Finished projects

Finished projects list all projects that have been handled at the DMRC. Distinctions between internal and external projects are not made in this section but can be deduced from the “Funding”-information stated for each project under “Further project information”.

Advanced AM Material and Part Properties – Reduced Refresh Rates and Cooling Process Regarding Laser Sintering

The project deals with the recycling optimized material PA 2221, especially its ageing behavior and resulting powder and part properties. Another focus is on the cooling process of the powder cake, which is currently not known well. Therefore, a temperature measurement system is implemented within a laser sintering system. In addition, the cooling process is simulated as basis for future process optimizations.

Analysis of the FDM Part Quality manufactured with ABS with the Focus on the Toy Industry

The aim of this project is to establish a database that is necessary for the direct manufacturing of parts via the Fused Deposition Modeling in the toy industry with the material ABS. For this, not only the strength properties and the influencing parameters on the strengths have to be worked out, but a knowledge of possible surface finishing methods is also needed in order to create a component that meets the given requirements. Another very important topic is the dimensional accuracy of the parts. A very high fitting accuracy is necessary in some applications. This research project is divided into three work packages. First the mechanical strengths are analyzed, then the surface characteristics in combination with the dimensional accuracy of FDM components manufactured with the material ABS are investigated experimentally.

Development of a Strategy for the DMRC

Goal of the project is a strategy allowing the DMRC to become a leading institution in Additive Manufacturing. A strategy is a guideline for daily operations along the way towards a visionary future. It contains a mission statement, core competencies and strategic positions. Defined measures and consequences will help the DMRC to implement the strategy. In the context of this project, the fourth sequel of the study “Thinking Ahead the Future of Additive Manufacturing” is going to be released.

Direct Manufacturing Design Rules

Additive manufacturing processes create parts layer by layer without using formative tools. Hence, they have a great potential to provide new design freedoms to their users. To publish these freedoms and to support a suitable design for manufacturing, design rules for additive manufacturing are required. However, profound knowledge about such rules is not completely given at time. Thus, the Direct Manufacturing Design Rules (DMDR) project had the objective to develop design rules for additive manufacturing.
