30 YEARS OF INNOVATION
Our founder and Chief Technology Officer, Chuck Hull, pioneered 3D printing with the
invention of Stereolithography 30 years ago, and we’ve been innovating ever since.
Chuck Hull accepts National Inventors Hall of Fame
Award -- 2014
First 3D printed part – 1983
WIDE 3DP TECH RANGE:
• Stereolithography (SLA)
• Selective Laser Sintering (SLS)
• ColorJet Printing (CJP)
• MultiJet Printing (MJP)
• Direct Metal Printing (DMP)
• Film Transfer Imaging (FTI)
• PlasticJet Printing (PJP)
R&D capacity constantly innovating, to
deliver new commercial products – where
there are/will be markets.

HOW COMPLEX IS THIS INDUSTRY– 3DP IS NOT A MONOLITH.
Manufacturability? Repeatability? Resolution?

A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the [art of] 3D
printing that has the potential to revolutionize the way we make almost everything.

An Open, Layered Protocol for Powder Bed
Fusion Additive Manufacturing (PBFAM)No standard protocol currently exits specifying the behavior of, monitoring, or control PBAM systems
To develop and demonstrate an open, layered protocol for powder bed fusion additive manufacturing (PBFAM)
OPEN PARAMATERSCustomizing to OEM Customers: Continuous Innovation
AM-Designed, Produced Heat Exchanger
• Demonstrate the use of laser powder bed fusion additive
manufacturing (AM) processes for fabricating metallic heat
exchangers for propulsion applications, to include the
design, inspection, and evaluation of performance.
• Conceive, build, and validate a novel, highly advanced
propulsion product, leveraging its resources and vast
experience in heat exchanger design and laser Powder Bed
Fusion Additive Manufacturing.
• Focuses on developing a heat exchanger that best
addresses thermal fatigue, envelope optimization, pressure
drop, flow distribution, and thermal performance and
producing designs that feature high thermodynamic
efficiency, including thin-walled highly complex structures.
Stereolithography Production Series
Casting patterns, molds,
end-use parts and
functional prototypes
• Develop/produce products without cost/time of
CNC machining / injection molding
• Reduce per unit cost on low- to medium sized runs
• Best surface finish of any 3D printer
• Large, whole parts. cut time for assembly
• Streamline path form CAD or scan to final prod.
Curing a photo-reactive resin with a UV laser
Selective Laser Sintering Production Series
Tough End Use Parts
• Manufacture volumes of durable 3D
mechanical properties suitable for end use and
tough prototyping applications
• Reduce production/logistics due to no tooling
• No supports required with SLS
• Broad SLS material range
Heating/fusing powdered polymer via laser
DIRECT METAL PRINTING: Distinctive Features
(1) Patented powder layering system
(2) Enhanced Imaging system & software
(3) Integrated “hands off” powder handling
316L 1.2709
Unlike any other system: Metal wiper lays powder bed on the build plate and a special
roller compacts the metal powder to the desired layer thickness/ density on return.
Other systems suffer from inconsistency from one layer to the next.
With this system, fully functional metal parts are directly produced.
� Parts from one batch to the next are sintered with consistency and quality
� Smaller metal powder grain size when extreme detail is needed
� Works successfully with spherical and non-spherical powder particles
� Works with metal and ceramics in same equipment
PATENTED POWDER LAYERING SYSTEM
Hands Off Powder Handling
• Avoids powder contamination
• Automated powder handling
(closed build chamber)
• Good atmosphere control
• Safe handling of reactive
materials
Greatest Tolerances & Repeatability
• High precision first time build tolerances on most dimensions
• Better tolerances for repeat builds that can be dialed in
• Unparalleled Repeatability in all 3 axes (key for manufacturing)
