dunkyboy Posted September 13, 2016 Share Posted September 13, 2016 Our hospital is treating a 17 y.o. patient who requires a large prosthetic/implant which will sit below the sternum to the base of the rib cage. Approx 300mm x 200mm x 100mm. We are attempting to identify solutions for the materials that could be used for such a device. Currently, the main implantable material we have identified is silicone, with a fairly high hardness. The concerns we have is that this prosthetic would be very heavy for such a large object if printed in silicone. The properties we are looking for are: 1. Hardness that aids in the structure of the patient's chest 2. Soft extremeties - for comfort and aesthetic 3. Reasonable weight My thoughts are for a plastic (maybe PLA) scaffold bound by silicone. I'm looking for any suggestions as to possible hybrid/multi material solutions that are medical grade and permanent. Link to comment Share on other sites More sharing options...
Dr. Mike Posted September 26, 2016 Share Posted September 26, 2016 Most of the custom designed bone replacement 3D printed implants I have seen are titanium or steel, which can be sterilized. What is the purpose of the implant? Is this a replacement for a resected rib cage? Link to comment Share on other sites More sharing options...
