 Hey, what's up folks welcome back to another layer by layer in today's tutorial. We're gonna take a look at this week's project It is a lemon keypad. This is a little 3d printed lemon keypad and in this tutorial I want to focus on the skin texture here So this is a new feature inside of cura That's called fuzzy skin and it gives the outer skin of 3d models this really fun texture Let me see if I can autofocus this There you go. So you see here. It's got this really cool Really rough texture, but it actually gives a really good grip to your print And if you have something visual where you need a texture like this lemon I think it's just pretty good way to kind of create this this this texture fairly easily and it's all done in the slicer You don't actually have to model this stuff. So here's that surface what it looks like with the fuzzy skin texture applied And here it is without the fuzzy skin texture applied nice and smooths. You notice that yeah, there's no texture that was modeled here It's just all done in the slicer. So let's jump into cura and find out some things about this so here I am in cura and Let's talk about the version of cura. This is version 4.8 There could be another newer version or rather an older versions Just make sure that you're on at least version 4.8 Excellent. Next I want to focus on is the the printing settings panel to pull it up There's this little search box here and you can just type in anything you want This feature is called fuzzy skin. So I can just type in fuzzy hit the enter key and here in under the experimental Tab you can see here. We have the fuzzy skin. It's when it's turned off none of the options show up So when you check it it turns it on now since version 4.8 there is a new feature now that is called fuzzy skin Outside only this is a really important feature because without this This wouldn't really work as a practical print. So let's bring in the model and I'll show you what I mean so I got my skin model and You can see here in the surface is not textured. It's all nice and smooth and Here with the fuzzy skin if you turn Normally before 4.8 before this outside only let's take a look at what it looks like when we just apply the fuzzy skin to this whole model takes a second for fusion to or For cure to slice it but under the pair you're not going to see it So let's go to the preview tab that gives you a nice visual render rendering And here you can see on the inside It is also fuzzy the outsides fuzzy and that's a big problem Particularly for the bottom pieces they need to be smooth Because that's how these pieces snap fit together the bottom cover needs these little pegs here to snap into and The kind of core area has to slide into this So let's turn on this feature now fuzzy skin outside only check that and Reslice it Let's see what happens alright, so We're getting better there. You can see in the inside. It's nice and smooth But as we get closer to the bottom You'll notice that there is some fuzziness going on and with these pegs here. That's gonna really mess things up So why is this happening? Well, if we look at the model, you'll notice that there's an opening here And this is like a port opening for the USB cable, right problem is because the model has that as an opening Cure really doesn't know that that is an inside feature It's just the nature of like having an opening like that So in order to fix that I kind of had to rework the 3d model, right? So if this is where the problem is happening I figured why don't I just close that off with a thin wall that way? I can just cut that out when it's done printing. So that's pretty much what I had to do So let me delete this model go back over to the prepare tab and then bring in my kind of optimized for fuzzy skin model so here it is version 2 and Right where the port hole should be you'll notice that it is now closed off And if we look on the bottom side, you can see that it's fairly thin It's only point two or point four millimeters thick, which is about the thickness of a single perimeter So that was really kind of the goal there to make it as thin as I can so that I can cut that piece out later So let's now that it's a fully kind of enclosed bottom when I slice it It should keep all of the inside nice and smooth So again, make sure our fuzzy outside only is checked and let's re-slice it And it takes a little bit of time to slice it, but You'll see here in just a second and our print time actually went down a little bit It's now three hours and 55 minutes So go under the preview tab and you'll see here that hey Everything is nice and smooth now. So this is what I needed to do in order to to make this To make this inside geometry still stay smooth And if you look closely at the thin wall It's so thin that the effect is kind of seeping through the other surf the other side Which is okay because that shows that yet is just a single line perimeter and I was able to cut that away So let's take a look at under the camera. I'll show you what that turned out like So over here you can see that it yeah, I did print it with a little bit of that Texture on the inside, but it's super easy to use an exacto knife or rather flush diagonal cutters to kind of trim this away And that's what I did over here and you can see my cables is in there Let me disconnect that real quick and then you can see here. I can still smooth it out a little bit I just kind of rough cut it out. I could sand that down if I really needed to but it kind of adds to the texture there So yeah, that's what I had to do. You can just optimize Any openings with a thin wall so that you can cut them out