The BMG features a gear ratio, the perfect combination of speed for high flow applications and precision for tiny-nozzle, high-resolution parts, and accurate retraction. From rigid materials like PLA to super-flexible filaments like NinjaFlex, the constrained filament path of the BMG makes this a great choice when building from scratch or upgrading your existing 3D printer for better performance.

No matter what your use case is with 3D printing, absolutely everyone can benefit from enhanced extruder performance. The Dual-Drive gears of the Bondtech BMG create constant contact with both sides of the loaded filament, allowing for greater grip during both extrusion and retraction operations. Not only are there hobbed gears on both sides of the filament, but they are geared together to apply pressure evenly on both sides of the filament at all times.

Idled extruders leave room for slippage as the filament can simply slide along the bearing if pressure is too high, but Dual-Drive ensures constant grip over a much larger pressure range. The most significant growth in the 3D printing world today is the constant stream of new and exciting materials being manufactured for desktop 3D printers.

Entry-level materials like PLA, ABS, and PETG remain available in a wide variety of colors from many manufacturers, but stronger, reinforced composites are becoming more prominent every day. This abrasion is a concern for 3D printer nozzles, but also for the extruder gears that have to control this material going into the machine.

All Bondtech extruders are built with hardened steel drive gears with CNC-machined teeth for maximum grip.

Using a Bondtech extruder means peace of mind no matter what materials you are processing, from high volumes of PLA for prototyping to kilograms upon kilograms of carbon or glass-fiber reinforced materials. Every 3D printer hotend shares one thing in common, the filament must transition from a large diameter into a smaller diameter to pass through the nozzle and be added to a 3D print.

This transition is made possible by heating the filament, but even at extrusion temperatures, there is pressure to overcome when extruding material.

While most Nema 17 stepper motors are capable of producing enough torque to overcome this pressure, there is still a speed limitation.

To overcome this, Bondtech has designed the BMG with a gear ratio for triple the torque output, even in this compact package. This gear ratio is a great choice because not only does it provide additional torque but does so without sacrificing speed.

Another benefit of this gearing is the ability to create smaller extruder movements with increased precision over direct extruders. Not all 3D printing filament is created equal, and while most are rigid plastic that easily flows through the extruder and to the hotend, thermoplastic elastomers like NinjaFlex and MatterHackers PRO Series Flex have the consistency of cooked spaghetti and have a tendency to travel along unwanted paths, leading to failed prints and other hardware issues.

This design constrains the filament path from the entrance, through the dual hobbed gears, and out the exit of the extruder, leaving no room for flexible materials to turn sideways and cause a misfeed. In the same way that every maker is unique in their use case, from the hobbyist experimenting with new materials to mass-manufacturing operations who rely on 3D printing to run their business, every 3D printer and filament are unique in their own ways.

Having the ability to adjust the grip strength or tension of the extruder is a key element to adjust when setting up and fine-tuning any operation. The Bondtech BMG features a thumbscrew and spring mechanism for adjustable tension without needing special tools while maintaining the ability to handle slightly out-of-diameter materials.

Filament tension is something that may need to be adjusted due to changes in material or hotend configuration, and not all extruders make it easy to adjust on-the-fly. With a Bondtech BMG, you can constantly keep your extruder tension just right with the easy-access thumbscrew.Recently I've been trying to get the best quality possible out of it, and so decided to switch to a direct drive.

You can read more about it here. I wanted to spend the least amount possible - hence, buying a direct extruder such as the titan or a bmg was out of the question. I decided to use the original extruder. Some might argue that it adds too much weight, but I think the glass bed will be more impactful on maximum printing speed.

Also, the results I've read from other people doing it have all been great. In parallel, I also wanted to upgrade my cooling system. I already had a petsfang, which is incompatible with the direct dive mod I chose, and being obsessed with silence I figured two blowers instead of one would enable better performance with less noise.

Make sure to print all required parts before starting the build, as otherwise you will be unable to print. If you search on thingiverse there are many adapters to turn the ender 3's stock extruder into a direct drive. I decided to go for this one because it fit my criteria:.

Once printed, you need to insert the two printer's sleeves into the print holes. They are very tough to fit, I eventually melted them in with my soldering iron. Finally, don't forget to print the endstop to stop the stock motor from slamming into the frame! The next thing to do is install the dual blower part. I printed the BLTouch remixbut if you don't have one, you can print the part without the bltouch mount.

Warning: unfortunately this part won't fit in perfectly with the direct drive adapter installed. You will need to remove some plastic, or print my remix. There are two screws, but don't screw them in completely just yet, as we will need to check height after installing the hotend and nozzle.

You need to cut a bowden tube to just the right length, so it can fit between the extruder and the hotend.

This is a lengthy process that should be done carefully as ensuring a fit tube will avoid clogging problems. Don't hesitate to cut the tube longer that necessary and then adjust. For the hotend cooling fan I printed this cooling duct. It's a snap-on, easy to install. You're supposed to be able to slid it in, but I couldn't manage to do it with the hotend already screwd in. So I snapped the hotend in the part first, then screwed the whole thing in, then added the fan.

