 So hello, actually, my name is Slayton and Shree in the following slides, you'll know about my real name. So about myself. So, yeah, I said my name is lightning three, my given name is my name is my name and given name is given name. So I was influenced by lightning McQueen so so that I kept writing McQueen name and okay so basically I'm a student doing my diploma in mechanical engineering and my interest in embedded system and electronics and robotics. So that's where like I'm being in maker space hacker space doing some cool electronics like a person projects for that and short term goal is learning FPGA and yes, and you can scan my you can scan my website or you can scan you can follow my YouTube channel and Instagram Facebook and LinkedIn LinkedIn So okay so this is about me and next okay so the slide is not finished but so it's okay. So today I'll be presenting on new hack on 3d printing so how many of you like 3d printed something some of them okay many of them awesome cool so 3d printing is awesome technology right so initially when I used to see my father's factory my father has a factory and he has a machine shop. He used to say he used to keep the metal piece and he used to machine the metal piece so it'll be boring there'll be no interesting in the machining part of the site will be machining the machine will be going will make some noise weird noise. So it'll be like people used to stand there and see for the mission how it does, but it's not so interesting like 3d printing 3d printing is a technology where all all kinds of enthusiastic or maker or like non non maker also was the point of 3d printing they want to make some additive manufacturing process so so many of them, many people from different background contributed different things to 3d printing that's where like huge evolution of 3d printing technology like still now with like printing organs 3d printing organs it's like awesome, it can 3d print organs, maybe you can 3d print your hand in the future. So in this talk I'll be talking about triple f and fdm printers so basically, if you're not in India, they're last okay triple printing okay 3d fdm printing okay no problem. But if you're in India they'll ask okay triple what's the full form of triple f because when I was last year when I gave my SAT exam and India my grandfather suddenly asked what is the full form of 3d printing. What is the full form of the city? Is it full form of the city? That was not in the quotients. I don't know what is full form of the city, but if you go into India and if you say some kind of a short nickname and short name, they used to, what is the full form of them? So in this slide, I'll explain what the full form of triple F and FDM printer, they're both the same thing. Use filament fabrication and use the position, the position modeling. That is the full form of it. If anybody asked you can say that. And now, okay. So what is next to everybody last part is triple F printers and what are the kinds. So these are the triple F printers, FDM printers, they both are similar, just different names. And recently, like technologies boomed out. So there are, this is an ancient technology and pretty obvious than makers use this. But recently, most people prefer SLA, SLS, which like recent printing with UV light technology to cure and SLS is like sintering like metal parts layer. Yeah, powdered metal will be poured in a certain region and due to the heat it will, the metal get fused with the other layer of metal and you'll get a metal extruded 3D product. So many of the aeronautic industries or some of the robotics industries where they want like pool, strong parts for their bicycle or strong parts for their aircraft engines. So they can use the SLS technology and do this. So next, yeah. And cool thing is like if you want to, if you don't have a 3D printer like me and if you want to 3D print things, you can come to Hackerspace and you can join us a member and you can print your cool things. So that's was a free tip. Okay, disadvantage of this old ancient technologies like you can't print complicated shapes in this 3D printer. And if you print some tedious shapes, you will end up in the support structures. Maybe I will explain the support structures later if you don't know. Overhanging prints are complicated, you can't print about like certain angles. If it like overhanging like 90 degree, you need a lot of supports. So breaking the support is a tedious task, only 3D printer who like the person who handles 3D printing or who makes like, who prints stuff right, they know like breaking of the supports. Sometimes you break the supports, you will break the part out, part also. So just like so patient you require, you need to remove it and you need to do like post workings are like. We have plenty of post workings like filing it, smoothing it down. So yeah, too much of filament is wasted. You're wasting the materials. So whenever like, not in India, most of the people like saying plastic, not good for environment. You should reduce the plastic, not good for things. Plastic is abolished. So we make this, we also know like plastic is bad thing. So we need to reduce the support structures and we need to reuse the filaments again. So in this ancient technology, filaments like used very massive like in larger quantity. And yeah, it was like printing the 3D printed part with a lot of supports. It's time consuming. So if