DISSERTATION ADDITIVE FERTIGUNG

For that reason, an explorative study of remixing activities on the platform was conducted and is presented. Single phase 3D phononic band gap material In: In the first phase, a tool for the 2D simulation of selective electron beam melting was developed and validated with experimental results. Evaporation model for beam based additive manufacturing using free surface lattice Boltzmann methods In: Scripta Materialia , p. One of the cases deals with the popular online platform and community Thingiverse that offers a platform for publishing, sharing, access, and remixing a broad range of printable digital models.

Journal of Physics D: However, despite its obvious relevance for the number and quality of innovations on such platforms, little is known about the process of remixing and its contextual factors. Microstructure and mechanical properties In: Simulation of grain structure evolution during powder bed based additive manufacturing In: We are designing building strategies to avoid cold and hot crack formation. Concerning pure Copper and Copper alloys our focus is on the influence of minor elements or contaminations such as Oxygen or Phosphorus on the resulting properties, in particular the achievable heat conductivity.

Modelling of electron beam absorption in complex geometries In: We investigate new alloys for structural catalysts that serve as carrier material and simultaneously as catalytically active material in structured reactors. In particular, the potential to tailor the microstructure, grain structure and texture of the material with the help of the extremely high beam velocity is explored. The powder bed based selective electron beam melting process allows to produce complex components from high performance alloys.

Another important aspect are expectable economic potentials that can be deduced by a number of technical characteristics. Evaporation leads to material loss, has influence on addittive melt pool dynamics and changes the alloy composition.
