3D PRINTING IN THE MEDICAL FIELDA COMPREHENSIVE LOOK AT ADDITIVE MANUFACTURING’S CONTRIBUTION TO MEDICINE.
• Personal Introduction and Background• Overview of Custom Orthopaedic Solutions and its mission• Additive manufacturing applications in medicine • What to look for in 3D printing technologies• Future of additive manufacturing in medicine• Q&A
BACKGROUND• Graduated Ohio Northern University 2002
• Advanced Manufacturing and Virtual Simulation• 14 years in 3D printing
• 12 years in service bureau industry• Worked at companies in Ohio, California and
Oklahoma.• First exposed to medical printing in 2004• Joined Custom Orthopaedic Solutions February
2014
FIRST EXPOSURE TO MEDICAL PRINTING• 2004, created cranial facial implants.
• CAD models from CT Scan• Generated on SGI O2 computer.• 3D printed skull model as template• Implant mocked up and cast in PMMA
• $300 on Ebay
CUSTOM ORTHOPAEDIC SOLUTIONS• Specialize in preoperative planning solutions for
orthopedic surgeons.• Company formed in 2011, result of Ohio Third Frontier• First product launch in 2015 for shoulder arthroplasty
• Use a combination of software and 3D printing to plan implant placement and achieve planned trajectory
• Proper implant placement can lend itself to optimal range of motion, improved implant life, and secure anchoring of implant
• Shoulder software and web portal being used by physicians in ongoing shoulder studies
• Currently being distributed by Arthrex
3D SMARTBONE
• Generated from patient CT scan
• Landmark coordinate system established
• Implant trajectory established by technician and approved by physician
• 3D Smartbone assembled from approved trajectory
SCAPULA COORDINATE SYSTEM
(FRIEDMAN’S LINE)
COS WEB PORTAL• Preoperative plan
uploaded to web portal for physician approval
• Physician can make adjustments and change implant size/type.
• Approved plan received into COS software for SmartBone assembly.
3D PRINTED SMARTBONE
INTELLIGENT REUSABLE
INSTRUMENT (IRI) CAPTURING FORM OF
SMARTBONE
IRI TRANSFERRED TO PATIENT, SMARTBONE
PIN TRAJECTORY DUPLICATED
INTELLIGENT REUSABLE INSTRUMENT (IRI) USED IN SURGERY
5D SMARTBASE DEVELOPED AS AN ALTERNATIVE TO 3D PRINTED SMARTBONE.
DEVELOPMENT OF 5D SMARTBASE
A.M. APPLICATIONS IN MEDICINEPUBLIC PERCEPTION
• “Like in Grey’s Anatomy?”• Many examples featured on the show
were based on real life cases
A.M. APPLICATIONS IN MEDICINE • 54 year old man with tumors
invading the sternum and ribs• Removal of the tumors would leave
unprotected heart and lungs• Solution: custom 3D printed
stainless steel replacement sternum and ribs
• Designed and printed in Melbourne, Australia
• Surgery performed in Spain• Patient discharged 12 days after
surgery
A.M. APPLICATIONS IN MEDICINE 3 AREAS WHERE A.M. HAS CONTRIBUTED• Medical Models
• 3D representations of patient specific anatomy • Used in surgical planning and research
• Prosthetics• Low cost custom sized components• Flexibility in design and creativity
• Implants• Patient specific for custom fit• Ability to treat conditions not supported by available
implants
A.M. APPLICATIONS IN MEDICINE
Custom Prosthetic Limb Medical Model of Human Heart
WHAT TO LOOK FOR IN 3D PRINTING TECHNOLOGIES
• Materials – How does it need to perform?• Heat Deflection • Rigidity• Surface finish• Aesthetics• Chemical resistance• Biocompatibility
APPLICATION IS EVERYTHING
WHAT TO LOOK FOR IN 3D PRINTING TECHNOLOGIES
• Build Process – What techniques will achieve desired result?• Build resolution• Surface finish• Multiple materials
• Post processing procedures• Support removal• Part smoothing
APPLICATION IS EVERYTHING
WHAT TO LOOK FOR IN 3D PRINTING TECHNOLOGIES
• Cost of Ownership – How much?• Capitol Expense• Material Costs• Ongoing Maintenance• On-sight expertise and labor
APPLICATION IS EVERYTHING

FUTURE OF A.M. IN MEDICINE • 3D printed biologics
• Implantable tissues and organs with decreased risk of rejection.• 60% of solid organ transplants in 2012 were kidneys• Currently over 100,000 people awaiting kidney
transplants www.kidney.org• Absorbable 3D printed scaffolding for use in tissue
repair and bone growth• 3D printed pharmaceuticals
• Low volume production runs and personalized medicine• Produce a wide range of APIs (Active Pharmaceutical
Ingredients) on demand for use in medicine R&D.
Q&A?• Will hospitals and physicians 3D print their
own solutions for patient care?• Unlikely given current regulatory guidelines