you want to print a small part for five minutes, but due to support, it becomes still minutes. It's like it's doubling your time. So time is very, very important. Time is everything they say. So if you're consuming a lot of time in here, your work, everything is like lag behind. So time is very important. So these are the four disadvantages I see from the triple printer. So how to have three stuff with the new technology to hack this disadvantages from the triple printing. There's a new method that method is developed by a software engineer. So is your software engineer, we hardware engineer like we hardware engineers. We do pretty good stuff. We build stuff, but we need some kind of a software persons to make the neural activated or like some kind of a boost or some kind of a drink actually make us like engineers are the builders. Okay, we build things, but software engineers are like the tonic bottle thing right when you drink the tonic something goes to your brain and you do something some activities. So software engineers are like very great. And they're like, I forgot the God's name. Yeah, exactly. Yeah. And okay, so the new, the method of of printing this out here. The new method is like over are overhanging method that is the developer kept the name are overhanging method. And it is known as midair printing printing the midair without support you print in the midair. So, yeah, this is the overhand printing. So you'll make arts. And without what you'll print overhanging. So this is the G code. Like you, if you want to use the code, you can use this. This is done by the developer. His name is Stephen. And that is a rainbow wish list. It's complete. That's on Python. Yeah. So personal experience actually, I will. I have to see in this queue, cool technology, right? Basically maker wants to test it out. Yeah. When software people like, I don't know like whether it's true or not software people are like too lazy. Like, okay, could I, could I move and could I just do the things. So harder people are like quite energetic. We need to try that out. We need to figure that out. We need to make that out and we need to test it out. So with the enthusiastic and with the, with the, with the curiosity I want to test the software part. So I don't know the software. I read about the GitHub page where how it was done. So, so then, then I got a few samples from the GitHub only. I printed this stuff. This part was cool, but it needs pretty much of cooling, cooling need to be added to your printer. And this was the, I have designed this stuff, but it didn't come properly. So maybe I need to do a little bit of engineering in this figure, which is the best part. So I'll do the parts to you. You can just visualize the parts. And okay, the model was generated from the website. You can, you can go to the website and get the model, or you can, you can also generate the model and you can do it. And Cura, recent Cura version also has the overhang prints. So you can download, you can uninstall if you're having the older version of Cura. Maybe if you install the latest version, you can print the overhang prints. And yeah, you, for printing this, you need extra fans to cool your printed object. So if you, if you have printed is a printed object is high temperature. It will, when you're printing the middle, the filament will like drop down. It will make you have like a perfect temperature. So whenever it drops, it, it should be solidified. Then it should be like printing the next layer top of it. So whenever it, it drops down, it should solidify. So you should maintain that kind of a temperature. And Jen. Okay. Yeah. The broken sample is like, that's what's been generated. Yeah, that the model is generated by myself. So it had some issues. Pretty good stuff was like, I downloaded from the model from the website. Yeah, this is the pretty good one. I downloaded from the website and this is the one. Yeah. Okay. Yeah, this is the new update. I think I should try this out. Yeah. So whenever, actually, yeah, need to try this out. I can do this all day. So whenever you're climbing from the hack, like climbing from the downstairs to upstairs, right? I can do this all day. Yeah. So, so I need to test it out. So next is testing the pura software and overhanging printing. So our printing. Okay. So GitHub links. So this is the doubling. If you want to know more about the four hand prints, you can go to the same. And this is also like cool YouTube video. We'll talk about our overhanging printing and they'll say like how to get the software part and how to do yourself if you want to build yourself. Okay. So live demo. Oh, okay. Again. Yeah. So, yeah, I think I'm there. So this is a pretty fast demo. So quickly I will show this is the website. So this website is really 3d website. So you can, you can, there is a lot of 3d printer stl files available online. You can choose a temperature or what kind of printer you have. You can do the settings, resetting. So here and get the stl file and the objects and you can really test it them. I actually I tested only one model. This model because our 3d printer hasn't had like the pretty good fan. So I have additionally added a plan and like made this model for especially to throw in the hackware talk. So this is the model which I thought to test it out with go with the smallest step like going to the bigger step and ending the failure is like, okay, it's a failure. But when you start with the smaller separate, eventually you know what the root cause of the things. So that's what I have did and I caused it. So this is a github page and it's like, I like this thing. Like it's rainbow effect, rainbow arcing. So rainbow arcing is nearly done by the software guy and the genius. Yeah. So this is right now it's in Cura. You can do it in Cura also. He printed many stuff. So when yeah, and you have the installation how to installation if you want. Yeah, if you want to build yourself, you can build it by yourself too. Okay, I think did I have. Okay. So I downloaded from the from the github. This is the documents we'll get. So you can, if you have like Python script like if you're good in Python or like, actually I was, I'm learning Python. So initially when I first trying to get the clone off from the git and try to execute in my Python, I was not able to get it. So I, I, what I did was I downloaded the condom on a condom, then on a condom as a huge library. If you want, if you just type what are the libraries you want, it will download everything for you. It's like easy matter. So, so that is the thing like I downloaded it and I'm running the software. So this is the program. It means yeah, it's printing the layers and you'll get the visualizations now. Okay. This is a cube. And if you want to print the cube in overhang, this is the art pattern between it initially is to start. And that is a rainbow. This is like this for, for action. And this is the G code pattern you require. So to make this, you need to actually change in the pie file, the main dot pie. So if you go to this file and you can see like pretty, maybe it's not so visible. So there's like this poly poly gone. This is that. Okay. I hate my platform. So you need to change these lines. When you, when you change this, I can't explain the code part of it. Maybe like, you're pretty good than me. So you can figure it out. Even I also figured it out in the way. So, so you can enable enable this part of the code lines and you'll be activated with the, with the pattern, the 2d pattern over here. This is the pattern you'll get it. And the next is next thing is you'll generate the, you'll generate the g code for it in the output file. So, then you'll get the g code of that layer particular layer particular high. Then what you need to do is you need to take this g code. And you need to go to your, your, your Kira, Kira software or like slicer, the software. So you, you, there you'll be generating the g codes. Probably you need to have like, over, over this, they use the rap title or some kind of a different software. So where you can visualize the g code. So you can remove the which part, which part has a support, you can remove that part and you can add this code to that. So we can just miss match and we can do the 3d printing. Yes, it's, it's cool hack, right. It saves plenty of time. Maybe like, maybe, maybe I should try the pure up cruiser part cruiser recently losing this kind of overhanging methods over are overhanging methods. So I need to try that and maybe the next hack where I would like to show them. Yeah. Hey, it's a good. Yeah. It came from the. No, no, no, no, it's it's came from the. Actually, the thing is like, you will, you will, you need to make the base line out of structure in Python. And you need to make only the base line automatically the arch will be generated by the rest of the code. This is developed. Awesome. And then you can. Actually, this is pretty scratch version of it right now. If they have updated the versions and if you are like interested and if you want to make some contribution to Prusa, this is the right time to make some contribution and make a hero name. I think I think I, I, I, I haven't explored that thickness, but it was like three five mm and five mm for the final one. Actually, 10 mm for that small piece that circular table, I think the fully like thing, which I give you that is 10 or 8 mm that was there. And for that, the high part, high part didn't come properly. I think your screen share is false. Oh, okay. You can just click with you. Yeah, yeah, you can go all the way. Okay, yeah, yeah, yeah. Yeah, okay. So, actually, I need to test that out thickness right actually go to like higher thickness also it's possible when I saw the video they were going like 30 40 mm. Oh, yeah, that's a great question. Maybe I think for this I need to go to the video but if you, if you're really interested you can have a look in the workshop where I physically I have attached the plan, but if you if I want to show to the viewers in the online and and if I want to show to the viewers in the online, so I need to show them the YouTube. Okay, this is not my YouTube channel, it's my YouTube channel but I have to go once. So, it's okay, yeah. Okay, and I'm ready. Okay, this part you see right this is the cooling part which you can see already. Both sides. Yeah, he's using the both ways. So, in my design I'm using one way. Actually, other way also there's a fan but it's not hidden the part it just pulls the extruder. So depending on the direction you're using the different. Actually, many people thought like, if you have a different kinds of movement, they can do a pretty good printing without supports, but that was ended in the failure but the software guy really supported. Yeah. Maybe great software for the software guy.
