Direct Laser Fabrication (DLF)

The work on Direct Laser Fabrication can be divided into four themes:
  1. Fabrication of large near net-shape structures
  2. Cladding / Repair / Hybrid manufacturing
  3. Microstructure optimization using various laser operating modes
  4. Structural integrity study and microstructure characterisation

In this project, structures above one meter in length will be fabricated using Ti-6Al-4V. Such structures are currently considered as a challenge within the aerospace industry and therefore SAMULET 4 was considered a technologically unique activity.

 Description The focus of this project are smart stents used for treatment of peripheral arterial disease. A stent is a wire mesh tube which is implanted into an artery, where it acts as a scaffold and keeps the artery open. The goal is to manufacture stents from the shape-memory alloy Nitinol. This has the potential to make insertion into the artery easier and safer. Using additive manufacturing, specifically selective laser melting (SLM), offers further advantages in terms of design flexibility, as well as a cheaper and less wasteful manufacturing process.