later Yeah, so jumping back over to cura you can see here that That's looking pretty good and it doesn't add too much time to your print You can see it's three hours 55 minutes and if I turn this off and slice it again It's probably maybe a half hour of extra time Yeah, it's about a half hour or so so three hours and 27 minutes without a fuzzy skin with a fuzzy skin 30 minutes extra to that So that's that's a this particular model now. I have some other ones that I thought would be kind of fun to play with Definitely do a Google search for fuzzy skin and you'll see what other folks are printing. There's some good videos By CHEP Andrew Sink also have some really good videos on on the feature Chip did a really good one with a handle for a knife that worked really well You see Benchie and some other things like a llama and animals is a really good Kind of way to use this feature, but also take a look at Agustin flowelistic who created a birdhouse Using this technique really really nice it actually does the whole thing for something like Like a birdhouse that has like this this concrete or this stone texture. It works really well for that Another one here is like a planter. I think planters is a really great way for to add some texture to that something that'd be really smooth and Then for our stuff I was looking at the cauldron that I designed for the circuit playground express last Halloween This would work really well with with the fuzzy skin and then things like this stand for For displays and Raspberry Pi projects I think a stand would would work really well too because it's printed tall ways And I could actually bring these models in just to kind of take a look at If there's any problems. So first one, let's do the cauldron And right away I can see that there's a bit of an issue here with the cauldron And that's this port opening in the back there So this really shows like even though you have so I'm going to turn on fuzzy skin Turn on outside only and then slice it while I talk about it Even though that the opening isn't on the bottom It's any opening. So you have a model like this where it has a hole You might want to patch that hole if if if you need to Have it as a part if it doesn't affect the inside, right? So in this in this model, let's see if that actually affects anything Yeah, so you'll see wherever your hole is the inner Walls of that will also be affected Um, and it's only the z as you can see here. There's like some flat surfaces. Don't get it Those do not get any texture. They're just kind of flat top and bottom surfaces, but On the outside, it looks great, right? But uh, if you look here, there is a coil, right? There is a thread that's on the inside that remains Smooth, which is great. And then as soon as that opening happens all of the kind of inner wall area get turned into the fuzzy skin and For this particular design Because of the threading it should work. Okay, this wall here doesn't really do much for tolerances on any of the other pieces It's just the bottom piece that needs that so this one Even though it has a hole in some of the inner geometry is being affected It's actually okay. So it really depends on like your project the fitting of it Does that geometry on the inside matter if it's smooth or not and with practical prints that have multiple parts That's something you got to think about But for this one, it's actually a lot easier I don't have to do a special model just to get my fuzzy skin to work out really well I haven't printed this out, but I'm sure it looks pretty neat So that's one piece there and that's just another look at The kind of problem solving if I need to or not and with this one. It's actually kind of fun I don't have to do anything extra And then the last one I wanted to show was the uh, the stand for the mag tag That's an ink display It kind of has like this santa sleigh magic carpet style Shape to it. So I think for this one it would work really well in this one Inside or out it it doesn't have an inside really because it's all just there are holes in it But let's see what it looks like, right? This is one of those case where I haven't actually printed it yet But I think it'll be okay Because the holes there you can just kind of tap them with a screw tap just to smooth out those holes So here's what it looks like it does add a little bit of extra time here But yeah, it's it's a stand the inside is the outside as well. So There's not much of an inside right like those holes right there It doesn't know that it's an inside because it's a hole and as we showed holes are a little bit of an issue But I think this would print okay It's fairly thick. So so that should hold on to the bed. Okay, but of course you can add A brim if we need to as well some things. I didn't talk about it was like the these these actual These actual values here you can of course you can modify them But I haven't really played with that these are default settings that I've just used and they seem to work Okay, but as you play around with them, you could to change the scaling of the effects if you want bigger Um Bigger textures. I suppose you can change that up, but I've been using the default which works pretty well This makes me think of like some other type of food. Maybe some weedy things or What is it some some ramen noodles or something could it's more food, right? I'm hungry But other than that that's the feature that I wanted to take a look at today Um, check out the links in the description if you want to build your own a lemon keypad Uh, that's going to do it for me, but until next time remember to make a great day. Bye folks
