PAST Foundation provides teachers with a process
to deliver meaningful STEM education.
“Meaningful” differs for every learner and every
teacher. The PAST designed toolkit and Knowledge
Capture program enables entire communities to
transform traditional classrooms and reach every
learner. The results are engaged
students, empowered teachers, and a community
actively involved in student success.
My work at PAST focuses on
Knowledge Capture: Understanding You
PAST ethnographers use a set of methods that
identify issues, success, and constraints to help steer
policy and drive successful transformation.

What is 3D printing?
• Adding material layer by layer to build a
• Different from subtractive manufacturing
(mill, lathe, CNC routing) by adding material
instead of taking it away.
• Plastic, powder, metal and other polymers.
• Classroom models include ABS (think
McDonalds toys) and PLA plastic.

Why 3D printing will change the world
• Current injection molding requires costly and
time consuming mold creation.
• 3D printing allows for faster prototyping so a
mold is only made once.

So how is this useful for me?
Application of Knowledge
• 3D printing and CNC machines applies
geometry, trigonometry, design thinking and
• School projects can take a lot of time, supplies and
expertise to build.
• 3D printing allows for faster design cycle
iterations, therefore more modifications.
• Students can try ideas out instead of teacher guiding
toward “correct” answer and method.
• Ideo shopping cart is great example of design work:
• Use the 3D printer to produce final products
for student projects.
Tools and Starting Points
Where should I begin?

comes with the 3D
Settings like fill ratio
• 3D printer
• Site for sharing .STL files.
• Other people have created many things you
can just print!
• An online minecraft server that allows you to
export .STL files from objects you build while
playing a video game.
• Extremely simple CAD program suitable for
• Drag and drop functionality to create .STL
• Robust professional tool suitable for high
