Alright so I want to show you guys how we used our extrusion machine to make 3D printer filament. Here's the extrusion machine from our videos and the shredded plastic is in here and gets heated in this barrel and then it comes out from the nozzle as you can see. So let me focus. And this is a key thing we make in filament to have a night solid line and this requires some tweaking and adjusting. So for instance these are the temperature settings we use and we also use controllable engine but you don't need this because you can also adjust with the nozzle, the output. But it takes you while before you have the right temperature settings so we're currently extruding polypropylene and this is what works for us but it depends on your type of plastic the environment, the speed, so like I said tweak a little try it out once you have it, write them down, never forget. So the extrusion is just extruding pretty nicely the plastic. And it goes onto this thing and this thing basically first thing it does is it cools down the plastic with some old computer fans and this is all just used for cooling to make sure it's cooled down before we're going to wind it up. So here is the winding up taking place on the spool which you can use on your printer and we can set the speed of these winding up over here and this defines how thick you want your extruded filament to be. So this is a couple of settings like the speed you'll currently the distance you've done so far and the timing. Again this also takes you while before you have the right settings once you have them don't let them go. And this is actually quite nice so this is just extruding you don't have to do anything with it. Once you have the right settings it's just automatically working for you. For this thing is still in beta but extrusion is pretty finished up. Go watch our forums to visit the blueprints of this thing and go watch our website to find the blueprints of the extrusion and that is no if you have any questions.
