Both parts have the same issue, so we recommend replacing both.
There are two different sizes of these couplings a smaller size connects to the extruder, and a larger size to the hot end. It’s also a good idea to have spares of these pieces, since you can’t print at all if they fail. The stock couplings use plastic “teeth” to hold the Bowden tube in place, so we recommend picking up some improved F1RST LAYER couplings with metal teeth which will last longer. Once they have failed, you can sometimes reconnect the tube, but it will fail again quickly so we recommend you replace them if this ever happens. When these fail, the Bowden tube will detach, and the filament will start coiling outside the printer. Metal Extruder KitĪnother component that will commonly wear out over time are the couplings that connect the Bowden tube from the extruder to the hot end.

However, there are a number of extruder upgrades that we recommend, and we’ll discuss them in this article. We typically use stock hot ends on our printers because they work great out of the box. The hot end is where the filament is rapidly heated and melted immediately before becoming your 3D printed part. The extruder is on the left side of the printer and is what pushes filament through a tube to the hot end. Some are also compatible with other printers like the CR-10 (we will note these in each section).īefore diving in, a little background: The hot end and the extruder are the most important parts of your printer to maintain, since both see the most wear out of any other part and have the biggest impact on print quality. We've also tried a few upgrades that we don't think you need, and we'll talk about why to save you the trouble and expense.Īll of the Ender 3 mods we recommend here can be used with the base Creality Ender 3, the Ender 3 Pro, or the Ender 3 V2. Each of these upgrades are fairly easy to install and just require the tools that come with your printer. Although there are many Ender 3 mods online, we feel that these particular upgrades provide the most improvement for your new 3D printer, including improving print quality, reducing maintenance, and preventing frustration chasing down problems down the road. These Creality Ender 3 upgrades are the ones we think give the most bang for your buck, and are upgrades we’ve applied to the printers we use to make sure they can keep up and running with minimal maintenance.
