Hannover Messe 2021
In recent years, the demands placed on component-integrated electronics have risen so sharply in many industries that they can often no longer be met with conventional electronic components. As an alternative, printed electronics is on the advance.
At the Hannover Messe 2021 Digital Edition from April 12 – 16, 2021, experts from the Fraunhofer Institute for Laser Technology ILT in Aachen, Germany, will be demonstrating the role lasers play in this process. Highlights include the fully printed, smart component and the printed piezo multilayer actuators.

10:30 – 10:55 a.m. (CET) with a following Q&A session
The Fully Printed, Smart Component
Dr. Christian Vedder, Dipl.-Ing. Simon Vervoort, Fraunhofer ILT, Aachen (D)
This talk will be held in German.
In addition, the lecture will also be streamed on the
Fraunhofer All-Day-Channel on Tuesday, 13 April 2021 at 07:00 – 07:25 a.m..
In a quantum internet, several quantum computers can be connected in a completely private manner in the future and new technologies such as distributed quantum computing can be used. As part of the Fraunhofer ICON project "Low-Noise Frequency Converters for the First Quantum Internet Demonstrator - QFC-4-1QID", Fraunhofer ILT and QuTech in Delft are developing technologies that allow the wavelength or frequency of individual photons to be converted without affecting the quantum information. The aim is to subsequently transmit the photons with low loss through optical fibers and to couple qubits - i.e. the smallest computational units of a quantum computer - with each other over large distances.
At Fraunhofer ILT, the 3D printing process for producing structural components using LPBF is combined with the functional printing for the application of sensors on top and inside the components. The fully digitally produced component with component-integrated sensor technology enables permanent component monitoring and the detection of overload conditions when installed. This is combined with wireless telemetry from i4M-Technologies.
Piezoelectric layers can be deposited via a wet chemical route using PZT sol-gel materials and are selectively crystallized using laser radiation. In combination with printed electrodes in multilayer composites, multilayer actuators are fabricated that promise greater stroke and dynamics in the future. Examplary applications are printed piezo loudspeakers or microrelays
Disassembling complex components for subsequent cleaning of the individual components can be a time-consuming and costly process. Laser processes offer the possibility of cleaning complex components in their assembled state. One example is the removal of combustion residues on turbine blades of a compressor rotor.
