Multi-material additive manufacturing in architecture and construction: A review

Abstract: Multi-Material Additive Manufacturing (MMAM) is an emerging manufacturing approach that is gaining interest in architecture and construction as an expansion of Additive Manufacturing. Hereby, different materials or material properties are combined in a single additive process in order to create objects that are composed of multiple materials. Ultimately, this approach introduces a new way of manufacturing and building, where assembly is no longer a necessity in order to combine multiple materials. Moreover, different potentials can be derived from the use of MMAM. Leading towards components with heterogeneous material composition and a high degree of adaption towards structural, environmental, and design criteria. This work provides an overview of the current state of MMAM in architecture and construction. Different processes and materials which have been reported are discussed and potentials, which emerge through the use of MMAM are described using specific use-cases.

Interface connecting the INET simulation framework with the real world

Abstract: The INET framework for the widely used OMNeT++ simulation environment supports discrete event simulation for IP-based networks. During the development of a simulation model for the new IETF transport protocol SCTP (Stream Control Transmission Protocol), INET was extended to also support external interfaces. These interfaces allow to set up hybrid scenarios where simulated nodes communicate with real external IP-based nodes. This paper will first give a short introduction to the OM-NeT++ simulation environment and the INET framework. Then the requirements for the external interfaces will be discussed and some implementation aspects will be described. Hybrid scenarios offer a whole range of potential applications which will also be presented briefly. The performance of this technique is crucial for its applicability. Therefore, several test setups are evaluated to verify the feasibility of this approach.

Thick films of ceramic, superconducting, and electro-ceramic materials

Abstract: The use of thick films becomes more and more important in particular for elec- tronic and microelectronic applications. The term "thick film" does not relate so much to the thickness of the film but more to the kind of deposition. Thick films are made by low-priced processes such as doctor (dr) blading, screen-printing, or spraying methods, etc. The prepa- ration of thick films of ceramic material by these methods generally implies a processing sequence of the following steps: preparation of the oxide powders; preparation of pastes and slurries; painting/printing, etc. of the pastes onto a suitable substrate; drying at low tempera- ture; and sintering at high temperature to get a consolidated layer. These technologies and the fabricated thick films of thermoresistive and superconducting materials will be discussed.
