Original Prusa i3 MK2S

Features

Before starting to talk about the features of the 3D Printer, it is important to know that the machine is available in different formats. One can but a kit or can get the pre-assembled format.

Moreover, one can also print the entire machine using another 3D printer. The designs for the different parts are available on the company’s website.

Although it isn’t predictable if the designing of the entire machine from scratch would be any cheaper, it definitely would be an amazing experience.

Talking about the features, there are many notable ones which would leave you awestruck. Getting so much for such a little price is a true value for the money you pay.

E3 V6 Hotend: The company has ensured to use the best in class parts to provide the highest reliability. TO start with, the printer uses an E3D hotend.

Those who are not aware of the benefits of the nozzle, it is an all-metal hot end capable of handling higher temperature. The Original Prusa i3 MK3S make use of the E3 V6 hot end.

Bondtech Drive Gears: To make the duo even stronger, The ED3 hot-end is complimented by upgraded Bondtech drive gears. The drive gears help in enhancing the steady flow of filament to the hot ends.

These grip assists the flow by holding the filament from either side, hence, reducing slip and at the same time, increasing the push force. This also allows the printer to work great with the most notorious of the filaments.

Automatic Loading of Filament: A lot of users have described how difficult it could be to load the filament sometimes and with few printer designs.

However, with automatic filament feeder utilized in Original Prusa i3 MK2S, all you need to do is pop the filament into the extruder.

The rest would be taken care of by the sensor that detects the material and pulls it into the machine. After the filament is loaded, you just need to make the selection for the filament type.

Upgraded Build Plate: The removal of models after they are completed isn’t very easily most of the time. With MK2S, however, it is simple and effortless.

Unlike the old version that used a glass plate along with the bull clips to hold the plate in place, MK2S utilizes magnetic HeatBed along with a spring steel sheet, coated with an alloy PEI.

Using this plate, the printer tackles the post-processing in a very simple manner. The MK3S is shipped with a smooth PEI sheet.

However, you can also choose the textured powder-coated version. This is only available on request for some extra bucks to further increase the adhesion.

Sturdy Aluminium Extrusion Frame: The 3D Printer is sturdy and uses aluminum extrusion that was introduced in the MK3. This aluminum extrusion is utilized for the Y-axis as well as for the high-quality lead screws.

Quiet Operation: You would be amazed to see how quite this printer works. In the stealth mode, the printer won’t make noise and let you work in silence.

To do so, Prusa makes use of the highest quality stepper motor and combines them with Trinamic2130 drivers. For cooling, it uses Noctua fans. Hence, one can print without any disturbance when using the printer in the stealth mode.

Power Loss Recovery: This is a very important feature that helps the user save themselves from print failures. If the power is lost in between the print, the model won’t be wasted.

The printer would save the progress and would resume from where it was left after the power comes back. The MK3S helps to recover completely after the power loss. So, even if you are out of power for longer, the print would always start from where it was left.

P.I.N.D.A. 2 probe: This is also one of the most important features of the 3D printer. This means that the machine boasts two thermistors.

Of which, one is used for checking the suitable temperature of the electronics. On the other hand, the other P.I.N.D.A. 2 probe is utilized for adjusting in case of any temperature drift that may occur at the print level.

This helps in making sure that the adhesion of the first layer is always optimum.

Open Frame: The printer has an open frame. Hence, the printer is open from all sides. This helps in increasing the visibility of the prints. However, may not be safe when working at home with children around.

All these features are very helpful in making this printer a great choice for professionals. The 3D Printer ensures the ease of use as well as ensures high-quality prints for best results.
