Product Description

The Original Prusa i3 MK3S+ is the latest version of our award-winning 3D printers. We have upgraded the MK3S with a new SuperPINDA probe for improved first layer calibration, added high-quality Misumi bearings and various useful design tweaks to make the printer easier to assemble and maintain. The MK3S+ includes all the proven features of the previous models, including the heatbed with removable PEI spring steel print sheets, automatic Mesh Bed Leveling, filament sensor, power loss recovery (power panic) and safety features. And it is still as silent as ever.

    Nice Printer, Needs simplified manual (shorter!), Helpful hints for assembly (things to look for)
    So, the product itself is overall good. I chose to assemble for two reasons: Save money, Get familiar with my new 3D Printer.The manual is ridiculous! It needs A LOT shorter with less pictures. There is NO time to play the gummy bear game. The pictures need to be larger, so you don't have to go online to zoom in. I've been a machinist for over 30 years and I am very mechanically inclined. When I got to the bearings, which do not seem to be of the highest quality, they were fairly quiet and smooth while sliding them over the shafts. The problem is once you tighten things up and install the bed, it is not likely to be smooth any more. I actually assembled the printer on a precision granite plate and used a height gauge to ensure all the rails were within .002" of each other and used calipers to make sure the rails were the same distance apart... and it still did not slide smoothly. My solution was to barely tighten the bearing clamps just enough to hold them in place without being loose yet give them a little 'wiggle' room. This helped a lot.It would also be nice to have a simple (short!) single page of steps to help you quickly achieve successful printing. I ended up doing trial and error and watching some videos online. A beginners video of this exact model printer using the exact included filament would be nice to have walking you through your first test prints that are included on the SD card. There are a lot of videos out there but they are either different models, using different filament, or both... Kind of hard to troubleshoot when the conditions are different.From further research after I got the printer, The printer itself seems to have "old" designs and the programmers have been very successful in fixing a lot of the previous problems via software instead of hardware changes. I like the printer but my next one will likely be a different brand unless Prusa releases a brand-new revised printer with less 3D printed parts and a way to assemble more quickly and easier while retaining tighter tolerances between the bed, bearings, and rails. This would be worth paying more to me.My first few prints were good, however, when I cleaned with 99% alcohol very carefully, the prints started lifting. I ended up picking up some acetone and so far, it seems to be holding better. I'll likely be getting a non-smooth plate to put on while printing to help as well as an option other than the smooth one included.I have achieved some nice prints and I am sure I'll get a lot of quality use out of this printer for a long time. I don't regret my purchase as the final results with a lot of hard work assembling it made it function quite well and quietly.

    La impresora se ensambla muy fácilmente, aunque si requiere algo de tiempo. El tiempo de envío fue el especificado.
    Lo único es que la descripción del producto dice que incluye 1kg de filamento y no venía en la caja. Por todo lo demás, la recomiendo ampliamente.

    3Dプリンター初心者です。いろんな情報を入手し、Prusa i3 MK3S+キットを購入しました。
    完成版とキットとどちらを購入するか迷いましたが、3Dプリンター構造を理解するにはキットにして良かったと思います。
    完成まで3日ぐらいかかりました。詳しい写真入りの日本語組み立てガイドが入っていて初心者でも大丈夫です。
    ただ、付属の六角レンチで回すには時間がかかります。私はベッセル電動ドライバー(2.5ビット)を使用しました。

    苦労した点は、ナットが3Dプリント部品に奥まで入らないので、ガイドには「ネジ引き技術」の説明がありますが、ネジをしめすぎて部品を破損し、ナットが空回りしてしまいました。
    こつとしては、ナットを部品にはめ込み、反対側からネジを差し込み、少し回しては戻し、少し回しては戻しゆっくりナットを部品にはめ込んでいくことが重要です。
    一気にしめ込むと、ネジが外せなくなるので慎重にネジを回す必要があります。

    部品を破損して前に進むことが出来なくなりましたが、サポート窓口にメールを送ると、すぐにメール返信があり、着払いの送料のみで部品を無料で送ってくれました。本当に神対応です。
    しかも送ってもらった部品のほうが元の部品より奇麗でした。

    完成してからのセルフテストも上手くいきませんでした。X軸のエラーが出てしまい、覚悟を決め、せっかくまとめたケーブ束の結束バンドを切り、X軸のベルトを外して再度ベルトを微調整すると上手くセルフテストをクリアできました。

    セルフテストが済むと、次はファーストレイヤーキャブレーションの設定がよく分からなく、実際キットが完成してからサンプルデータを印刷するまで1ヶ月程かかりました。

    3Dプリンターは、焦らずゆっくり諦めずにやるのが重要だと思います。
    ゆっくり経験を積んで頑張りましょう!

    なお、電源は3Pプラグの差し込み可能なマルチタップで普通に使用できました。

    FUSION 360も並行して勉強中です。自分で設計した物をたくさん印刷したいです。

    El kit para armar resulta ser una muy buena experiencia en el manual viene bien explicado. Una vez superado el reto de ensamblarla, la impresora es una maravilla tanto por software como por hardware, es muy amigable la manipulación.
    Una impresora recomendable por precio y calidad.
