DISSERTATION ADDITIVE FERTIGUNG

A multi-component evaporation model for beam melting processes In: In the further course the additive manufacturing value chain, its development, and involved stakeholders are outlined. The powder bed based selective electron beam melting process allows to produce complex components from high performance alloys. Ein weiterer wichtiger Aspekt sind die zu erwartenden wirtschaftlichen Potentiale, die sich aus einer Reihe technischer Charakteristika ableiten lassen. Activity Development of process strategies The electron beam offers the potential for innovative selective beam melting process strategies due its inertia-free deflection at extremely high speed. Process influences, such as temperature distribution, scanning strategies, and electron beam properties are investigated using both a thermal and a high-speed camera.

Today, for the first time, the increasing number of 3D printing service providers and the constantly growing range of affordable printers for home use, make this technology available to consumers, whereas the high costs limited the use to large enterprises in the past. Insbesondere Fragestellungen zu wirtschaftlichen und gesellschaftlichen Auswirkungen haben hingegen kaum Beachtung gefunden. 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. Jedoch haben sich Wissenschaft und Forschung bisher vor allem mit Verfahrens- und Materialfragen befasst. 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. Activity Structural reactors of catalytically active materials We investigate new alloys for structural catalysts that serve as carrier material and simultaneously as catalytically active material in structured reactors.

Today, for the first time, the increasing number of 3D printing service providers and the constantly growing range of affordable printers for home use, make this technology available to consumers, whereas the high costs limited the use to large enterprises in the past. Additivee of the project is to understand dissertqtion basic mechanisms during selective electron beam melting and to use this knowledge to predict and to influence the resulting materials quality. Richtet man den Fokus jedoch nicht auf die Technik, sondern die Hobbyisten selbst, lassen sich neue Einblicke in die zugrunde liegenden Innovationsprozesse gewinnen.

For that reason, an explorative study of remixing activities on the platform was conducted and is presented.

Immediate development of processing windows for selective electron beam melting using layerwise monitoring via backscattered electron detection In: Jedoch haben sich Wissenschaft und Forschung bisher vor allem mit Verfahrens- und Materialfragen befasst.

Macroscopic simulation and experimental measurement of melt pool characteristics in selective electron beam melting of Ti-6Al-4V In: Numerical simulation of multi-component evaporation during selective electron beam melting of TiAl In: Structure design rests upon basic knowledge about mechanisms generated by numerical simulation.
