| Description | We have shown the feasibility of 3D printing customised stents that achieve the required performance for nitinol through the optimisation of 3D printing parameters, alloy chemistry, and post-processing. The results could also be utilised to create preforms for stents that can then finished to reduce the processing time required to manufacture the stents. In theory, over 100 stents can be 3D printed in 1 hour. Laser micromachining, the current fabrication method for stents, produces significant waste, and is an energy intensive process. |
| Exploitation Route | Johnson Matthey, one of the partners in this programme, have connected us to various material suppliers in their organisation (Johnson Matthey medical) to assess the potential for commercialisation. A patent application is currently being drafted. |

| Sector | Academic/University |
| PI Contribution | Due to our current involvement in the EPSRC funded programme on 3D printing of smart stents for lower extremity (total value £1M), we support the project by Prof. Triona Lally using our expertise on stents 3D printing due to the significant overlap with your proposed investigation. We supply the following in-kind support to this project: • Use of SLM equipment (approximate costs based on commercial rates): £10,000 • Powder: £2,000 • Attendance of 1 review meeting in Dublin: £250 • Powder characterisation (based on commercial rates): £500 |
| Collaborator Contribution | Prof. Lally's team provide us with new applications for 3D printing of commercial stents. |
