In this unit, students will create a 3D digital model of a 6-sided stamp in the 3D modeling software TinkerCad. Once the model is created, the student will learn to export the model as an .STL file, then import that model into Cura, a 3D printing program that “slices” the model. Once the digital model is in Cura, the student will learn to prepare the model for 3D printing and export it as a .GCODE model.
What you will learn:
– How to use the “scribble”, “text, and “shapes” tools to create both positive and negative impressions on a digital form
– How to “group” and “ungroup” forms using Tinkercad
– How to “mirror” and “flip” 3D text using Tinkercad
– How to scale, rotate, and position shapes within 3D models
– How to prepare a digital model for 3D printing
– How to use your 3D printed stamp to create new textures and surfaces on your work.
If you have not watched and completed the exercises in the Tinkercad tutorial HERE, you should start by doing that. The techniques presented in the following video rely on you having a basic understanding of Tinkercad (as presented in that tutorial).
If you have already watched the Tinkercad tutorial and practiced using the tools on your own, then watch the tutorial below that is specific to making a 6-sided stamp.
Now, it’s time to practice! Keep in mind that you don’t need to complete your stamp on the first try – experiment with several shapes and configurations before you settle on one you like.
Here is the digital model from the video:
Once you have completed your digital model, you need to use a “slicing” software to prepare it so that it can be read by the 3D printer. You will now use the slicing software called “Cura”. It is available for free and can be downloaded HERE. Watch this tutorial to learn how to prepare your stamp model for 3D printing:
Now that you have your model sliced and the GCODE is created, the next step is to 3D print it!
Once you have it printed, make sure and clean up any of the temporary support that printed with the object. It’s usually best to use a small, sharp Xacto knife (Carefully!). You might also need some fine sandpaper to clean up any burrs or rough spots.
Here’s a short demo on how to use your stamp:
