Hey, everybody, what’s going on? Welcome back to my channel a couple of days ago. A buddy of mine asks me. Hey, Johnny, I know that you have 3d printers. I know that you’re good with cad. Is there any way that you would be able to design and print me a grinder and I’ll pay you for it and I said yeah. That sounds like a fun challenge, so I figured I would make a video taking you guys. Along with that process from designing the parts infusion to sending them to the 3d printer, go over a little bit of how a resin based printer works. And then what you do with the print once it’s done with the alcohol baths and the post curing, and then, of course, show you the final result, because I think that it’s going to be something pretty cool. Okay, so this is the design that I ended up coming up with. I’m pretty happy with. It took about an hour and a half to make for those of you who don’t know I do all of my designing on Autodesk Fusion 360. If you’re a student, you can get it free for three years. This was inspired by a design. I saw online, but I made a few tweaks to it to make it how I wanted to be. There were a couple of things that I really wanted to have one of them being. I didn’t want it to have any threads so instead of having threads. I have these neodymium magnets That are going to go here and here. I think this will be perfect so now that we have it designed. What do we do next well? First of all, we have to take the three files that we want to print the top middle and bottom, and we have to save them all as an STL. Once you have your stl files, we go and open prefor’m now. This is a software made by Forum Labs, the same company that made the printer. You insert them into preform and this is what’s going to Orient the print. This is what’s going to make it into something that the 3d printer can actually read and work with. I don’t want any support to be on the top of this leaf. I want it to look clean. I don’t want there to be any support points. I want all the support to be on the bottom of this middle section, and the bottom is just going to stay how it is because I don’t want there to have to be any points on the bottom as you can see on the side here. There’s a bunch of warnings that’s just because there’s not any support. Now we would just auto generate these because they’ll be fine for the most part, but there’s a few tweaks. I want to make just enough to keep everything in place will be fine. And also the smaller touch point will make it a lot easier to clean up. It’ll make the points break off a lot easier and they’ll be easier to sand and less noticeable. So what do we do now? Easy, send it off. [MUSIC] This line of dead pixels makes me so happy, that’s awesome! [MUSIC] All right, well, while this is printing, we have about eight hours to go probably won’t be already until tomorrow morning, so I’m not going to get this video done today, but I’m going to go over a little bit of how the printer works and what’s going on right now, so the printer that I’m using right now is the Formlabs form 2 It’s an SLA printer and SLA stands for stereo lithography. It’s different from the type of 3d printer that you’re probably used to seeing, which is an FDM printer like the one behind me The main obvious difference between these two machines. Obviously this one is enclosed and that one is not, but this one has liquid and that one obviously does not that one uses filament. This one uses liquid. The thing that’s special about this liquid, though, is that it’s actually photosynthetic and what that means is that when it’s exposed to UV light, it hardens and turns into a solid, so this is the build platform. That’s what moves up and down this tray and that black liquid that you see inside. That’s the photosynthetic resin that hardens under UV light. And that’s actually why this is orange. This is orange because this doesn’t allow UV light to get inside in here. Is the laser and that laser is controlled by a series of mirrors that are attached to motors when those mirrors turn, that’s what controls where the laser points so it’s printing a layer right now. When that layer is done, the platform will come up. It’ll swipe to make sure everything is nice and clean and good to go for the next layer and then it’ll come back down and it’ll come back down Just a little bit higher than it was before. When you take a print out of an SLA printer. It’s still coated in excess resin and the only way to get that resin off is to dissolve it in an alcohol bath. And then once you take it out of the alcohol bath. Just let it sit for a little bit. It’s good to go, all right, everybody. We have just over two hours left, and it’s a little past one in the morning, so well, we’ll see how this is. When I wake up, I did have to pause it for a little bit because I wasn’t going to be here and I wanted to be able to still get some footage of it mid. Print, I’m a little worried that that’s going to cause a little bit of layer splitting. What that’ll be is thatll. Just be like a a line going down the print because one layer where I paused it at is going to be just a tiny bit off from the layer on top of it for some reason that seems to happen a lot when I pause mid print and we’ll see how it is. [MUSIC] Foreign [Music] [Music] [Music] [Music] [Music]. Okay, here it is. You see this line and also this line? Those lines are the points that I paused at that settler splitting. I was telling you about it’s not a big deal. It’s super super minor, and it’s almost not even noticeable, but it’s still there and it bugs me. I’m super happy with how it turned out. The detail on the leaf is incredible. The magnets anyways. A little bit of info about this print that I didn’t want to include earlier in the video. Because I just didn’t want it to be too boring. I did print this. At a layer height of 0.05 millimeters that’s 50 microns, the printer can go down to 25 microns, but that just wasn’t necessary for this project. Not only would the print have taken twice as long, but there really wasn’t that much super fine detail on this to benefit from having a layer height that small the top pops into the middle, Just exactly as I wanted it to. [MUSIC] spin smooth. It spins freely, but it’s also not gonna fly apart. It’s not gonna come apart in a bag or a backpack or anything like that, and can we just talk about? How good the leaf came out. I mean, look at that. Look at how nice that looks, that’s the bottom. Well, thank you for watching this video, guys. I hope you liked it.
