Mathematics for electron beam melting – 3D printing in metal

Industry PhD position at Arcam AB and Chalmers University of Technology

3D printing, or additive manufacturing (AM), is an emerging technology that has gained a lot of attention recently. In the area of AM, electron beam melting (EBM), developed by the Swedish company Arcam AB in Mölndal, has taken a unique position by offering metallic parts of high quality materials for serial production of medical implants and aerospace parts.  In the EBM process metallic powder is melted layer by layer by a high energy, focused electron beam. The layers are melted onto each other and form a 3D part directly from CAD data.  The electron beam melts the powder by scanning over the layer at a high a speed.

In order to improve the melting process, and at the same time make 3D printing by EBM more transparent for validation, new mathematical models and simulation algorithms for the EBM process will be developed in this project.  This will make it possible to control and validate the EBM process from computed temperature distributions.  The developed computational methodology, based on finite elements and model order reduction, will be of scientific interest in computational mathematics.

The project is a collaboration between Arcam AB and the department of Mathematical Sciences at Chalmers with financial support from the Swedish Foundation for Strategic Research (SSF).  We now seek a PhD student.
The PhD student to be recruited should have a Master degree (or equivalent) in mathematics/applied mathematics or engineering with a strong focus on scientific computing.  Experience with modern programming languages is essential.
The student will have a full-time employment at Arcam AB combined with enrollment as a PhD student in the department of Mathematical Sciences at Chalmers.   Four years of full-time research and study is expected to lead to a PhD degree in Applied Mathematics at Chalmers.
