used in both configurations. Comparisons of weight, cost, and
flight performance were performed, and this work describes the
findings in each area.
Medical and Dental Applications
10 am–5 pm
Medical applications including dental continue to grow in use
and scope. These include, but are not limited to, prototyping,
bio-modeling/anatomical modeling and direct production of
implantable metal implants or scaffolds for tissue engineering.

Medicine Meeting AM Technology:
Close Encounters of the Third Kind?
Jules Poukens, Professor, MD, DMD, PhD,
University Hasselt Belgium
CAD/CAM and Additive Manufacturing (AM) are getting more
attention in the medical sector, especially in cranio-maxillofacial
surgery where defects of the face (e.g., absence of a nose, ear,
or eye) have an important psycho-social impact. Radiological,
optical, or laser scans of the patient are converted into a virtual
three-dimensional patient with subsequent virtual design of a
medical device or implant. AM methods enable the production
of custom implants and prosthesis in a solid or resorbable
material, or even in multiple materials. The introduction of AM
and related technologies in medicine are a breakthrough in the
treatment of very complex patient cases that were previously
untreatable. What’s more, they are reducing operating time
and patient discomfort. This progress is serving as a “stepping
stone” to the 3D printing of organs in the future in order to
improve life quality of the patient. Introduction of engineering in
medicine looks as a small step for an engineer, but represents a
giant leap in medical history.

Direct Comparison of DMLS and
EBM Ti6Al4V Performance in Vivo
Emanuele Magalini, R&D Manager, Eurocoating s.p.a.
Additive Manufacturing (AM) techniques, such as EBM and
DMLS, using Ti6Al4V powder, are suitable to produce implants
with porous surfaces named “trabecular-like” structures.
Solid part and trabecular surface are produced in the same
manufacturing step. The importance of mimicking human
trabecular structure on implant surfaces is confirmed by
investigations that showed a substantial increase in implant
fixation strength when highly complex networks are used.
Our contribution to this thesis comes through in vivo tests done
in goat model. The same trabecular structure was manufactured
using either EBM or DMLS. Specimens with different pores
and struts sizes were obtained, due to dissimilar resolution
limits existing for the two techniques. Explanations occurred at
four weeks after surgery for one group and at 15 weeks for the
second group. Each goat received EBM and DMLS specimens for
mechanical and histological analysis.

Additive Manufacturing for Surgical Implants:
It’s the Present and the Future
Andy Christensen, President, Medical Modeling Inc.
In the last decade since Electron Beam Melting (EBM) was
introduced it has been applied to produce real-world production
parts in the aerospace and medical device fields. In the
medical device field, EBM has been used to displace traditional
manufacturing techniques for existing products as well as enabling
production of completely new products not otherwise possible to
produce. These unique opportunities to provide value and enable
novel devices are where much of the focus will continue to be
placed. This talk will focus on how additive manufacturing is
being used today for production of implantable medical devices in
addition to where the presenter feels the market will continue to
grow over the coming years for these technologies.

Using Additive Manufacturing to Produce Custom
Prosthetic Attachments for Wounded Warriors
Peter Liacouras, PhD, Director of Service, 3D Medical
Applications Center, Walter Reed National Military Medical
Center Bethesda
Kevin Wurth, Director of Operations, 3D Medical Applications
Center, Walter Reed National Military Medical Center Bethesda
The technology in the design and function of the prosthetics the
military uses to restore function and mobility to our wounded
warriors is highly advanced and unique. These typically young
