3d Printing Tutorial: Platform Adhesion (skirt , Brim , Raft)


[music] you [Music]! Hi, everybody! Welcome to another episode of prints on one two three in this episode. I’m going to be talking about the different types of platform adhesion. So I’m here in, Kyra. I have a model open. This is the Incredible! Hulk, and we’re gonna look right here, And this is where we have our settings for our platform adhesion type, So I’m gonna go over the three different adhesions. You have, so the first point is skirt. The second one is brim and the third one is raft so by default. If you select none under platform adhesion type, this is gonna add the skirt, so that’s by default. So let me go over here to layers, and I can better explain what each of these three are so we can see here if we zoom in what a skirt is is basically just a single layer. This light blue line is representing the skirt and all this is gonna do is ensure that you have a nice even layer of filament before you go in and actually do your inner and outer shell and fill in your part on the first layer. So what’s nice about using the skirt is you can use it as a benchmark, so if the skirt does not come out. Well, then you might as well just turn your printer off and adjust your settings and reprint again because if the skirt doesn’t come out, well, your print is not going to stick well to the to the print bed, and you may have some issues as it starts to print so as a first pass. This is a really good thing to use to to know how the quality of your print is going to come out the second type of platform. Heejun, if you select here, you can go to brim So what brim is gonna do is it’s gonna add a couple outer shells that just barely touch. They barely kiss your park just so enough to help give you a little bit extra support. When you’re printing the first layer, so we’re gonna let this load load here so we could take a look. So these are our inner and outer shells of our part and what we’re gonna see is some additional layers. I believe you can adjust this setting, but typically you want maybe three to five layers so here. They just populated so these blue lines. Now show it’s going to add these extra layers just to help. Keep your print down and make sure that these first inner and outer shells really stick well to the parapet, and that’s going to help you Overall get a better quality print and the last option here is called a raft so what a raft is gonna do is actually create a platform for your print to build upon so instead of just bordering your print like a brim or skirt would do. A raft is actually gonna lay filament down on the bottom of the print bed, and so in this case in the Hulk’s feet, They’re not gonna actually print right on to your print bed. They’re gonna print on top of this raft, so let’s let this load for a second, and then we’ll be able to see what. I’m talking about there so one thing to note with the raft. Is that after you print your part? You’re gonna have to peel away the raft and break break the raft off from the part, so lets. Give this just a second here. Looks like it’s still loading. My computer is going slightly. Slow right now. Another thing to notice to note about the raft is when you peel it off. Sometimes the bottom of your print will be a little coarse, so that’s one thing to keep in mind. Where if you care about? You know, the bottom layer of the print just to, you know, keep that in mind so here we can see the raft is now showing up as our first layer, so what it’s going to do is create this first layer, and if we skip up, let me go up a layer to a couple layers, so we could see here layer three. This is where our raft is stopping, and if we go up, you know, just a little bit more. We could see the foot is now going to start to print on top of this raft, so this really acts as an interface between your print bed and object and it can really, you know, also help to to get some platform adhesion, so these are the three different types for most prints. I’ll just go ahead. Set this to none and use a default skirt for my print. I find that if I get that single line around my print. If that comes out well, typically, my print will adhere well to the print bed and I’ll have no problems. Sometimes if I download someone else’s model, they may recommend to use. Bremer raft and I’ll typically just follow their recommendation and use whatever platform adhesion they say so. I hope this lesson was helpful to you If you haven’t done so already.