Once the hotend is installed, check if the leveling of the fan ducts leaves enough clearance for the print - so they don't scratch against the surface. Then, screw in the assembly completely - but not too tight, or the plastic will crack. Looks very promising!

At some point, however, you come up against the limits of these two printers. With the Bowden systems used, sharp and precise corners and edges are hardly possible.

Also, errors like stringing and other problems creep in through the standard drive.

With a direct drive, the extruder is mounted directly on the print head, which means less power is required for extrusion. The advantage of having a direct drive for your Ender 3 or Ender 3 Pro is that not only can you minimize the problems mentioned above and print more accurately, but you can also print better with flexible filament. For example, the distance between the nozzle and the extruder is shorter, which helps with the retraction of the filament.

The Ender 3 and Ender 3 Pro owe their popularity to their low prices, high quality and upgradeability. Both printers are using a Bowden extruder. In this system, the filament runs through a PTFE tube, that may cause feeding problems. This in turn can cause problems with the filaments. However, with a simple upgrade to a direct drive extruder, you can improve overall extrusion.

You will also be able to print with more flexible filaments. This means that the motor can push the material out of the nozzle more easily and is not as powerful as with Bowden extrusion.

In addition, the retraction is faster. The space between the nozzle and the extruder is also smaller. Prior to presenting you with step-by-step instructions for installing a direct drive system for your Ender 3 Promake sure you do have all the materials and tools you will need. Also, you need to know that this manual only shows one method. There are also other ways to install this system. You can choose from different kits for converting Ender 3 Pro to a direct drive system. However, in this guide, we will think about the possibilities for you to get a cheaper setup.

Such a system requires only one cheap part and a 3D printed part and some tools that come with Ender 3. Keep in mind that this design will work great for its designed purpose and will cost only a fraction of the money a kit would cost.

While a kit may be a little easier to install for some of the users and offer more stability. But we will guide you through the whole setup for the more cost-effective DIY direct drive setup.

On thingiverse. Proven settings are:. Using supports while printing is no bad idea. A brim can help with bed adhesion. When the print speed is too high at this setting, the print quality could be noticeably reduced due to the total weight on the nozzle. Increasing the speed to maintain a relatively consistent print quality is always possible. First, however, it is advisable to perform a few tests. You can also set these settings a bit higher if you see a lot of strings.Showing Slide 1 of 1 - Carousel.

It's the easiest, most feature-rich direct drive platform available for your Creality 3D printer, with no firmware coding or permanent modifications required. It's compatible with virtually endless combinations of hot ends and extruders, but was specifically engineered to convert your stock components into a powerful direct drive system with no additional hardware or wiring needed. Our products are proudly engineered and manufactured in our facilities in the USA, and come with an unconditional service and quality guarantee, as well as basic phone and chat support.

We chose to listen closely to our valued customers and community, and in the process made some significant improvements for our new v1. It's now more widely compatible, with more hot and and extruder combinations than ever.

Ender-5 versions do not require a belt adapter for linear rail mounting, but do require an additional bracket due to the top-mounted orientation of the rail on these machines. See our downloads section for updated, v1. Please note that this table and all associated links are under construction. If needed, please submit a ticket and request the files for the specific combination you require. Update - To make downloading the correct files easier, now simply select your desired combination of hot end and extruder from the drop-down list:.

Base weight: This table is for educational purposes only, and is a work in progress. Base weights are measured sans motor and cooling fans in some cases, as these may vary by application and manufacturer. Speed estimates represent real-world, draft- or better quality estimates derived from considerations like hot end volumetric flow, effector weight, and our combined in-house and community experience.

Bowden style extrusion systems like those found on Creality printers rely on long PTFE tubes to feed filament to the hot end, and as such are more prone to extrusion issues.

While Bowden setups generally allow for lighter print head weights, mounting the extruder separately from the hot end comes at the expense of less precise extrusion control, greater retraction distances, and more cumbersome filament changes.

By contrast, direct drive extruders eliminate most common extrusion problems by mounting the extruder and hot end very closely together, removing the bowden tube and drastically shortening the filament path. While this approach can significantly improve extrusion and retraction, and allow for easier printing of difficult materials like flexible filaments, it also increases the weight of the effector head. Even when mounting a full-sized stepper motor and the stock Creality components, the MDD v1.

Because the MDD is completely modular, it enables some of the lightest direct drive combinations in the world, with some combinations weighing less than g! Because of this, the MDD is light enough to print fast in almost any configuration, while solving many of the extrusion problems inherent to bowden-type systems. And because it entirely replaces the hot end carriage, it provides a vastly more rigid mounting platform for the extruder and hot end compared with printed direct drive mounts, which are more prone to vibration and ringing when printing at higher speeds.

A: No, a dual lead screw setup is not needed for the MDD, even when using a full-sized Creality stepper motor.
