Mr Anders Hjermitslev (Danish Technological Institute)


The Danish industry has been reluctant to adopt Metal AM, despite the enormous potential for tailored and flexible manufacturing. A national granted project called: “AM-LINE 4.0” (2018 – 2021) has paved the way for the Danish manufacturing industry by removing barriers preventing implementation. The project has a total budget of 12M EUR and is a partnership with the leading industrial partners: Grundfos, Danfoss, SLM Solution, and TWI; together with The Danish Technical University.

The Danish Technological Institute is project manager, and this oral presentation will summarize the main results of the project from a combined industrial and academic point of view. The following topics will be discussed during the presentation:

• Identification of business cases in large organizations and redesign for Metal AM. Examples for Grundfos and Danfoss will be shown together with State-of-the-Art optimization methods as: Distortion compensation with thermomechanical simulations, lattice structures, and thermal topology optimization.

• Quality Assurance procedures for Metal AM by utilizing IoT. An effective cloud-based storing of all production data, that can be used to make cost-effective Quality Control - combined with the main results from the article: “Towards a digital twin of laser powder bed fusion with focus on gas flow variables” [Klingaa, et al] will be submitted later in February 2021 to Elsevier Journal of Manufacturing Process.

• Various micro- and macro-based modelling approaches on laser powder bed will be discussed. These models cover different topics as for instance: Micromechanics and fatigue life estimation, tailored heat treatments of additively manufactured materials, porosity estimation, and geometrical distortion. Several publications have been made by the Danish Technical University and this presentation will cover an overview of the main results.
