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.

I have been using this for a little over a month now, and I can't say enough great stuff about this printer! I have now successfully printed more things in a little over a month than I had been able to print on my old Ender 5 Pro in 5 years. I have gone through over 5 kg of filament in a month, printing a dragon (with the picture I attached. The detail is absolutely fantastic with even the base settings (I am now printing some stuff with the .1 mm detail settings, and it's even better than the base!). I also printed a Five Nights at Freddy's mask for my daughter that used about 2.3 kg of filament, and have also been printing things from Scan The World that are 3D scans of artifacts from different cultures around the world (such as a Celtic mile marker, a relief of Saint George defeating a dragon from the San Gorgio Cathedral in Italy, statues from Aztec and Mayan cultures, ancient Egyptian reliefs, among others). Yes, the price on this is a bit high for being a "bed slinger", but I am EXTREMELY happy I went with this over another proprietary, planned obsolescence Chinese brand (like Bambu or Ender). Once the upgrade to the MK4S is more widely available, I will definitely be upgrading! Original review: I have been 3D printing for several years now, and have a lot of successes with Resin printing. Previous to purchasing the MK4, I have worked with the Ender 5 Pro that I have owned for a couple years now. Until I got the MK4, FDM printing was excruciating. The Ender 5 is the printer you want if 3D printing isn't your primary passion, but tinkering is. Me? I like to tinker, but I don't want to have to tinker for 6 hours every time I want to try to print, then have a failure halfway into a print, just to then have to tinker for another 6 hours, have to buy more components to replace stuff that went bad or then have to clean the nozzle because it didn't do the layers right, or a myriad of other things that it had go wrong to keep me from actually *printing*. I've read a lot of things online about the MK4 (and MK4S) and the consensus seems to be that while you still have to do some adjustments and tweaks from time to time, it just runs. I didn't get the pre-assembled printer, I got the kit, so I knew I'd have some assembly and testing to do. So, how was assembly and testing? Well, I ran into a few small hiccups. First, I didn't have the Y belt tightened quite right, so the Y calibration step failed. Few tweaks and it succeeded. Then, I got it to print the Prusa keychain, and then decided to do an actual print. Print shifted on the X axis, so failed. Looked it up, and realized the X axis belt wasn't tight enough. Tightened it, and then the X axis calibration failed and I couldn't figure out what was wrong. Went to the Prusa Discord channel and explained what I did, and within 2 hours had someone point me in the right direction, and I then was able to do my first actual print! And holy moley was it a nice print! Even when the Ender 5 would actually print, it wasn't spectacular in any way, but this actually impressed me massively! I haven't done a second print yet (about to load one up when I'm done typing this), but I am already 1000x happier with the MK4 than I ever was with the Ender 5. There is one question that I'm fairly sure that is being thought by those that know to ask it: why didn't I get the MK4S? Well, that was initially the plan, and I tried, but there was a backup of orders for it, and I had no idea when I'd even get it. So, I decided I would get the Mk4, and if I like it enough, when the upgrade kit becomes more readily available for the MK4S I would get it. If the MK4S is an improvement over this, then I will definitely get it when I can!

As a design engineer, I use 3D printers as part of my job. I’ve used every type of 3D technology there is. The kit instructions are good, pictures could be clearer. Took about 3 days to assemble. The frame is aluminum, feels sturdy/stable. Started up without any issues or trouble shooting. The removable print bed (sheet) is awesome. Prints stick without the need for glue or tape. Bend the bed and the print pops right off. These are both huge issues with most low-end printers. Print quality is professional quality, smooth, no stringing, no goobers. Print accuracy is excellent. I did a 1” test cube and the features measured within .004”. Many printers I’ve used undersize holes by about .025”. These are spot on! The user interface is easy to use and shows you a picture of what you are going to print. The printer is fast (twice the speed of my old printer). The printer even has a filament sensor which stops printing when you run out. That allows you to load more filament and continue printing instead of having to scrap the print job. This is a must have if you are doing large prints. The Prusa slicer software is easy to use and is similar to most slicers.

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 pretty awesome little printer. It took me 3 days working a couple hours each night. I accidentally mixed the x and y connections on the mother board so it wouldn't calibrate when I first fired it up. After reviewing the books that came with it and realizing that the x axis is the left right of the machine calibrated with no problems. Getting the prusaconnect and prusa link took a little to get connected but works like a dream after slowing down. The instructions were thorough and well written. I wanted to verify some pieces that came with it were the actual pieces I was supposed to use so I used the online chat. It took a few minutes of waiting before I got some help but once I did it was quick. Prusa slicer is pretty straight forward and has great features to get started and has different levels of set up from beginner to expert that allows you to customize it as you learn the program and become more familiar with 3d printing. I would by this machine again and I had fun putting it together but it does take time and patience.

When they say “kit”, they mean it. If you’re not ready to spend 20+ hours putting it together, keep looking. That’s the first 1 star. But, the instructions are fantastic, the parts are all present (don’t misplace any of the little bags!), and the thing is solid and beautiful when assembled. That’s a 5 star. But, it didn’t work. The head thermister did not register that the head was heating (but it was). PRUSA support (in Europe) was great, helped me diagnose the problem and parts were to me in a few days. That’s another 5. It still didn’t fix the problem. This time support wanted me to go through Amazon, but finally agreed to sent more parts — which never showed up. The final 1 star. Oh, well. It’s going back. $1000 for a solution in search of a problem didn’t work.

The gummies are very important part of the install. Don't eat them without following the directions! Very solid printer. Assemble, calibrate and buy tons of filament and enjoy. Very stable, reliable printer. Could buy a faster competitor, but this thing is rock solid. Also, the manufacture lets you print your plastic parts, even provides the .STL files to print them yourself. Doubt I will ever use them, but its a nice safeguard to have a box of breakable parts in a box in case it every happens. Expensive, but well worth it. Get this one, you won't be disapointed at all.
