Researchers at Fraunhofer IKTS developed a robust solution for the individual labeling of components and products. It withstands extreme environmental influences, can be applied within seconds and read-out reliably. Therefore, the new development is suitable for the integration into industrial plants.
Many raw materials and semi-finished products are exposed to extreme conditions in manufacturing processes or in application, for example high temperatures in metal processing or the glass and ceramics production.
In other areas, such as the leather industry or cleaning processes in the food and pharmaceutical branch, aggressive chemicals are used. Even climate and environmental influences place special demands on the surface of workpieces.
Such extreme conditions can hinder or even render the use of an individual component labeling based on barcodes or matrix codes over the entire process chain impossible. The reasons for this are varied, for example an insufficient thermal and chemical resistance of the codes, a lack of contrast and readability or corrosion during the application of the labeling.
To meet these challenges, researchers at Fraunhofer IKTS developed the CeraCode® technology. It is based on ceramic luminescent materials for inkjet printing. These materials display a pronounced luminescence in response to optical excitation, for example by UV radiation.
For an individual labeling, a special ink with luminescent materials is being printed onto the component. Implemented as barcode or data matrix code, the labeling provides a high contrast to the subsurface, regardless of ambient conditions. The ink shows excellent adhesion to various materials and is highly resilient both thermally and chemically.
“The applicability and robustness of CeraCode® has already been successfully demonstrated in the laboratory and at first pilot customer facilities. The focus of current IKTS research is on the integration of the labeling solution into existing processes. We succeeded in printing series components in the shortest possible time of less than 100 ms“, explains Dr. Thomas Härtling, scientist at Fraunhofer IKTS.
Today, the institute is able to offer a complete solution, ranging from the development of process-suitable ceramic inkjet inks to the generation and printing of the necessary codes and the adjustment of appropriate readers.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
