DISSERTATION ADDITIVE FERTIGUNG

Numerical microstructure prediction by a coupled finite element cellular automaton model for selective electron beam melting In: Subsequent diverse business models out of the additive manufacturing context are systematically visualized and elucidated. An additional contribution that extends previous research on innovation processes is the identification and description of six different remix processes that can be differentiated by means of the features skill level, trigger and motivation. Insbesondere Fragestellungen zu wirtschaftlichen und gesellschaftlichen Auswirkungen haben hingegen kaum Beachtung gefunden. In the further course the additive manufacturing value chain, its development, and involved stakeholders are outlined. The findings of a qualitative study with more than 75 designers show amongst other findings, that designers have already internalized the concept of remixing and apply it in various contexts, even beyond the platform.

This knowledge will be used to validate multi-level process models that can predict AM processes, part quality and performance. August – 3. For that reason, an explorative study of remixing activities on the platform was conducted and is presented. However, not focusing on the technology itself but on the hobbyist users reveals new insights on underlying innovation processes. Besides materials libraries we are also able to realize multi-material and graded components. Additive manufacturing of nickel-based superalloy Inconel by selective electron beam melting: Additive manufacturing of single crystalline superalloys Project B2 explores selective electron beam melting, which belongs to the additive manufacturing technologies, for the processing of single-crystalline superalloys.

Advanced Engineering Materials 10p. This machine is equipped with four powder hoppers in a glove box with inert gas atmosphere.

In order to reach this aim, the selevtive electron beam melting process takting selective vaporation phenomena into account is simulated based on a Lattice Boltzmann Model. Fabrication and characterisation of a fully auxetic 3D lattice structure via selective electron beam melting In: One key output of the project will be the knowledge surrounding the use of the high powder electron beam gun, including the process control, and modeled and validated understanding of beam-powder bed interaction.

The conclusion of the findings show, that there is room for growth with regard to complexity, enhancement of efficiency, and variety of versions. Presently science and research focuses primarily on questions regarding materials and processes, while ignoring avditive missing out the discussion about economic and social impact.

In the second phase, the previous model is transferred to polymers. Another important aspect are expectable economic potentials that can be deduced by a number of technical characteristics.
