Original i3 Prusa Mk3s: A perfect 3D printer in your way

The Original i3 Prusa Mk3s is a flagship 3D printer that is the descendant of the Prusa Mk printer series initiated in 2012 by Prusa Research. It was founded by Joseph Prusa who is one of the key figures in the core RepRap developers. It has consistently improved its efficiency since then and has marked its boundary in the printing industry. It is an open easy-to-use printer and has the feature of removable prints. With upgrading options, it is one of the expert’s-built quality products. I have used several 3D printers, but this Original Prusa i3 MK3S gives you a wonderful experience with its distinct wiring routing. Although it may seem that the Prusa i3 Mk3S is like previous products from the MK series, under scrutiny you will see the major difference between the two.

Design and built Quality of the Original Prusa i3 Mk3S

3D printers are not on the criteria of being aesthetically pleasing, yet some manufacturers like the Cel-Robox and MakerBot are involving product designers in their recent products to make them aesthetically appealing. A major part of this shift can be the 3D community which likes to deal with cool design products. Prusa has retained the design of its original products. For them, the appearance will mask the impact of the overall product if its working efficiency is not up to mark.

The Original Prusa i3 MK3S along with its previous generation has an open design and a normal look. If you place it in your design studio or at your workplace, then it won’t look bad. Prusa greatly believes in print quality, so if you are going for an aesthetically pleasing printer, then this printer may not be the one for you, but remember it is one of the best printers out there because of its print quality.

The Original Prusa i3 MK3S is available either as a kit or in fully assembled form. On ordering it will be shipped from the Czech Republic. The printer is laced with red and black color and has a dimension of 15 by 19.7 by 22inches. It has a larger print volume and when I printed my project documents, it enhanced their color to a greater extent as compared to other 3D printers. The Original Prusa i3 MK3S is a square arch product that contains a metal dowel. All in all, the design is sleek and allows the users to experience good-quality printing at an amazing price.

Setup and performance of the Original Prusa i3 MKS3

The setup is quite amazing in a fully assembled form. This means that you just have to attach the spool holder. You need to lift it out of the box, and it is not small in size, so it will require your attention. Installing it is exceptionally easy which means that when you power it on and press feed on, then you need to dip the end of the filament into the hole of the extruder and select your desired filament type. This will make the molten filament appear through the nozzle. When it comes to charging the filament, you can eject the small LCD with the control board. This means that you can pop the filament out and install it at any time.

The quality of the prints is finished. I checked for firmware updates and used different slicers that have simplified 3D, Cura 4.0, and PrusaSlicer. PrusaSlicer is straightforward and has an STL file which is ready for printing and selecting the quality options. Connectivity can be done by using a USB connection. There are two Type-B ports along with a supported SD Card interference as well. One should remember that an open-frame printer can cause many hazardous damages, so one should keep away from such kinds of incidents.

PrusaSlicer Software in the Original Prusa i3 MK3S

The Original Prusa i3 MK3S uses a PrusaSlicer 2.2 software which is based on the Slic3r program and makes an object into a 3D image stored in formats such as STL, OBJ, AMF, or 3MF. It converts these products into G-code files and allows the encoded information to make a 3D image of the product. It is an alternative to Cura, which is the basic software of many other 3D printers. They both perform the same function and have a commonality in loading images, editing, resolution setting, filament type, and supporting images.

For me, the PrusaSlicer worked wonders because I had already installed it because of the Prusa Mini, so I added the program MK3S, and it worked so well that I am not going to change to any other software. It codifies the file into multiple thin layers allowing it to be printed as the object builds up. It can be done in a simple, advanced, or expert level interface and everything is just a piece of slice for avid users.
