So that, without worrying about designing the files, you can right away start printing without any hassle. ![]() These websites host a huge collection of 3D printable files which can download either by paying for it or simply for free. One of the most popular 3D printing repositories is Thingiverse. If you are someone who has little knowledge about 3D printing, you probably know about 3D printing repositories. To make the task easier, we have come up with some of the most popular 3D printed mechanical toy designs that your younger ones would love to play with. All you need to do is find the design on online repositories and print the one you like. Wait! Are you not sure how to design one for yourself? That is not tricky at all. So, why not let our kids witness the best side of additive manufacturing by designing 3D printed mechanical toys. While we celebrate the success of the technology, the kids just fascinate about creating unique toys with these amazing machines. From home users to industries, everyone is excited to include 3D printers for some of the other operations. EJW 3D-printed clock.zip includes Autodesk Inventor files and solid model exports (stl and sat files).Being the state-of-the-art technology, 3D printing has something for everyone. I've included the complete CAD files from the escapement shown here, so you can use my models as a starting point for your own creations. Obviously, nice escapements and clocks can be built by hand, and I encourage anyone mechanically-minded to at least visualize how escapement works, if not trying to build one yourself. The bed size of the Statasys (about a cubic foot) prevented me from building much larger versions of this escapement where the tolerances wouldn't be as much of an issue. The weight, which is out of the video frame, is connected to a spool on the center of the escapement wheel via a white string that is almost in visible in the video. In the video, I have quite a large weight pulling on the escapement wheel and the pendulum moving briskly, but if the pendulum loses just a little bit of energy and doesn't make a full swing the escapement wheel doesn't lock, and instead, spins freely dropping the weight. While it did work, the tolerances on the one shown were not quite good enough for it to work consistently. The escapement proved to be the biggest challenge. I printed working gears, springs, and escapements in my attempts to test out each of the required components. I imagined that after dissolving away the sacrificial material, you could wind the clock up and have it start ticking. I was big on clocks, and was trying to design a fully 3D-printable clock. This project dates to 2001 when I was at the MIT Media Lab. With careful design, you can create captured moving parts, like the interlocking gears shown in the Slideshow. The hot noodles are printed layer-by-layer and fuse together building finished-quality-level parts. The Stratasys FDM works by laying down "hot noddles" of ABS plastic and a sacrificial material that can be dissolved by water. These are the basic components of a clock 3D-printed by a Stratasys FDM 2000. ![]()
