There are people who are developing
large-scale 3D printers that can print

With all the possibilities, Harper

including art, math, informatics, and
engineering. It provides a unique

certainly, without any
question” believes the
technology has a place in
various subjects. In fact,
he spoke with Harper
about the ability to
use 3D printing in
calculus courses.
The 3D printers open up the
possibility of creating 3D models
that might help students understand
how to apply calculus to discover the
volume of an object, for example,”
Lang said. 
When a student in an upper-level
calculus class is tasked with finding
the volume of an object, textbooks only
provide a two-dimensional rendering.
A 3D model would provide students
with a tactile representation of the
object and could help learners who
respond more to visual rather
than analytical learning.
While Lang is primarily
interested in using the
technology in his math
courses, he also has great
respect for Harper’s use
of the technique in The
Open Crowd Project.
It’s a really great idea,
and it has been executed
beautifully,” Lang said.
You look at these models
and you can truly recognize the people.
It really is impressive.”
From an artist’s perspective, The Open
Crowd Project is a new way to connect
people, Harper said. It reinforces a
sense of togetherness between people
who may otherwise be strangers and
adds a new layer to how the world
Part of the responsibility of an artist is
to help interpret the world around us,”
