Laser- Induced Direct Metallization of Additively Manufactured Alumina Substrates for Ceramic 3D Mechatronic Integrated Devices

Laser-induced Direct Metallization (LDM), is a 3D capable selective metal plating process. Recent research
on LDM of oxide ceramics now enables plating of fine metallic structures such as conducting paths or
antennas directly on 3D surfaces of alumina components. This allows for the manufacturing of ceramicbased
so-called 3D-MID (Three Dimensional Mechatronic Integrated Devices) integrating electronic and
structural functionalities that can withstand extreme thermal, chemical and tribological conditions opening
up new fields of applications. Additive Manufacturing (AM) of alumina substrates for 3D-MID could
further increase their application range due to its flexibility in component design and profitability for small
lot sizes or prototypes. Transferring existing results on injection moulded alumina substrates to AM technologies,
however, poses some technical challenges. This article presents LDM of alumina ceramics and
different pathways towards substrates for a new generation of ceramic 3D-MID at a glance.
