Additive Manufacturing Applications II
10 am–Noon
Presentations, detailing case studies and research and
development activities, that continue to advance the
applications of additive manufacturing and 3D printing.
10–10:25 am
Case Study: Gas Ejector Nozzle Made
by Metal Laser Sintering
Shane Collins, Director, Business Development,
Oxford Performance Materials
Metal laser sintering (MLS), known by the trade names
DMLS and SLM, is used in demanding applications such as
surgical instruments, medical implants, jet turbine engines
and commercial aviation. Components made with MLS have
been shown by the University of Louisville and others to be
fully dense with limited porosity. This case study reports on the
use of MLS to develop a critical component for a gas ejector
nozzle requiring fine features, smooth surface finish and high
performance material properties. Through collaborative process
optimization, the challenge was met, and production-quality
nozzles were produced.
10:30–10:55 am
Metal Laser Sintering System Comparison, Product
Quality and Material Properties
Alex Fima, BS, President, Directed Manufacturing Inc.
Metal additive manufacturing, laser powder bed process, is
becoming an established technology for final part production in
diverse industries worldwide with applications from aerospace
to semiconductor. Directed Manufacturing will review the
capabilities of its current EOS and Renishaw metal laser
sintering equipment for production applications as well as
provide a material properties overview. Build speed, part quality,
cost of operations, including cover gas and consumables, and
overall productivity will be compared. Attendees will discover
the advantages of direct metal laser sintering (DMLS) and
selective laser melting (SLM) systems in a presentation that is
directly for anyone evaluating production capabilities of powder
bed metals process systems.
11–11:25 am
Conformal Cooling
Brandy Badami, Additive Manufacturing Account Manager,
Linear Mold & Engineering
Steve Spaleny, Director of Sales & Program Management,
Linear Mold & Engineering
By getting water into tight spots, we drastically improve part
quality. Using conventional methods you have to drill straight
water lines, and the intersection of two straight-drilled water
lines creates a low-turbulence area where sediment may build
up. With DMLS, Linear can design complex water lines that
eliminate these areas. Linear recently added Moldex 3D CAE
software with the FEA Interface, which can evaluate temperature
distribution. This provides in-depth injection molding simulation
to maximize the advantages of conformal cooling in the injection
molding process. The software will also be able to predict areas
in the mold that may incur hot spots, and can generate mold
bases with complex cooling channels automatically.
11:30–11:55 am
Metal Additive Manufacturing Goes Bigger
and Faster to Meet the Manufacturing Challenges
of Tomorrow!
Stefan Ritt, Export Sales and Marketing Manager,
SLM Solutions GmbH
Due to several requests from industry partners, a project got
started to design and produce a metal-AM machine which
incorporates the industrial requirements of build volume and
size and build speed and accuracy. This presentation will
highlight the demanding concept and design of a large volume
metal-AM machine operated by four high power multi-lasers
to achieve at least five times build speed compared with
today’s standard DMLS equipment to bring it much closer to
performance of existing production technologies. Reference
will be made to existing case studies and applications from
several industries and key players such as GE, Boeing, BMW,
Siemens and others. The audience will gain information
and knowledge of how to implement metal-AM not only into
high-profile and high-tech industries, but also for everyday
consumer items to bring back domestic workforce on top of
the latest technological and industrial standards into the US
and also take advantage of the benefits of powder-based
