Prusa i3 MK2S 3D Printer

Assembled Prusa i3 MK2S

I spent a lot of time and energy researching 3D printers before finally buying one, and even then I am not real happy with the first one I bought, but that will be another post. This one is about the second printer I bought and love, the Prusa i3 MK2S Kit.

The Prusa i3 MK2 is a very popular and highly rated printer, Make Magazine gave it their Outstanding Open Source, Best Value, and Best Overall awards in 2017. Thomas Sanladerer says “The Original Josef Prusa i3 MK2: It doesn’t get any better than this!

You may have already done some reasearch and found that it takes up to 2 months to get this Prusa kit ship shipped to the states, I ordered mine on February 13 and it did not ship from the Czech Republic until March 31st and I received it a few days after that.

The total I paid for the kit with shipping came to $781.26. In the world of good 3D printers with auto bed leveling, a heated build plate, 8 inch by 8 inch by 8 inch (it’s actually bigger than that) build area, and quality components like the E3D V6 hot end, is an amazing price.

I could have bought it assembled for $200.00 more, but I believe you should have the experience of building from a kit as you WILL be taking it apart to maintain it if you are going to be serious about 3D printing.

Putting the printer together was not that hard, Prusa provides wonderfully detailed directions online in a format where you can ask questions and get clarification quickly. Many times someone at Prusa will even update the instructions based on feedback within a couple days of a comment being made. I used an iPad to view and follow the instructions, it worked great.

There are also many videos on YouTube, some as long as 12 hours, with people building their Prusa i3 MK2 kits. Also there are many video reviews, troubleshooting help, and timelapses of prints in progress.

After 6 weeks or so of printing about 18 hours a day, something went wrong with my printer. I am still not sure exactly what went wrong, because I bent the heat break tube while trying to fix it. I ordered a new tube, nozzle, and boden tube from the MatterHackers website. I then proceeded to make some mistakes when re-assembling the E3D hot end which triggered a chat session with Shane at Prus who patiently helped me troubleshoot the issue.

I led him down multiple wrong paths, I kept thinking it was an issue with the extruder motor, but eventually we figured out the issue was the filament cooling where it shouldn’t be. I spent some time with the E3D V6 Assembly instructions, figured out what I was doing wrong, took it all apart for the fourth or fifth time, and carefully assembled it following the E3D instructions to the letter. Then BANG! I was back in business.

If you are looking to get into 3D printing and want a printer that will last a long time, is easy to fix and maintain, will print almost any filament, and are willing to spend around $800.00 to get started, I recommend the Prusa i3 MK2S kit over anything else on the market.

P.S.
The MonoPrice 3D Printers are getting great reviews and prices cannot be beat. I have been tempted by them, but I think I would save up and get another Prusa with all of its features instead.
