Can 3D Printing Lower Health Expenditures and Improve Patient Outcomes?
Morris J
Department of Radiology, Mayo Clinic, USA HOSPITAL AUTHORITY CONVENTION 2017
The Mayo Clinic has been able to improve the lives of patients while lowering health expenditures through the use of 3D
printing. In the USA, as in most countries, private and governmental healthcare insurers do not reimburse 3D printing of
anatomic models from radiographic data. This has led to a barrier to entry in most hospital systems and private companies
despite early evidence in outcomes and cost savings across multiple disciplines. In this presentation, we will outline the
cost savings that have occurred while improving care through several clinical scenarios. We will discuss the “Big Picture”
approach to funding hospital 3D printing laboratory. The audience will learn cost saving realised in craniomaxillofacial surgical
cases by in-house 3D printing of custom osteotomy guides and complex anatomic models. In the field of thoracic surgery
we will demonstrate cost saving through less invasive approaches to pancoast tumour resections pioneered due to the
understanding of complex anatomic relationships not otherwise possible without patient specific life size 3D printing. Cost
benefits of minimally invasive patient specific simulation through 3D printed complex aortic aneurysms will also be discussed.
3D printing at Mayo Clinic has allowed us to advance medical education, surgical care, patient education and reduce overall
cost in certain surgical settings.

Medical 3D Printing: Opportunities and Challenges Ahead
McMenamin P
Centre for Human Anatomy Education, Monash University, Australia

The 3D printing (or additive manufacturing) revolution is often promoted as one of the most significant modern technological
advances with impact way beyond its origins in computer-aided design and manufacturing where it helped engineers design
and print prototype devices or parts without the need for conventional manufacture-modify-remanufacture paradigm. Whilst
the technology has been heralded as having all sorts of impacts in medicine the evidence of its utility in medical education,
surgical planning, procedure guidance, and simulation whilst beginning to emerge is in its very early days.
The apprenticeship model of surgical education has transformed over the decades, and although the extensive operative Wednesday, 17 May
caseload of surgical trainees is the keystone to their training, surgical simulation plays a substantial role in their primary and
continued education - including development of novel surgical techniques. The significance of simulators within neurosurgical
primary and continuing training for example is reinforced by the central role they hold in courses and special groups
organised by the Society of Neurological Surgeons and Congress of Neurological Surgeons. A consistent theme in the
literature is the failure of most surgery training simulators to replicate the entire surgical approach and the lack of appropriate
anatomical, visual and haptic properties of real human tissue. In our laboratory we are trying to move towards the creation of
accurate replicas of real anatomy and pathology for surgical training. 3D printing plays is playing a critical role in this process.
We will also share our experience in bespoke 3D printing of patient pathology for pre-surgical planning and our perspective
on the limitations of currently available multi-material 3D printers.
