Upgraded Ender 3 v2 Ender 3 CR-10 All Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Creality Ender 3 Pro/Ender 5/ CR-10 Series 3D Printer

Like a lot of others, my Voxelab Aquila's stock plastic extruder arm cracked not long after I got my printer. I printed a replacement arm, and that actually got me by for about 4 months, but that arm started to wear out and was causing unreliable extrusion too. I didn't really feel like I needed to upgrade to a dual gear, or even a direct drive set up for my PLA and PETG printing, so I started looking into the aluminum stock replacements. I've heard these can have issues of their own; the spring can be too stiff, bad hardware, no instructions, and the pivot spacer can be too short which keeps the arm from moving. I'm happy to report, this kit has none of those problems. The stock spring is working fine, parts are all well made and fit great, no problems with the hardware and fittings. Instructions consist of an exploded view drawing with the parts labeled, which was enough for me. If you really run into trouble, there are a bunch of videos out there, or just look at your stock extruder, it goes together the same way. I'd suggest assembling the roller to the arm first, then putting everything else together with the spring being last. So all in all, this is a great kit. I'm surprised a kit of machined and anodized parts like this can be sold for such a low price to be honest. I feel like maybe aside from the brass extruder gear, the rest of these parts should last the life of the printer. If you are shopping for one of these, and seeing about 30 different versions that look the same, just get this one and be done with it.

Good product Works perfectly Sturdy construction

Fixed my feeding issues on Ender 3 v2, I could tell I had issues when prints failed and had "dust" up around this extruder. Thought it was a clogged nozzle but kept happening after checking/cleaning nozzle. Finally replaced old one with this and next print was perfect!

I was looking for some knob handles for my poi, and unsure of the size, shape and weight, and realized it would $15 to buy most pairs I was looking at. They were all 3d printed TPU and I normally just do things myself but Ive got a fairly stock Ender 3 (other than the bullseye cooler) and been told it couldn't do TPU because of the Bowden. Well instead of spending $30 on a couple pairs of handles I decided I'd spend the same on this and a roll of TPU and figure it out anyway. Status quo be damned! I got the TPU first and tried to print it, but got nowhere. There was a gap between the extruder gear and the intake of the Bowden tube and the filament would just push out there and never actually be forced into the hot end. I couldn't even print a purge line. I got this today and installed it. Its pretty simple and similar the original so taking that one out should tell you how to put this in. I just printed my first TPU item and it came out flawless (although at 20mm/s but I decided to start conservative) Now that that works I plan on printing so many other things like endcaps for staffs, and grommets/seals and the like. I'd like to build a beetleweight combat robot and a lot of the armour is TPU. I feel like this opened up a whole new avenue for printing nonrigid items, and has expanded the life of my Ender for much longer as that was a reason i had though about updating. 6 years strong and its been a beast!

Helped get rid of the slipping or grinding I would have, less mess next to the extruder. The Capricorn tubing is great, already had some on hand but I know that is amazing and definitely recommend if you have stringing or plan to print at higher temps. One issue I have which is not for everyone, but I installed this on a cr-10 v1 and was unable to use the extruder dampener, or the knob I had on the extruder to push filament through. Not a turn off for me but still with the gears sat a little lower so I could use my knob. Another thing I wished was on here( although it’s not on the original or the metal one by creality) is that the spot where the gears sit was smaller so that the Filament would not bend so much as it’s harder to get the filament through the second hole, especially when your filament breaks or runs out in the middle of the print. Overall I would still recommend as the issuers I listed are minimal and really not a problem for everyone and not even fixed on other extruders.

Works perfectly and now I can print using TFU.

My Creality CR6-SE got a clog and after changing the nozzle, it was performing very badly with under extrusion (thin filament and spongy, weak, and fragile. prints). I suspected the cheap plastic extruder was worn out, so I bought this relatively inexpensive metal extruder (silver, single drive). It was easy and low risk to install. After installing and putting on a new 0.4mm nozzle, my printer was back to printing very well. Very happy with the purchase, ease of install, and results. I'd highly recommend this upgrade if you have an older or plastic extruder. I can confirm this works perfectly with the CR6-SE.

Had the original plastic extruder and the arm portion snapped causing dashed lines on my prints, because the filament wasnt being pushed through properly. I didn't noticed the snapped arm at the time until I removed the extruder itself. The original brass toothed gear on the extruder stepper gear can be a challenge to remove. Eventually used a ligther to heat the brass to make the metal soft/expand, then used pliers to pop the gear off. I positioned one jaw of the pliers under the gear and the other jaw on top the stepper motor armature post (the post the gear is fitted on). Also made sure to keep the lighter's flame away from the stepper housing during the heating process. There might be a better way to remove the fitting, but these were the tools I had at the time. I can see using a demel to grind off the gear, but that might cause unwanted shavings in the stepper motor. If you still have the plastic version of the extruder, just upgrade to metal before you go insane from the troubleshooting causing a brain aneurysm. Extremely happy with this sturdy replacement and I can resume my printing!

Prodotto pieno di cose per aggiornare la stampante però nessuno di questi è veramente utile.. Qualità non molto alta arrivato già usato! Pessimo acquisto fatto il reso. Non lo consiglio!

純正のはプラなので経年劣化で割れます これはアルミなので早めに変えとけば良かった

Gekauft für mein CR-10 V2. Passt auch aber ich habe viele Dinge nicht beachtet/erwartet. Zum Beispiel passt der Filament-Sensor nun nicht mehr, man müsste ihn erhöht anbringen, da der Filament-Zulauf nun deutlich höher ist als mit dem original Extruder (siehe Fotos). Auf den Filament-Sensor kann ich zum Glück erst mal verzichten. Montage war trotz fehlender Anleitung einfach. Der Aufbau und die Schrauben sind exakt wie beim original Extruder. Nachdem ersten Druck habe ich bemerkt, dass ich vergessen habe den E-Stepper anzupassen. Also damit der neue Extruder auch exakt so viel Filament nach schiebt wie benötigt wird. Auch hier wäre eine Anleitung die erwähnt wie das geht nützlich gewesen, aber zum Glück findet man gute Tutorials online. Ich habe den E-Stepper also von 93 mm auf ca.139 mm erhöht wodurch ich ungefähr den gleichen Durchfluss wie vorher erhalte. Die richtige Einstellung zu finden ist allerdings schwierig. Hatte erst under extrusion und dann over extrusion. Ergebnis des Upgrades: Ich habe jetzt bei deutlichen niedrigeren Temperaturen am Hot-End immer noch einen konstanten flow des Filaments. Ich erhoffe mir auch weniger Verstopfungen in Zukunft. Spürbare Verbesserung im Druck-Ergebnis ist allerdings nicht zu sehen. Fazit: Man muss ein bisschen fine tuning betreiben um die richtigen Einstellungen am Drucker zu finden. Außerdem muss man wissen wie es geht, da es keine Anleitung gibt. Insgesamt finde ich das Gesamtpaket aber gut. Sind alles Originalteile von Creality und passen. Es wäre schön gewesen vorher zu wissen, dass man dadurch den Filament-Sensor unbrauchbar macht.

Muito bom

Super qualité , aucun souci pour l'installer sur mon ender 3 le tube capricorn suffisamment grand pour deux utilisation et l'extracteur dual beau et robuste, juste les ressorts de plateau trop grand mais un coup de pince coupante et c'est réglé
