Selective laser sintering of metal and ceramic compound structures
In different application scenarios, compound structures of different material like metal and ceramic are needed to increase durability and reliability of industrial goods with reference to surface hardness, wear and temperature stability. Therefore, selective laser sintering has been tested in experimental series, how such structures could be generated. This article describes achieved results of the basic targets (connection mechanism, creation of interfaces, bonding forces, homogeneity and porosity) and concludes with technical application.

Hi. I noted your video presentation is without audio commentary. If you are using the method proposed by the
iproms website (http://conference.iproms.org/how_to_create_a_video_presentation ), please ensure that the checkbox for "Capture audio from default audio device" is ticked or checked (if you refer to the second snapshot of the website, you will see
the snapshot is shown without the tick on the checkbox,
please tick it) when you record your video presentation.
Thank you.
Many thanks for your interest in this work. There has not been an investigation of fusing other materials than ceramics, because IMW just uses DMLS. Due to that, there are some restrictions based on Laser etc.
You are right, that similarities exist in comparison with Functionally Graded Materials. Applications for these materials might be mouldings for plastic and metal, tools for sheet forming and moulding ties, coverings for combustion chambers or cylinder heads and valves in engines (s. presentation). The surface finish has to be researched further because surface quality is not sufficient right now.

Have you investigated fusing metal with other materials (not just ceramics)? This work seems to be similar (if not the same) as Functionally Graded Materials - where different materials are combined to achieve desired functionality. What applications have you considered for these materials? What quality of surface finish are you able to obtain?
