2D & 3D Modeling on
What is
Laser Cutting?
Imagine a super powerful light, like a laser pointer, but much stronger!
It can cut, draw, or make designs on different materials like wood, metal, plastic, and fabric.
The laser follows a picture or design that someone made on a computer.

What is
3D Printing?
Imagine if you could draw something on the computer and then a machine turns your drawing into a real object you can hold!
That’s what 3D printing does by adding material, like plastic or metal, layer by layer, kind of like building with tiny blocks.

You can download vector files from websites like MakerCase
You can create your own vector files from CAD software like TinkerCAD
To 2D or 3D Model
In order to laser cut or 3D print, you first need to design digitally
Today we will use TinkerCAD
Agenda
Learn about TinkerCAD
Make an account and use the slides to start playing around with it
Start 3D Modeling
Sketch what you designed by deconstructing the shapes
Create a new file on TinkerCad to represent your deconstructed model (2D)
Compare your 3D model with your 2D file

Click on "Create your first 3D design"
choose a cube to start
change it's size!
add more shapes if you want!
4
Bring your model to paper by sketching what you designed on TinkerCAD (keep it 3D)
Now try to deconstruct each shape into a flat surface.
Use the next slides to help you do that!
SKETCH YOUR DESIGN
Using paper and a pencil, sketch the faces of the shapes you modeled on TinkerCAD.
Think about how they fold onto each other to become the 3D shape
How do you think they will connect?
What shape do you think this is to the right?

CREATING 2D DESIGNS IN TINKERCAD
Create a new file on TinkerCad to represent your deconstructed model (2D File)
Click on Top View and add all the faces of each shape of your model

Click TOP to look straight down at the workplane because we will be designing for 2D cutting
Click Flat View
to look straight down at the workplane also
Click Export
when you are done designing and select SVG as your file type to laser cut

Remember
to set your lines to the material settings for what you are cutting
Remember
to turn on the air filter before you start your cut
ENJOY LASER CUTTING!
