PRINT YOUR FUTURE

wood with a CNC router, a high-tech
cutting machine.
West Valley students must understand
3D printing before entering the district's
two-year Boeing Core Plus curriculum
in high school. From there, students can
advance to the Boeing manufacturing
program and, potentially, an apprenticeship with the aircraft company.
The curriculum allows students to
meet graduation requirements while
earning manufacturing skills they will
need to enter the workforce.
Nesmith offers pointers for other edu-

cators: The next generation of the workforce will also need to understand the
software and computer language used by
these printers. Even as the printers evolve,
the basic concepts will remain the same.
Schools should also ensure their 3D
printing technology matches what is used
in student internships or apprenticeships.
In South Carolina, students in Robert Molkenthin's computer-aided design
and drafting classes at the Aiken County
Career & Technology Center already
use their skills in the real world. A local
orthodontist guides the class in printing

Cutting-edge curriculum
Some examples of how educators use 3D printing in various subjects
Computer-aided design and drafting
An orthodontist guided students in
printing models of patients' mouths
and gums to determine where to
place implants.

Fashion & fire-training
Students in South Carolina printed
sandal prototypes while another
class created parts to fix a fire
truck's emergency lights.

CTE
As a precursor to high school
aeronautics, middle school students
in Washington printed model cars for
aerodynamics testing.

Math
One teacher says 3D printing is
not possible without a thorough
understanding of graphing on the
x- and y-axes.

Neuroscience
Students attached electrodes to their arms to control a "grabbing claw" that
picks up items with a cloth-covering. They printed different-size cloths of
various texture to determine the best grabber.
ELA
Inspired by a children's book,
elementary school students
3D-printed canoes and cast them off
in a nearby river. The canoes have
QR codes so they can be logged on a
school website when they are found.

3D models of patients' mouths and gums
to determine where to place implants.
The class also works with the county
health department to create prosthetics.
Elsewhere at the school, students
studying fashion have printed sandal
prototypes while students in the school's
fire-training program manufactured new
parts to fix a broken siren light on a
donated fire truck.
"The first attempt was off by 5/1000th
of an inch, so the light wouldn't turn," he
says. "Thanks to the 3D printer, they were
able to press on, make another model and
it worked."
That is the main lesson for students:
"Take something that doesn't work,
tweak it and watch the product work,"
Molkenthin says.
Learning without realizing it
3D printers create STEM lessons naturally, says Michael Roland, technology
instructor at the Public Schools of Calumet-Laurium-Keweenaw on Michigan's
Upper Peninsula.
The printer must be told what to create, and that is done by plotting lines on a
graph. "You can't do 3D printing without
talking about the x- and y-axes," he says.
Roland's classes use the printers for
engineering lessons, such as bridge-building competitions in which students learn
from each mistake as they re-plot their
structures. He also lets students design
their own products, because when a student hatches an idea, they will go to great
lengths-and through lots of calculations-to see complete it, he says.
And suddenly, math isn't some
abstract concept that students think
they will never use in real life. With 3D
printing, students learn-and prepare for
future careers-without even realizing it.
One student, for example, made
an innovative pencil holder, but never
thought to measure the pencil beforehand
and it didn't fit, Nesmith says. "When
you look at something on a computer,
you can't see what it is going to look like
