Biocompatible, 3D-Printed Housing Created for Microdevices to Be Implanted in Brain

(3D Printing Industry) — Deakin University’s School of Engineering students have released a report detailing experimentation with 3D-printed, biocompatible enclosures for microdevices. The project is aimed at creating 3D-printed housing for electronic, medical microdevices made to be implanted for deep brain stimulation. What makes the 3D-printed enclosures so important to these devices is the biocompatible nature of printable materials, which, in this project, includes medical-grade silicone and other viscous liquids and pastes. In its report, biocompatibility is defined as “compatibility with living tissue or a living system by not being toxic, injurious, or physiologically reactive and not causing immunological rejection.”

The team designed these physical casings through CAD program SolidWorks, creating three prototypes thus far. Using the EnvisionTEC Bioplotter 3D printer, which prints at a rapid pace and in multiple types of material, the enclosures were built with a defined form and an open inner structure. The team chose to utilize the Bioplotter over more traditional 3D printers due to its ability to accurately print with biocompatible silicone material.
