The 3D-printing of materials in general, and 3D-printing of metallic parts and components in particular, are in the focus of so-called additive manufacturing methods. The advantages of 3D-printing include - among others - the possibility to create objects that are not manufacturable with conventional methods, and the possibility to use less raw materials than otherwise necessary.

The applicability of 3D-printed components under fusion reactor conditions is not yet widely demonstrated due to the special requirements applicable to fusion environment. Especially stringent vacuum prescriptions and cyclic strains due to mechanical/thermal/electromagnetic loads present notable challenges.

The PhD candidate will explore, evaluate and assess the available metal 3D printing technologies accessible on the market in view of their applicability for a fusion environment. After selecting the best option, the candidate will have manufactured a special component with cooling channels, and will subject it to vacuum, thermal, mechanical and electromagnetic testing. In view of the test results, the candidate will suggest modifications to the printing procedure and formulate changes to the post-processing procedures of the components to make them more suitable for use in a fusion reactor. Manufacturing and testing activities will be carried out in collaboration with the Department of Fusion Technology of HUN-REN Centre for Energy Research.
