 

The printer features a removable heated bed with replaceable steel sheets, reworked Y-axis for increased rigidity, and an optimized frame. It also offers an easy-to-use dual-color printing option, brand-new thermistors for perfectly accurate first layer, and an all-metal hotend. This stylish device has a print area of ​​250 x 210 x 210 mm and works with a wide range of materials. 

The MK3S+ is an ideal device for entry-level users, tinkerers, and more experienced makers. It is widely used by hobbyists and small businesses to design original household items, souvenirs, tabletop miniatures, prototypes, souvenirs, props, cosplay accessories, and much more.

Print Quality

The Prusa i3 MK3S+ is an FDM 3D printer that can print layers at 50 microns. This way, you can produce parts with smooth exterior surfaces. Have a look at this model of Thanos. The model is incredibly smooth and rich in detail even for this type of a 3D printer.

The Prusa i3 MK3S+ has a 0.4 mm nozzle, which provides higher speed and better quality of printing. 

The print head runs on rods with linear bearings providing an enjoyable experience of 3D printing and making it more simple and effective.

By assembling the printer, you will get a solid knowledge of the 3D printing process. This learning experience will come in handy when replacing a part or upgrading the device.



Prusa i3 MK3S+ is suitable for working with a wide range of materials such as PLA, PET, NYLON, ASA, and a variety of other filaments.

The device is equipped with an extra-silent fan for printing with PLA-type materials and greatly contributes to dealing with problems such as stringing and warping.

To ensure high reproducibility, we recommend installing an enclosed print chamber. This way, the print quality won't be affected by temperature fluctuations as a result of drafts and other factors.

The Prusa i3 MK3S+ prints with 1.75 mm filament, providing you with a wide choice of materials.
