You can cool the Filament using water or air. We recommend using an air cooling system, because water cooling is a complicated mess and as long as you are making less than 3Kg/h an air cooling system works just fine. The most simple and cheap method is using a tower ventilator which you position horizontally under the filament. We use our own cooling unit, the JARVIS Airpath. Its fans can be controlled precisely in order to harden the filament but keep it soft enough to easily wind it on spools. The winding process will work best if the single filament tracks stick to each other slightly.\n" - text: "Finally, the filament can be wound onto a spool to be used with a 3d printer later. You will need a filament winder which should have a pull unit, a guider (to spool the single tracks from one side to the other) and a turning spool axis. An important factor to look out for when buying/building a Winder is that the filament always stays on tension so you don't end up with loose spools.\nFor this step, we use our JARVIS Winder; a winding unit that adjusts its spool motor speed automatically and makes perfect winding possible while maintaining the diameter of the filament as well. Simply insert the filament into the puller, thread it through the guider and then into the spool." title: "Winding" images: - name: "1 Winding.jpg" type: "image/jpeg" fullPath: "uploads/howtos/CXK8RtQGUVn4kCMdh3XJ/1 Winding.jpg" timeCreated: "2021-08-12T08:57:14.076Z" downloadUrl: "https://firebasestorage.googleapis.com/v0/b/onearmyworld.appspot.com/o/uploads%2Fhowtos%2FCXK8RtQGUVn4kCMdh3XJ%2F1%20Winding.jpg?alt=media&token=15b5ec7e-31c7-46e1-8ba1-32c52da8fbbc" size: 110789 contentType: "image/jpeg" updated: "2021-08-12T08:57:14.076Z" - size: 129298 downloadUrl: "https://firebasestorage.googleapis.com/v0/b/onearmyworld.appspot.com/o/uploads%2Fhowtos%2FCXK8RtQGUVn4kCMdh3XJ%2F2%20Winding.jpg?alt=media&token=d18b632b-2898-453a-b049-8d83a1eaf50d" name: "2 Winding.jpg" contentType: "image/jpeg" type: "image/jpeg" fullPath: "uploads/howtos/CXK8RtQGUVn4kCMdh3XJ/2 Winding.jpg" updated: "2021-08-12T08:57:14.061Z" timeCreated: "2021-08-12T08:57:14.061Z" _animationKey: "uniquedrw2km" - title: "Printing" images: - downloadUrl: "https://firebasestorage.googleapis.com/v0/b/onearmyworld.appspot.com/o/uploads%2Fhowtos%2FCXK8RtQGUVn4kCMdh3XJ%2FBildschirmfoto%202021-08-12%20um%2010.39.12.png?alt=media&token=d79c94e2-2737-4992-81ae-ddb907061cbf" fullPath: "uploads/howtos/CXK8RtQGUVn4kCMdh3XJ/Bildschirmfoto 2021-08-12 um 10.39.12.png" size: 130850 name: "Bildschirmfoto 2021-08-12 um 10.39.12.png" type: "image/jpeg" updated: "2021-08-12T08:41:26.882Z" contentType: "image/jpeg" timeCreated: "2021-08-12T08:41:26.882Z" _animationKey: "uniquewryu8y" text: "Now you can put your brand new filament to use with a 3d printer.
