Yu Jiang Tham has been sharing a series of tutorials for how to build your own 3D printed drink mixing robot. Here’s the 3D printing stage of the build.
I built a robot that mixes drinks named Bar Mixvah. It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the frontend and backend. In this post, I’ll teach you how I made it. You can follow along and build one just like it! I’ve also put the 3d model (blender), stl files, and the code up on GitHub for you guys to download.

- Part 2: Software Design
- Part 3: Operation, Caveats, and Further Modifications
First, a little bit more about the robot. The entire thing costs approximately $180 to make. All of the parts are 3d printed, so you’ll need a 3d printer to build this. I used the MakerBot Replicator 2X, but any 3d printer should do. Total time to print the pieces is about 18 hours, depending on your settings, and assembly wiring….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
