One of the largest challenges in simulation for Additive Manufacturing is
the wide range of process and product specific relevant scales. This is not
only true for the spatial scale, but in many cases even more for the
temporal scales. Considering as an example Selective Laser Melting, and
only focussing on a ‘macroscopic’ process simulation, the geometric scale
of the laser spot and that of the typical length of a printing path differ
by five to six orders of magnitude. The same scale range is relevant in
time, when the local heating time and that of the full printing process of
a part are considered. Even if only small, representative parts of
SLM-processes are to be simulated, adaptive methods are mandatory.
While significant research has been conducted over the last few years on
spatially adaptive AM simulation, only few results are available on the
specific challenges of simultaneous spatial and temporal adaptation. In
this talk, we will address a new approach applying space-time finite
elements, with a fully 4-dimensional adaptation with respect to mesh and
polynomial order of the shape functions. A data structure allowing the
hp-adaptive n-dimensional simulation will be discussed.
In the second part of the talk, we will address questions w.r.t. the large
range of relevant scales for AM products. Geometric shapes and scales play
an important role to control mechanical properties of built parts e.g. in
case of lattice structures or for composite materials being designed to
meet specific viscoelastic damping requirements. We apply a combination of
the Finite Cell Method with an extension of the Mortar Method to develop a
simulation system for optimizing viscoelastic properties of printed parts.

*Ernst Rank* is Professor emeritus from the Technical University of Munich.
He studied Mathematics and Physics at the Ludwig-Maximilians-Universität of
Munich and was awarded a doctorate from the School of Civil Engineering at
the Technical University of Munich in 1985. Following a research year in
the US and employment in an industrial environment at Siemens, he assumed
in 1990 a professorship for Numerical Methods and Computational Sciences at
the University of Dortmund, after which he was appointed to TUM in 1997.
Until 2019, he held the Chair for Computation in Engineering. Professor
Rank was the Vice President for Research of TUM from 2002 to 2008. From
2006 to 2016, he was the Founding Director of the International Graduate
School of Science and Engineering (IGSSE), and from 2015 to 2019, he held
the position of Director of the TUM Institute for Advanced Study.

Professor Rank conducts research on numerical mechanics and engineering
informatics. His work focuses on high-order finite elements, immersed
boundary methods, the integration of numerical simulation with geometric
modelling and on efficient simulation with applications e.g. in biomedical
engineering or in additive manufacturing. A central objective is to develop
effective and intuitively usable simulation methods for the optimisation of
industrial products and processes.

*Professor Rank is author or co-author of more than 400 papers in
international journals, book chapters and peer reviewed conference
proceedings.  Among other awards he obtained the Konrad-Zuse Medaille
(2009), the Federal Cross of Merit (2009), is Corresponding Member of the
Nordrhein Westfälische Akademie der Wissenschaften und Künste (2014) and
Member of the Bavarian Academy of Science (2017). Since 2018 he is Fellow
of the International Association for Computational Mechanics (IACM).*
