When it comes to 3d printing I'm at most a hobbyist. This Prusa MK4 is my first 3d printing experience of any kind, and the last few months have been a learning curve. I don't expect to add much to the slew of enthusiasts who will critically analyze the performance characteristics of the printer, so these remarks will be limited to only what I think might be helpful for someone of a similar perspective. Kit vs. assembled? - Kit all the way! - This is more than just "some assembly required". Every wire, every screw, every reducible part, must be put together. It took hours spread across three or four sessions to get it fully together. - If I hadn't put it together myself, I would have far less understanding of how it works. If anything ever needs to be repaired, or if I ever want to upgrade or accessorize, having a good foundational knowledge from assembly will be helpful. - As a novice, seeing the parts, many of which are 3d printed, and how they fit together gave me insights that are helpful in designing my own 3d models. Thoughts on the kit: - It is impressively well coordinated and documented. Hundreds of parts, and every one was present in the right bag, with the right quantity. - It takes attention to detail. All the stuff is there, but it's up to you to make sure it ends up square, appropriately tight, everything completed. The printer itself: - Works well once assembled. Easy to learn. No issues with leveling. - A bit noisy if you're sharing space with it, but not obnoxiously so. - I've successfully printed a few dozen things in PLA, PLA+, and PETG. I prioritize quality over speed. I've been happy with the results in most cases. The software: - The main program you'll be using is called "PrusaSlicer". - PrusaSlicer has a fairly steep learning curve, though many of the more complex configurations are hidden behind mode settings "Beginner", "Normal", and "Expert". You'll want to dig into the advanced modes, because much of what's needed to get good quality prints, like seam settings, painted supports, and so on, are only available in the more advance modes. - The help links don't always point to the right webpage, but it's usually possible to find what you're looking for with a little searching. Thoughts on 3D printing in retrospect: - Expect limitations. I very quickly discovered that 3D printing is not precisely the ability to easily make plastic parts and shapes. You're dipping your toe into a space that has spawned entire industries and branches of science. It doesn't "just work". - 3D printing one method (out of many) of making plastic shapes, and a method that comes with significant limitations. It's not food safe. It's not watertight. It's fairly heat sensitive. As a rule, everything you print will be solid colors. - If you do end up wanting to print something really specific and can't find a pre-existing model, you'll need to learn 3D modeling software, and that is its own whole can of worms. - Check out Tinkercad, move on to Autodesk Fusion. Take tutorials. Strategies: - Dive in and learn stuff. You will need Expert mode. You will need to learn 3D modeling. - It's not all about the plastic. Filament will only get you so far. Eventually you need to think about screws and anchors, motors, bearings, magnets, and epoxy. Your printer isn't made only from plastic parts, and if you want to do serious and interesting things with it, you'll need to think bigger as well. - The world doesn't need more cutesy plastic animals and phone stands. It needs more people capable of genuine creativity. In the end, I'm glad I bought this Prusa MK4. I've accomplished some interesting things with it. The quality is excellent. More important is the philosophy of something you build yourself from different types of components, expecting that it can be repaired and modified. This sort of thinking is underappreciated in modern culture.

Great to build and use for kids, can be assembled in a day with a lot of fun. Works fine right after assembling. Different brands of PETG and PLA filament from Prusa, Bambu Lab, and Esun print well even with generic profiles, while extrusion multiplier and bed temperature tuning according to ambient humidity and temperature are beneficial for accuracy to print miniatures. Very durable build and can be moved by the top of the frame. Surprisingly quiet even for a live room. Part cooling is fantastic while still very silent. Prusa Slicer integration (i.e. Prusa Connect) and iOS/Android mobile app with cloud slicer (i.e. EasyPrint) just work too. And it actually costs about the same as a cheap Chinese 3D printer like the Ender 2 v2 with a replaced extruder, powerful full-metal hotend, linear rails, quality Z axes, a custom cooling system, RPI Zero W2 with Klipper, etc.

When I bought this I didn't realize it was a kit and that I would be basically building the entire thing myself. It took me almost a week to build it by working on assembling it a few hours each night after I got home from work. When I finally booted it up it got hung up on a wiring self test so I contacted Prusa's help chat line and the person I was talking to diagnosed the issue in under 30 seconds. I swapped where two wires were plugged into the circuit board for the extruder and I was ready for action. This is my first 3D printer and I went with this model because it has a number of preset settings and automation that make it easier for a first timer to get into the hobby. The good thing about Prusa is that they have good support for their printers and provide updates for their legacy printers making them upgradeable over time to increase functionality and extend their capabilities. The build quality of the printer seems pretty good and Prusa makes a lot of the plastic parts on this printer from other 3D printers and also offers files online for free if you ever need to print your own replacement. The user interface is pretty good with a full color display that has easy to navigate menus and good feedback while something is printing. I haven't had many issues with failed prints but when I did it was obvious that there was either a filament issue, a part/model design issue, or something wrong with the way I set up the print in the free slicing software. I've printed probably a half dozen brands of filament so far in many different colors and had no issues with extruding or filament jams. If you have a bit of extra money to lay down (there are other printers available for less out there) you won't be disappointed in this printer. Prusa makes solid printers that have very long life span and I expect this printer to live up to the name. I've not had to do any maintenance on this printer except for cleaning off the outside of the extruder hot end once.

This is a great product. I would suggest to be very patient and carefully read assembly instructions if you get the kit. The belt tuning (tension) app didn't work for me, but it's not necessary.
