3D printed 6-sided stamp

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.


Start by watching this tutorial and then spend some time practicing for yourself

Once you have completed your digital model, you need to using a “slicing” software to prepare it so that it can be read by the 3D printer. Watch this tutorial to learn how to do that:

Then the next step is to 3D print it! Once you have it printed, make sure and clean up any 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 the stamp:

It’s pretty self-explanatory, but here’s a short demo on using your 6-sided 3D printed stamp.
