Production of Topology-Optimized Structural Nodes

A method involving arc-based, additive manufacturing with MSG welding process
Jan Reimann, Stefan Hammer, Philipp Henckell, Yarop Ali, Jörg Hildebran, Jean Pierre Bergmann
In this paper, the creation of strength and stiffness-adapted structural nodes using the numerical simulation method of topology optimization is presented. The resulting node is transferred into a robot path planning by means of CAD/CAM software and manufactured with wire arc additive manufacturing (WAAM) with the GMAW process using the welding filler material G4Si1.

Additive Manufacturing for Industrial Applications

Additive Manufacturing for Industrial Applications

Development of a Methodology for Integrating Added Value into Products by Additive Manufacturing
Thomas Papke, Dominic Bartels, Michael Schmidt, Marion Merklein, Daniel Gerhard, Jonas Baumann, Indra Pitz
Additive Manufacturing has become more important for industrial applications. The technology offers the opportunity of high geometric flexibility and no need of product specific tools including short time to market. The aim is to integrate added value into products by exploiting these possibilities. Therefore, in this work a methodology focusing on these aspects is developed and applied to a structural component.

Additive Manufacturing of Metallic and Ceramic Components

Additive Manufacturing of Metallic and Ceramic Components

Use of Material Extrusion, Especially the Use of Filaments for Sintering Processes
Christian Kukla, Stephan Schuschnigg, Clemens Holzer
The filament printing presented here can be used to produce metallic and ceramic components with complex shapes. Filaments in various highly filled polymers are available for the process. By means of the Shaping-Debinding-Sintering process the green bodies are converted into metallic/ceramic components. As with the PIM process, the filament printing can be used to produce near-net-shape parts, whereby the sintered bodies have a linear shrinkage of 15-20 % compared to the green bodies. In order to produce parts of very high quality, the printing process must be controlled accordingly.

Holistic Clamping and Referencing

Holistic Clamping and Referencing

Improving 3D printing and further processing of metal parts
Moritz Wollbrink, Semir Maslo, Kristian Arntz, Thomas Bergs
The manufacturing share of laser powder bed fusion (L-PBF) increases in industrial application, but still many process steps are manually operated. Additionally, it is not possible to achieve tight dimensional tolerances or low surface roughness. Hence, a process chain has to be set up to combine additive manufacturing (AM) with further machining technologies. To achieve a continuous workpiece flow as basis for further industrialization of L-PBF, the article presents a novel substrate system and its application on L-PBF machines and post-processing. The substrate system consists of a zero-point clamping system and a matrix-like interface of contact pins to be substantially connected to the workpiece within the L-PBF process.

Implementation of Additive Manufacturing

Implementation of Additive Manufacturing

An Analysis of Supply Chain Related Decision Factors of the Implementation Decision
Ralf Elbert, Anne Friedrich, Elisa Schuhmann
Additive manufacturing technologies, such as 3D printing, have reached a stage of performance for industrial application such as small series and spare parts. The adoption of additive manufacturing has so far mostly been investigated from the perspective of individual manufacturing firms. This paper focuses on the identification of overarching influence factors. In a category system, influence factors are analyzed from the perspectives of the supply and demand side, the supply chain actors and flows as well as sustainability, thus contributing to the adoption from a supply chain perspective.

Heterogeneous Fields of Application in Additive Manufacturing

Heterogeneous Fields of Application in Additive Manufacturing

Henrik te Heesen, Michael Wahl, Mats Bremer, Adrian Huwer ORCID Icon, Joachim Messemer
Additive manufacturing is a central component of the fourth industrial revolution, which was initiated a few years ago. The growing interconnection of machines and processes and the ever-increasing individualization of customer needs mean that manufacturers have to adapt to changing markets in a continual process due to global competition. The production of prototypes or individual series using machines that produce complex three-dimensional workpieces is becoming increasingly important for manufacturing companies and, thus, for research institutions in the training of qualified specialists.

Industrial Application of 3D-Printing Systems

Industrial Application of 3D-Printing Systems

General Guidance
Martin Bednarz
Additive Manufacturing (AM), also commonly called 3D-Printing, is very recent technology. Numerous innovations have improved their capabilities in the last few years. These improvements combined with ambitious promises made by 3D-Printing companies have led to some disregard of the physical and economical limitations of these technologies. As impressive as the opportunities especially in light weight construction may be, the technical, physical and economical restrictions have to be considered. This article focuses on the premises and restraints as well as the opportunities of AM-technology.

Lithography-based Metal Manufacturing

Lithography-based Metal Manufacturing

New Additive Manufacturing Technology to Produce Small High-precision Metal Components
Andreas Baum, Chiara Armbruster, Carlo Burkhardt
Additive manufacturing (AM) has become one of the biggest trends in modern, industrial ma-nufacturing. The diverse requirements of various industries have led to many different AM processes and process variants. By using AM, advantages such as function integration, lightweight construction or increased efficiency can be enabled. But most of the known AM processes are still facing technological and economic challenges. Especially in applications requiring high accuracy for small parts, production has often been uneconomic until now. Here, the new Lithography-based Metal Manufacturing technology offers new possibilities and opportunities.

Blockchain as Enabler of a Decentralized Additive Manufacturing Production Network

Blockchain as Enabler of a Decentralized Additive Manufacturing Production Network

Wjatscheslav Baumung, Herbert Glöckle, Vladislav Fomin
The toolfree production of parts using 3D printing technology enables dynamic use of the production area. On the one hand, this makes it possible to react flexibly to changes and, on the other hand, to achieve a high level of efficiency in the production units. The blockchain technology enables a common database between the participants. This leads to a verifiable collaboration in the case of the relationship between customer and manufacturer. This paper describes how available additive manufacturing resources can be identified and offered in a decentralized production network.

Current advances result in increasingly complex production programs. Through combination of additive manufacturing and Industry 4.0, new elements can be formed and - as a whole - enable to economically manufacture the above mentioned programs. The Bionic Smart Factory 4.0 provides a framework, structuring them in terms of relation and interaction. Their development and implementation is being promoted through their evaluation against the determinants of complex production programs.
