Other researchers are developing computer algorithms that can skillfully stitch
together scanned cross sections of a faulty organ into a single 3D computer
model. A major challenge continues to be how to best manage the enormous
reams of data generated by the medical imaging process.
In the larger computing industry, commercial video game designers are
making strides capturing surface details and better understanding how to
graphically depict the way our bodies move. The medical establishment is
making progress in capturing more precise digital details about the insides of
our bodies. Academic scientists are building ever-more powerful algorithms
to model, predict, and analyze data collected from biological systems.
Real bioprinting—designing and editing living tissue and body parts—
won't become a reality until there's truly usable CAD for the body. Medical
imaging, as powerful as it can be, can only generate a design ile from a body
part that already exists. There's no software that can enable even a skilled
medical professional to design an entirely new heart from scratch or even
edit an existing one.
The problem with the human body is that it's irregularly shaped. Our bod-
ies are miracles of geometric complexity. Each of us has our own unique body
shape with lots of surface curves, different cell types and millions of minute
details. Delving deeper, under the body's skin lies a biological wonderland
whose complexities rival those of the galaxy, rife with mysteries.
Bodies change constantly. They're moody, prone to ever-changing states
of constant lux in response to changes in our environment, our emotions
and what we eat. Millions of cells grow, heal, and change on a daily basis in
mysterious ways we don't yet fully understand. Cells signal to one another in
ways that we have yet to decode.
Advances in traditional design software, medical imaging and data analysis
will pave the way for 3D printing replacement parts for living creatures. But will
we soon see commercial design software for body parts? Not yet. But we're inch-
ing closer every year. “I'm seeing a convergence between the world of simulation
software, medical imaging, and CAD systems.” Chris joked, “It will personalize
medicine for us, which is good if you plan to need extra body parts in the future.”
In industrial product design, designers are learning that as their design
tools improve, nature becomes an increasingly useful source of inspiration. In
body design, it will be the same. Living creatures are the product of millions of
years of ruthless, iterative design cycles. Janine Benyus, an author and design
visionary, said, “We've discovered again and again that biomimicry works
