• 70+ AM devices cleared through the 510(k) pathway
• AM devices regulated through the same pathways as non-‐AM devices
• Significant increase in 510(k) cleared devices 2011-‐2012
• Majority of 510(k) clearances for orthopedics applicaMons

Common Applications
#DWwebinar
Medical Devices are Regulated J
Any 3D Printed Medical Device has to go through same ‘scope of a regulated product’ as non 3D printed medical devices.
(even 3D printed ones) Receipt of materials
Design of product
Premarket testing and
activities
Manufactu-ring of
product
Final inspection/
QC of product
Shipment of product

What were some challenges you’ve encountered in using 3D prinMng in
a medical applicaMon?
#DWwebinar
Its not just about the 3D printer anymore…
The Digital Thread
#DWwebinar
We Had to Rethink Design
• Patient specific design is complex • Software tools made to handle organic geometries are key
#DWwebinar
Haptic Design
#DWwebinar
Conformal Design
#DWwebinar
Consistency in Manufacturing • Raw material control • Calibration • Environmental controls
(temperature, humidity)
• Part support • Post Processing
(removal of liquid polymer / excess powder, light curing, stress relief / HIP for metals)
#DWwebinar
Build Orientation of Parts
#DWwebinar
Why additive for implants? • Porous, porous, porous • Bone ingrowth provides both
better initial and long-term stability
• Properties close to human bone (avoid stress shielding)
• With additive methods we create the solid and porous in one integrated step
• Complexity is free • Ideally suited for patient specific

Unit Cells of Design • Design Strongly effects
performance • Density: overall porosity,
pore size, strut size • Design is based on unit
cell size and shape
#DWwebinar
With 3D printing, how will design of medical devices change?
• THINK DIFFERENTLY – you are no longer designing based on the confines of a traditional manufacturing
• Conformal design for the human body will continue to grow
• The design cycle from idea to product continues to improve Swedish firm Gassling

Hip stem implant Manufactured on M2 cusing / prototype manufactured from the material CL 41TI (TiAl6V4 ELI) / LaserCUSING allows the manufacture of implants with unique geometric features, which in turn make new features or functional integration in implants possible. These include macroporous surface structures for an improved bone ingrowth into the implant and volume structures to adopt the stiffness of the implant to the bone. Implant with metal bone „foam“ • Lattice structure to allow bone ingrowth • Only possible with additive technology • Mass production or customized products
