Title
3D printing of diamond for biomedical and biomaterial applications
Abstract
Diamond is an interesting biomaterial with history as a coating material for orthopaedic interfaces and heart valves as well as the electrode system for high-profile projects such as the Australian Bionic Eye project. As is well established, 3D printing is changing the way that we as biomedical researchers approach patient-specific solutions. The challenge however for a material like diamond is the upscale to complex shapes and parts. By combining 3D printing we can achieve this. I have previously shown that we can use SLM titanium as a substrate for the coating of diamond onto complex parts. Here I will discuss the methods we have developed to combine 3D printing and diamond, discussing the new material and reporting on the superior cell/antibacterial interface (compared to titanium alone). In particular, I will report on:
1. The use of diamond as an electrode material for bionic implants
2. The use of nanodiamond-polymer composites for in vivo imaging
3. The results of our new method of using laser metal deposition (LMD) to print free-standing diamond-titanium materials for implant engineering show the results of our first animal trial that reveals that diamond provides a superior implant material to SLM titanium.
