Hint: it's not magic.
Watch this video for a quick rundown on what is actually happening when something is 3D printed. |

Just like a regular printer at school, you start with a file that you wish to print. In many cases as school, we're printing a Google Document or an Image File. Each of those have its own file type (i.e.: .pdf, .jpg, .doc). While there are a few different file types for 3D models, the most common - and the one we utilize at school - is an .STL. But how do you design an STL?
In order to design an STL file, you need a special type of software called a CAD software. CAD stands for Computer Aided Design. There are many different CAD software available, but a great starting point is TinkerCAD. It's a free software and it works on Chromebooks. You also don't have to download any software which is great. Watch this video to learn how to create an account on TinkerCAD.com. |

This video overviews the basics of using the TinkerCAD software. In this video, I demonstrate how to combine geometric shapes to create a custom Nintendo Switch cartridge holder.

Once you have your design finished and you're ready to print, you'll need to get the file to me so I can prepare it for our 3D printer. I use a tool called a slicer to convert your .STL file into gcode. Essentially, this program turns your file into hundreds (or thousands, depending on how big your design is) individual slices. This is how the 3D printer knows where to go and lay filament.
The first thing you'll need to do is make your TinkerCAD design public (by default it is set to private). Once you make your design public, you will have a link that you can share. Watch the video to see how to make your design public and get the public link. |
Once you have the link, you'll need to complete the 3D Printer Submission Form. Answer a few quick questions and enter the link to your design.
