MK4S 3D Printer kit, Removable Sheets, Beginner-Friendly 3D Printer DYI Kit, Fun to Assemble, Automatic Calibration, Filament Sample Included, Print Size 9.84 x 8.3 x 8.6 in

Works great and buying this printer as a kit did save some money but note that I found it a challenging assembly. I have built quite a few computers but this was more difficult. At the end I wondered whether the saving was worth the frustration. Getting the tension right on drive belts takes much more fussing around than just screwing in a board or a drive. In several places some assembly required awkward reaching around the printer. The step by step directions were good and the comments inserted into the guide by other users were sometimes essential - when the wording in the online guide was not as clear as it could be. Clever idea to include such comments. I added my own when I thought I could contribute. I also used their online 24/7 chat to get help a couple of times when I could not figure out why I could not get the printer to pass a calibration test. It turned out that i had not noticed that one of bearings had slipped out of position. Only thing negative I can think of is that the power cord did not fit very well and could become loose - which would turn the printer off! Fortunately, I had a compatible cord from an old computer and it fits perfectly. I guess I could have tried filing their plug down so it would fit better but easier to just swap cables. I have now printed a number of things starting with the easy to use PLA filament. My first try with the TPU (FLEX) filament was not so good but they do warn you of possible difficulties with that kind of filament.

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!

i3 mark3sから引き続き購入しました。 まず、組み立て説明書の添付が無い。そういう仕様なのか入れ忘れなのかわからない。 前回mark3sは英語版の説明書だった。説明書が中国語を英語に翻訳したような感じだったので、 日本語版をネットで探しダウンロ－ドした。日本語もおかしかった。ネジをネジするみたいな表記だった。 今回は、日本語版を最初からネットで探して組んだ。 寸法精度が完璧で、１００分の１単位まで合わせてある様で、設計が素晴らしかった。 １０時間くらいかかったけど、あとちょっとで完成ってとこで、ネジ袋が不足してた… 特殊形状なので、代用ネジが使えず困りました。 Amazonに問い合わせたところ、ネジだけ送る事が出来ないので返品か交換と言われたが、１０時間かけて組んだものを 返品する気も無いし、そもそも返品出来ない。 仕方ないのでPRUSAから補修部品で注文しようとしたが… そもそも海外製なので、輸入になる。 輸送コストが高く１か月くらいかかりそうなので、現実的では無い。 知ってるネジ専門店に問い合わせしたところ、仕入れられそうなのでそちらでネジだけ注文しました。 キチンと正しいものが来るといいけど…←（今ここ） 海外製ですが、設計は完璧で印刷クオリティは業者さんに頼んだ物に負けないクオリティで気に入ってますが… 他の方のレビュ－にある通り、足りないものが有ったりするみたいです。 そこは外人従業員の質の問題だと思いますので仕方ない。 ３Dプリンタ－構成樹脂パ－ツの破損時は、プリントできるデータが公開されてるのは有難いですね！ 補修部品などの供給がサクッと出来る様になれば良いんですが…

完璧な体験でした。迷ってる方はすぐに買いましょう。 MK4SやMMUのアップグレードキットがAmazonに並ばないのが残念。

Brilliant works great i got the kit version built it over 3 days on and off if you not good at reading manuals there is a step by step guild utube videos you can watch and guides you through it highly recommend this 3d printer thank you prusa

Il kit è arrivato in perfette condizioni, montaggio senza alcun problema, e prima stampa uscita perfetta. Ma è una Prusa, non avevo dubbi.

Le kit est globalement bien conçu, les instructions claires, mais ça reste beaucoup trop cher pour ce que c'est. Les plus de la mk4s : - Rapide - Fiable - Précise Les moins : - Beaucoup trop chère - Conception douteuse de certaines parties (système de tension de la courroie de l'axe Y) - Peu d'innovations par rapport aux modèles d'il y a 7-8 ans : il s'agit d'une plate-forme arrivée au bout de son cycle de vie (vs les nouveaux modèles de cette marque) Accessoirement, lors de l'achat une date de livraison été indiquée mais finalement on a essayé de me livrer la veille, ce qui n'était pas possible pour moi.
