MIRS 3D Printing Lab

The MIRS 3D Printing Lab is available to help build 3D-printed anatomic models, patient-specific surgical aids, and prototypes for research or feasibility analysis. Our current 3D printer, a Formlabs Form 2, uses several types of light-sensitive resins (SLA functionality). Each resin has unique physical properties and may be opaque or translucent, depending on the needs of the finished print. Most prints are from of the following categories:

•    Anatomic instructional models (general, not patient specific)
•    Patient specific pre-surgical planning models (usually anatomic models)
•    Patient specific surgical tools (cutting and drilling guides)
•    Research and development prototypes

The MIRS 3D Printing Lab welcomes inquiries to schedule consultations. Projects are accepted on a case-by-case basis.

Featured 3D Project

Vestibular Ring Model featuring Semi-Circular Canals & Cochlea

This 3D printed model of the inner ear (Vestibular Ring Model) is designed for educating patients and students about how repositioning the head can move otoconia or canaliths which have entered one or more semi-circular canals. Moving these little "stones" in a desired direction is a part of the treatment for Benign Paroxysmal Positional Vertigo (BPPV).

This version features a translucent resin model of the three semicircular canals and cochlea. Three different color metal rings were attached to identify the superior/anterior canal (silver ring), horizontal/lateral canal (copper ring) and posterior canal (gold ring). The rings are able to slide along each canal, much in the same way an internal otoconia or canalith would move within a fluid-filled semicircular canal. 

Bilateral model pairs were printed in two sizes to provide large teaching model kit and a smaller traveling/personal model kit. On the smaller models, the metal rings are graduated in size with the smallest diameter being the silver ring and the largest diameter for the gold ring.  This feature could assist visually impair patients in benefitting from instruction using the Vestibular Ring Model. 

These 3D models were printed at the MIRS 3D Printing Lab (January 2018) at the request of Elizabeth Hile, PhD, PT, the Director of Cancer Rehabilitation Science Program for the Stephenson Cancer Center at OUHSC. Dr. Hile is a Board Certified Specialist in Neurologic PT and is a Norton & APTA-Certified Edema Specialist (CLT/CES). She serves as an Executive Board Member, Oklahoma Center for Neuroscience (OCNS). Dr. Hile is an Assistant Professor of Rehabilitation Science in the College of Allied Health at OUHSC. Her email address is Elizabeth-Hile@ouhsc.edu.

3D Printing Special Interest Group (3D Pr SIG)

MIRS Faculty also coordinate the 3D Printing Special Interest Group (3D Pr SIG), which serves as an avenue to explore collaborative opportunities for 3D printing in education, research, scholarship, and patient care. The 3D Pr SIG encourages collaboration with faculty, staff and students, including OU Norman School of Biomedical Engineering and Colleges on the OUHSC and OU campuses.

The initial goals of the 3D Pr SIG are to provide education to broaden the knowledge and application of 3D printing in medical imaging, patient care, and improve patient outcomes through various interdisciplinary discussions and skills-building sessions. This includes exploring design creation, software implementation, advanced modality image manipulation, and various additive manufacturing printing processes to bring designs and image data sets from concept to functional models.
