The Fraunhofer Institute for Laser Technology ILT established and hosted the first international conference on laser polishing. From May 6-7, 2014, over 70 local and international scientists and laser technology users from various sectors of the industry met in Aachen, Germany. During five different sessions, 14 speakers from six countries expounded topics related to the laser polishing of glass and metals.
Despite a steady increase in recent years in the number of working groups, publications and projects on the subject, laser polishing is still considered a niche technology.

This prompted Fraunhofer ILT to organize the 1st Conference on Laser Polishing LaP 2014 in Aachen, Germany. Headed by Dr. Edgar Willenborg, their event created an international platform for exchanging scientific findings in the laser polishing field. A total of 14 lectures were held in English, providing over 70 participants from 10 countries with the opportunity to gain a comprehensive picture of latest scientific developments and first industrial applications of laser polishing.
Industrial laser polishing
Dr. Thomas Kiedrowski (Robert Bosch GmbH) introduced a metal polishing application that is already in use today and with which millions of components are laser-polished annually. His presentation centered on an example taken from CVT production.
Two lectures given by Dr. Manyalibo Matthews (Lawrence Livermore National Laboratory) and Dr. Philippe Cormont (CEA CESTA) explained another way in which these new methods are being employed successfully, this being to repair optics for high-power laser systems by means of CO2 laser radiation.

In addition to the lectures, a further highlight for conference participants was a tour of the laboratories at Fraunhofer ILT that let them see the latest laser polishing machines and test set-ups. Among other things, visitors were shown a live demonstration of the adaptive laser polishing machine for the polishing of metal work pieces that was developed as part of the BMBF-funded ALPINE project.
The success of the 1st Conference on Laser Polishing – LaP 2014 reflects the great interest the scientific and industrial communities have in this new manufacturing process. There is clearly a significant demand for a cost-effective, automated finishing process that offers an alternative to conventional abrasive methods. This demand will continue to drive research in this area in the future, so we can expect more exciting developments in the field of laser polishing to be unveiled at the 2nd Conference on Laser Polishing – LaP 2016 from April 26-27, 2016 in Aachen.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
