It is no wonder after reading the following article why the Prusa I3 MK2 3D printers are one of the most popular and most trusted 3D printers ont he market. See at least 7 reasons or new features that make Josef Prusa’s design highly stable and extremely popular:

Prusa I3 MK2 3D Printer


Josef Prusa’s designs have always been trustworthy. He has a talent for scouring the body of work out there in the RepRap community, finding the most valuable innovations, and then blending them together along with some innovations of his own into something greater than the sum of its parts. So, it’s not hard to say, that once a feature shows up in one of his printers, it is the direction that printers are going. With the latest version of the often imitated Prusa i3 design, we can see what’s next.

The printers from Prusa research are my recommendation for anyone getting started in 3D printing who wishes to understand the magic box on their desk, humming away into the night. The Wanhao duplicator is okay, but it’s a cost optimized version of the work done by Prusa, E3D, Ultimachine, and others. You’ll only learn when it breaks, and it will break. Prusa puts top of the line parts into every printer, the design is accessible, and the documentation is the best out there. It’s the Old Heathkit quality of 3D printing.

As Prusa tells us in the video interview below (we caught up with him at the Microsoft booth at Maker Faire — a RepRap at the Microsoft booth!), The MK2 is packed with new features.

Auto Bed Leveling and Its Many Benefits

Le glass et mort.
Le verre est mort. Prusa recently posted a trashcan full of borosilicate glass plates on his twitter. 

There’s been a big push for auto bed leveling in the industry. It’s my absolute favorite upgrade for my printer. In my mind, it transformed the printer. I didn’t realize that being forced to level the bed on my printer was keeping me from using it until I did away with the chore.

Starting with servo motors moving limit switches into place, and ending with non-contact inductance sensors, the reprap community has been moving towards auto bed leveling for a while. At MRRF this year SeeMeCNC was showing off their tiny Eris delta printer which uses accelerometers under the build plate to accomplish this task. The MK2 uses another trick, with a non-contact inductance sensor for its own auto bed leveling.

before the MK2. A cold-corner compensating heated bed is a bed that has different trace densities at different parts of the board. This allows the heated build platform to put more energy into typically colder parts of the bed; which results in a more evenly heated area.
