Come gather 'round, my little friends,
Let me tell you a tale that never ends.
Of models, rafts, and printers too,
And the magic they can do.

A printer whirs and hums along,
As it creates a model strong.
Using monomers, mesh, and more,
A world of wonders we explore.

But what's this? An overhang we see,
How can it print so perfectly?
A motor roars, the raft it grips,
Ensuring our model never slips.

So let us marvel at this machine,
And all the things it can convene.
For with a printer and some glue,
We can make dreams come true.

Reflections

1. What is 3D printing and how does it work?
2. What are some of the materials that are used in 3D printing, and what do they do?
3. How does a 3D printer create a model that has an overhang, and what is a raft used for?
4. Why is a motor important in 3D printing?
5. What are some of the things that you could create using a 3D printer?
