Ripley leads the VHA’s 3D Printing Network and chairs the VHA 3D Printing Advisory Committee. When clinicians are preparing for a reconstructive surgery, both the patient and the surgeon can visualize a procedure by working with a customized 3D model. VHA dentists can use 3D printed models to plan dental implants. Occupational therapists use 3D scans and printers to manufacture custom orthotics with same-day fitting and delivery. During the COVID-19 pandemic, Ripley led a team of engineers, researchers, clinicians and regulatory specialists to design and test 3D printed personal protective equipment, nasal swabs, pipette tips and other needed medical devices to support front-line staff.
