Hello, everybody and welcome to a new episode on 3d printer guides and today. I will show you how to calibrate the extrusion multiplier or flow rate. What exactly this is? You will find out in this episode. Enjoy yes. I mean, I talked about the calibration of our 2d printers in nearly every episode. Right now this is very important, and today we will begin by calibrating the extrusion multiplier. But why we need to calibrate this. I mean, maybe you found out something or that. Is something wrong with your print specially? When you, for example, print a cube with a line width of zero point four millimeters and at the end, you measured your one wall and find out that you are that this wall is to a thin or thinner than 0.4 or thicker than 0.4 and this means that your extrusion multiplier or flow rate isn’t correct and this we have to calibrate now that at the end, the exact amount of material comes through our novel into your object so very very important, and I mean at the end. This is not really really hard to calibrate. You have to make a one or two test prints and you are fine, but how does this work? I will show you that. So first, of course, we have to decide which slides a program we will use in cura. We will talk about the flow rate. You will find the flow rate under material. So, of course, this has something to do with material and the standard setting is 100 percent. When you use simplify or other slicer programs, you will have a extrusion multiplier setting, which could be a 1 or something like that so different, but this doesn’t matter at the end. We will do some calculations, and then you will find the right setting for your slicer program so but just keep that in mind that or in simplify, we’ll have an extrusion multiplier, which is mostly one number, so just keep that in mind very, very important. Okay, but what should we do to calibrate the flow rate for this? We will have, or we will use a small cube so very important we. I will use a layer height of 0.2 and this is the important setting. You should keep in mind the line width. So, of course, you can use every line width, and at the end, we will just print one wall and, of course, at the end. The wall should be exactly this setting in my case Now. Zero point four, very, very important and also very important. We will just have one wall, of course, also very important to measure this and this is it so we won’t need any infill so that we will just print. Let’s slice this and you will see this that we just will print one one wall very important, but we also doesn’t need any top or bottom layers so also very important, make top layers, zero bottom layers zero. Here we go and now we are fine and we just have the walls on the on our object so very important here. I don’t know why this cube is here. A little bit broken. I have no idea, but again At the end, this doesn’t matter. We want to measure the wall thickness so very, very important. A very fast print as you can see 10 minutes and this. Then you have to print in the first step again. Just leave all the settings standard, take a look at your flow rate or extrusion multiplier that this is and 100 percent or just the standard settings and because from this, then you can change the setting, then when you measured everything so yeah, this is it print. This and you are fine. When your print is finished, of course, next step will be you have to measure the wall thickness, so use your tool measure the wall thickness. My recommendation is measuring all of the walls and take the average so very important. But I mean, you can see this right now. I definitely have too much material. The wall is now here. Something like 0.45 This side is 0.47 This is again 0.45 and 0.45 So I will then go to the calculator. 0.45 Three times and 0.47 four sites. And this is the average I measured right now and we should have. Of course, the best result would be to have 0.4 means. Now we know that my flow rate is too high because I have more material than needed, and that makes my wall thicker, of course, so very important, but how we can calculate that this is very easy. There’s a very easy formula to do in death, so you have to use your current extrusion multiplier, so the standard you have said on your slicer In this case, my flow rate 100% multiplied with the extrusion width. This was 0.4 Of course, now this to my measured average of the walls 0.45 And this is then my new flow rate in this opinion in this case here, so very important now. I will use this setting here and go to my flow rate, set 88 or 0.8 So this is my flow rate. I measured right now. And, of course, next part will be printing This cube again, measure it again and see how everything Yah works then, but hopefully this is then the correct flow rate for my ya printer, so Q print it successfully, and, of course, now measure ring the wall thickness again, but as you can see, not quite perfect, but much closer than before so very, very close to the perfect result. Maybe 0.43 0.39 but in my opinion, a very good result, and I’m happy with this, but, of course, now you can do another calculation if you want to, and maybe try to find a 100% way, but this is absolutely OK. This is the tolerance. I I can live with, but yeah. This is the way to calculate your extrusion multiplier and again. This is very important that at the end, the exact amount of material will go to your 3d prints so very important, but if you have the problem that your walls are too thick or too sin, you will know now how to fix this because then your extrusion multiplier or flow rate or other names in different slicer programs isn’t correct so very important and also very important to see that is necessarily to. Yeah, calibrate our soda printer, and there are so many other positions you have to calibrate, for example, of course, these steps or the the. D hide or whatever, but all very important parts and hopefully. This was a little bit interesting for you guys if you liked. The video hit the thumbs up. I would really appreciate that.

Then a new episode of one week wants to reprint the cool creation from a cool creator. Check this out. But, of course, now, the most important part guys wish you a rest pleasant weekend. Take care of you! Stay healthy and hope to see you next. Saturday, then for one week, once we print this. Is it for today? My name is Alex. And that was 3d printer guides [Music] [Applause] you?
