Another groundbreaking use of 3D printing
for implants was carried out in a procedure
by the University Medical Center of Utrecht
in the Netherlands in which surgeons used
an entirely 3D-printed implant in replacing a
woman’s skull ( www.mdtmag.com/july1462).
Compared to old methods that used a type of
cement, this new method allows for a better fit
and patient specificity.
The University of Southampton has further
proven the importance of patient specific
devices through the successful surgery of a
3D-printed hip implant ( www.mdtmag.
com/july1463). The implant is made up
of a graft of bone scaffold and stem cells
from bone marrow. The grafted scaffoldings allow for blood to flow through,
ultimately making new bone growth
An exciting procedure was recently
conducted by the Centre for Applied
Reconstructive Technologies in Surgery
( www.mdtmag.com/july1464) in their attempt
to reconstruct a man’s face. A 3D-printed mod-
el was produced before the procedure and used
in practice for cut guides. This indirect use
of 3D printing for models shows some of the
greatest potential, since the method is quick,
efficient, and readily adjustable in designing for
a patient’s specific anatomy.
OxSyBio ( www.mdtmag.com/july1465) is
in the process of exploring 3D printing for
creating synthetic tissues, through the use
of a method developed by Gabriel Villar, an
engineer at Cambridge Consultants. The technology is highly sophisticated, as the material
involves the use of small water droplets held
together by thin films that mimic cell membranes. Certain proteins can even be used that
allow the droplets to communicate among
each other in much the same way that cells
communicate in living tissue.
“This technology might be developed to cre-

ate on-demand replacements for living tissue,”
says Villar. “Because it is possible to control the
contents of each droplet in the printed materi-
al, the geometry and chemistry of the material
can be tailored in each case. A longer-term
goal is to print a functional replacement for an
A different approach to synthetic tissues
involving 3D printing technology is the BioPen
( www.mdtmag.com/july1466). The Univer-
sity of Wollongong team in Australia have
created this unique tool that allows orthopedic
surgeons to distribute live cells onto injury sites
toward the regeneration of tissue. The BioPen
is currently in clinical trials.
The potential benefits of 3D printing for
medical design engineers are great. 3D printing offers significant cost-efficiency, as well
as versatility. The speed with which designs
can be 3D printed also opens many doors.
Most importantly, the inherent patient-cus-tomizability of 3D printing means that
products can be designed to perfectly suit
each individual. This capability alone could
The BioPen, created
by a team from the University of Wollongong,
enables orthopedic surgeons to “draw in” live
cells onto injury sites in
order to encourage the
regeneration of tissue.
