 I will request Bhavin to present his talk. Okay, let me start. So, hi, I am Bhavin. So, I will be talking about a project I have been working on since March 2021 with my younger brother, who is a commerce student by the way. So, 3D printers. Something like I have seen in sci-fi movies. Not really, we are already there now. So, these are 3D printers on your desk. One example is Prusa i3, which is by Joseph Prusa. Another example is Creality Ender 3, or something like which we build from scratch. So, how do they work, right? You might be wondering if you have never seen one. Something like this. So, they basically build everything layer by layer. So, there are two techniques. One is FFM or FDM where the material is fused and put layer by layer on each other on top of it. Another is SLA, which is stereolithography, which basically done using liquid resin. But why build one, right? If you can get one. So, we thought it might be slightly cheaper to buy one. Another was freedom. So, this is the freedom in terms of modifying anything. Freedom as in free software, right? We talk about free software open source, that the freedom and the control you get with it. So, if you want to modify something, you can definitely do with the printer, which you have yourself built. So, the project RepRap, right? It stands for replicating rapid prototyper. The first RepRap printer was built by Adrien Boyer. And this is a community project, which actually started a revolution of this open source or open source hardware 3D printers. So, where is the Python involved, right? You might be wondering. So, there are a lot of projects, which are crucial in this ecosystem. Some examples, FreeCAD. It is a 3D modeling software. Printer phase is something which will run on your machine and give instructions to your printer. And there are slicing softwares, which actually convert your 3D model into some instructions for your printer. These are like Ultimaker cura or Octoprint or something. So, were we able to achieve it, build it? Yes, it was a success. We got the printer working. Some more images, if you are wondering, right? You want to see some more images. So, let me go through them. So, this is the design we did in the FreeCAD that is like to understand how it will look like. Next, this is the first frame, initial frame, which we came up with based on the design we had. So, you can see the printer is printing something right now. So, this is part of a 3D printer. So, you can see this kind of recursion or self-replication. A 3D printer cover for my UBT. 3D Benchy. This is like one of the popular models which people usually print using 3D printers. You might be wondering now, right? If I should buy one or build one. If you have time and you are interested in building something, if you want to take up the challenge, I would say go for it because it's slightly cheaper, one or two thousand rupees, but still it's worth it because you will learn a lot of things along the way. And if not, if you just want to print something and get started, I would suggest go with something like Reality Ender 3 or something. That would be your best choice. It will get you started immediately. So, if you want to read about the whole story, it is on my website, geeksocket.in. So, you can check that out and that's it. Thank you.
