Nice printer overall for hobby and semi-pro prints. Great new firmware with multiple bed support and great slicer

Best printers I ever had!
The Prusa i3 Mk3 is a top of the line printer. The print quality is top notch as well as the reliability. The only draw back is its cost compared to other printers.
Even better than the MK3.

Fantastic workhorse fdm printer. I highly recommend it

One of the best printers I have used.

As of Mid 2019 this is the best printer on the market for a hobbyist. It's a little more expensive than some others out there but it is incredibly reliable and is backed with quality support and a huge community of helpful individuals. You cannot go wrong.
The best choice in the sub 1k.

The best choice.
This is a reliable 'set and forget' 3D Printer. Print quality is very high and machine reliability and ease of use are second to none. I'll definitely be procuring more as the work demands.

Very Good printer
Best printer I have ever owned.
Una delle stampanti migliori sul commercio
Great and reliable machine! No issues at all.

Very reliable and easy to operate
Nice printer. Just plug and start doing it, no complications, reliable and worth every buck you spend on it. On a good year using this website it will pay itself alone if you deliver at least one print per week.

The Prusa MK3 is just the most relialable 3D printer I has ever seen and used! Print qualities are just awesome. It's a very easy printer to use, capable of handling most type of materials so far: Abs, Pla, Pet, Pc, Flex... It can surely compeates with other most expensive printers on the market such as Ultimaker or Raise 3d.

Best in its class

Great printer, exceptional quality. I would pick it over any other printer
Fantastic printer that is solid and reliable with great support.

It just works.

Works for any basic parts very well. Using the default Slic3r software, the support settings are lacking. I find that the surfaces are quite rough even after lots of testing, so I often opt to use another software, or to sand the parts in post-processing.
