Which 3D printer surprised you the most after long-term use ?

It wasn't actually surprising but after thousands of hours on both machines, I just have to say I'm really happy with Prusas. I have MK4 at work and MK4S at home. I'm not the type of person who has a screwdriver in hand all the time, quite the opposite but I took upgrading MK4 to MK4S at home as a challenge. Got myself the kit and felt like a real mechanic for a few hours, lol. The surprise part is how easy it was. You don't need any experience with technical things at all. I read a comparison to Lego and it's actually quite fitting – you get a manual so you don't mess it up and then you just go step by step until it's finished. And then there is their support. As I said, I'm not the technical type at all so I wasn't really surprised it failed some heating test after the upgrade. I contacted the support via chat (on Saturday night!), they navigated me how to use the multimeter to check where is the problem and sent me the part I accidentally damaged immediately. Maybe it's not that shocking but it is for me, I haven't experienced such a positive interaction with customer support in my life.

WATCH This Before Upgrading to the PRUSA MK4S

The MK4S is an upgrade kit for the MK4, featuring stronger PCCF parts, a new LCD cover, and a larger cooling fan. While the upgrade process is straightforward, its performance improvements over the MK4 are minimal in most print quality tests and print times.

Broken Printer 😔

I had my fan shroud break on my MK4S from a blob (same kinda thing) and I just super glued it temporarily until the next time I ordered off the Prusa store where I just threw one in my basket (I always miss the PC-CF drops so that was quicker!)

Beginner 3d printer

As you didn't mention the budget, I would strongly recommend Prusa. MK4S is lovely, easy to use for a complete beginner, you get a very handy manual with it, Prusa slicer is very intuitive and the quality of printing is awesome. I didn't have any problem with mine so far but their support is available 24/7 in 7 languages, so if there would be any, I expect it to be solved super quick.
