The Bowden drive is one of 2 common features of a desktop 3D printer. This device helps to feed the filament to the hot-end of the printer. Unlike the direct printer, the Bowden drive has a tube that the filament moves through before it gets to the hot-end extruder. The Bowden drive helps to lighten the moving parts of a 3D printer and results in a more accurate print job. It is also praised for making the printing process faster than when you use the direct extrusion method. The Bowden drive can move much easier and faster which is why the printing is a bit faster and more flexible.
Bowden drives are usually installed in the tall delta base printers as it is much easier to accommodate the tube but in some Cartesian 3D printers, you can also install the Bowden system. Basically, if you want to improve the quality of your 3D prints, it is best to use quality Bowden drive instead of the direct drive. However, it is also important to know that Bowden drives are not recommended for flexible filaments. Most people who have complained about their Bowden systems, do so because they are using the wrong type of filament. Bowden drives tend to have blocked tubes when flexible filaments are used. This is because when flexible filaments have to move through a long tube, the pressure exerted on them to move, ends up making them flex instead so they will get stuck in the tube.
Always ensure that you are using the recommended filament for the Bowden drive. If however, you end up with the filament getting stuck, it is not difficult to clean the tube. An expert will have it cleaned in under an hour. It is also possible to do it yourself as all you have to do is remove the filament and then clean the tube and reinsert the right filament. Bowden drives are much more accurate so if you are doing printing that requires a high amount of precision, you will want to use a Bowden drive. What’s more is that you will be saving time since it prints faster than most direct drives. To ensure the perfect print job, it is important to carry out calibration before you begin printing. Calibration ensures that the Bowden drive will feed the right amount of filament needed to ensure the 3D print is not too thick or too thin.
Calibration should be done periodically as well as part of the maintenance process, this will ensure that the drive is always working at optimum level. It is important that you purchase original Bowden printer drives from legit dealers to ensure that you actually enjoy the advantages of using the Bowden drive for 3D printing. Some of the cheaper brands may not be authentic and they will end up botching your print jobs. Bowden drives are best used when you want to make a number of prints in the shortest time possible with fewer adjustments made.
