Your cart is empty.This is V2.1 Bowden Extruder DDB Universal Geared Extruder Kit with RNC Nano Coated Gear for strength and life increasing. The lightweight design helping it to mount on various printers and provide a fast feeding and extraction solution that brings to you a completely new printing experience. Upgrade Highlights: 1. The position of the gear and the accuracy of all screw holes are calibrated. 2. Modified the new buckle, both sides of the V2.1 version of the DDB extruder support filament running thru in and out (it has no specified direction, and you are able to use either side of the material ports) 3. The filament has an independent motion cabin inside the extruder. The new white filament guide inside the extruder is helping the filament running smoothly. 4. The new outer shell design with edge cut on the top of the extruder is reserved for the screw rod of Ender 3 printer. 5. Upgraded shell using new mixed materials ***Please make sure Gears are Installed and Precisely Aligned before printing, they will perform successfully

I was cautiously printing 95 TPU at 10mm/sec; 0.1 mm layer height, using one those replacement red aluminum extruders (the original broke) on a Tevo Tornado, afraid to take my eyes off it for a minute due to frequent jamming.Now, using this product, I'm up to 35mm/sec at 0.2 layer height with good quality, no jamming or failures (so far).Given the low cost I expected to make some minor modifications. I added a 3mm diam. washer above and below the idler gear and at the bottom of the pressure arm to eliminate any vertical travel and thus keep the gears in line. I installed the brass gear upside down from the instructions for easy removal and installation to no ill effect that I can detect. The installation was general very easy.One other important caveat: due to the gearing I had to almost triple the eSteps to nearly 400 steps/min. My Marlin firmware setup supports this but I've read that not all standard software setups will do so.

Comes in a nice little hinged plastic box, but with absolutely zero documentation. The only reference to there web url is a tiny blurry bit of text on the box label. On going to there web site there was no documentation on assembling or installing or configuring software. There were some pictures on the product page, actuall a subset of those on the Amazon page. For example, the picture on the Amazon page of which way up to install the drive gear on the motor is nowhere on their site! I was installing it as a direct Extruder, but they call it a Bowden Extruder but there does not appear to be anyway to put a pressure fitting on the output side of the Extruder, so I have no idea how you’d use it in that setup, even though the provide a bracket that appears to be for mounting it that style! And there are two washers that show in the pictures that don’t seem to be in the box (maybe they are installed somewhere on it but I didn’t see them, and there is a little Teflon feeling washer included that doesn’t seem to be shown anywhere. Also, no where on their site or in the pictures or description on Amazon could I find the steps/mm setting for it - I finally found it in one of the questions on Amazon! If I were buying a BMG clone again, I’d look for a different one. I must say, it seems to work fine one you work through the lousy documentation.

This is my third extruder this style. First one was black, had so many jams the arm broke. Second I got a clear one. I could see jams as they started and had more understanding to dial in print settings. Better but still occasional jams. Now this one, printing good TPU, faster, with no jams.The price jump to this version had me on the fence, and thinking about it for a couple months, but I must say I feel, now, it is worth it.No jams, without dealing with settings to try to alleviate jams I am focusing on quality and speed settings. Print quality was good to begin with, just getting better and faster!This extruder has been a huge improvement for my TPU dedicated printer!

I bought a new Flsun Super Racer about a week ago. It worked for two days, then it started having extruder issues. It began with the extruder skipping extrusion with a clicking sound when it started to print. I checked to leveling of the bed several times, then adjusted the Z height, still it wasn't right. When I got this one, it immediately forced filament out of the nozzle. It came without instructions, but a few minutes had it fully assembled and working. It worked right out of the box and continues to do so, well worth the money.

Update 3/24/2023 I had to file down the small Allen screw that secured the main gear and now this BMG clone is working. The Allen screw was a bit too long and kept the gears from meshing together properly. Before filing down the Allen screw the extruder would skip. It’s working correctly and extruding as it should. I updated to 5 stars.I have 3 of the BMG style extruders running direct drives for the three different printers. I bought the cheaper 3Dman extruders and although quality is hit or miss with those extruders, this one I paid almost $47.00 for it. It has given me more problems than the cheaper ones. It slips, the door gear needed a washer to keep it in the correct alignment with the drive gear. It seems the teeth on the gears that grip the filament just don't grip well. It is a quiet extruder though.I kept hoping this would be a good extruder considering the price I paid but the cheaper ones actually work as good if not better. maybe I just got a bad one. it the parts bin it goes...

Installed this on my Ender 3 v2 and it works really well. Gotta print the bracket for it first though. Really great that it's dual gear and has 3:1 ratio i believe.

Precise and quality construction. Worked flawlessly day one. Using this on a direct drive setup in my Ender 5 Pro. As a precaution and to minimize wear, I lubed the gears before installing, just be careful not to spill over the filament area. I read and watched quite a few reviews before purchasing, and I could not be happier.
