  • I draw it and then I can hold it.
  • It builds up in tiny layers, over and over.
  • If it does not fit, I change it and print it again.

You can love 3D printers in Alpharetta.

What it really is

A 3D printer builds an object one thin layer at a time.

Three things to try today

  1. Draw a part you wish existed.
  2. Measure something it has to fit.
  3. Write down the measurement to the millimeter.

For the grown-up reading this

Alpharetta has a population of about 62,298. Somewhere in that number is a kid who lights up about 3D printers and has never met another one.

Tolerance is the lesson. A part that is a millimeter off does not fit, and that is the point.

If the kid who loves this is a girl
