So do I stick my head into that glass-enclosed rectangular box? Will it fry my brain? Or will the damage show up in 20 years? Will my head come out looking like those primitive shrunken heads that repelled and fascinated me as a child?
I’ve volunteered to have my head 3-D printed, and am checking out the equipment at the State University of New York. As it turns out—great relief—I don’t have to stick my head into the box after all; that’s where the “printing” occurs, not the scanning.
The professor tells me to just sit upright and stay super still on a chair for a little over a minute, while his assistant uses a hand-held scanner—making several passes of the sides and top of my head and neck from about 30 inches away.
In a couple minutes, the glass box starts to make noise and comes alive. The “printing” begins. For the color of my little sculpted head, I’m given a choice of red or white. Red seems a bit creepy, so I go for white. The plastic substance is long and cord-like, about 1/8 inch in diameter, and wrapped around a big spool at the back of the printer. One thin white layer after the other is laid down. It builds up, and slowly a tiny replica of my head begins to take shape. Half an hour, and it’s done.
Sure enough, this looks like a miniature Roxie, about 2 inches high, with a flat back where it lay down on the printer, although the machine appeared to have quit just before it reached the tip of my nose, which is kind of cut off.
So what can be done with this new kind of printing? Well, it is already being used in dentistry for making crowns. Jewelry can be created from metals, even gold. You can actually make plastic guns using this method. Unfortunately (or should I say fortunately), they don’t work very well—the plastic gets distorted rapidly from the heat and action of shooting a bullet.
But maybe the most fun is making food. Nursing homes in Germany are taking pureed food and making it into appetizing shapes. NASA is researching making 3-D pizza in space. Instead of white plastic maybe I should have asked for chocolate—and turned myself into a delicious dessert.
Roxie and her mini-me.

Using works from the National Gallery of Art by Vincent Van Gogh, Mary Cassatt, Edward Hopper, and others, Roxie Munro has created an innovative introduction to art. As an artist contemplates her next painting, she introduces genres and subjects, showcasing reproductions of great works. The sweeping painting she creates cleverly incorporates all 37 pieces she has considered.
Children can have fun finding the masterpieces in her painting and learn more about the artists in the notes in the back matter.
