Source: Doris Jetter Augmented reality for mechanical and plant engineering Trends are coming about in the electronics industry with one purpose, and that is to make manufacturing faster, smarter, better, and less expensive. Dr.-Ing Philipp Klimant from the Technische Universität Chemnitz, presented on the topic of Augmented Reality and how it can help the industry continue to thrive. Virtual technologies have really made an impact in a variety of different markets, where large companies are using more and more of this for their success, including Google, Facebook, and Microsoft. Dr. Klimant emphasized that AR can be used to optimize manufacturing processes, improve error detection times, and decrease costs. This technology can be brought into any part of the manufacturing process. For instance, it can be used as a monitoring tool directly at the shop floor level, to better exchange information and knowledge. www.tu-chemnitz.de/index.html.en Methods of the characterization of aerosols from manufacturing processes with laser processing Dr.-Ing. Steffen Blei from the Institute of Air Handling and Refrigeration located in Dresden, explained the use of laser processing and its advantages. The most common uses are divided into the following categories; removing materials (cutting, drilling), welding materials, and treating surfaces (coating, engraving). Laser processing is most beneficial due to the various amount of materials it can work with. To ensure high quality as well as follow the environmental protection, the size spectrum of aerosols needs to be known to best extract and filtrate. The speaker explains the gravimetric determination method, which can be used to verify the mass of the particles. However, there are different approaches to determine the size and the particle number concentration, which all depends on the method used for laser processing. www.ilkdresden.de/en Laser Safety The risks that are involved in laser technology can be high when not handled properly. Chris Nillesen from Lapacron, a laser technology, engineering, and consulting firm, and also known as the Laser Safety Authority in the Netherlands and Belgium, discussed the biological damage that can be caused by radiation properties and partially concentrated electromagnetic power. This is why the company classifies laser products according to the IEC-EN60825. This international laser safety standard is for the protection of labor, as well as, occupational safety, which covers precautions for technical/engineering controls, administrative procedures, and personal protective equipment. The speaker explained the necessity of standardized warnings on lasers, based on their class. Especially in laser material processing, pyrolysis and evaporation can produce toxic gases, dusts, and aerosols, which must to be extracted and filtered. When ignored, the effects can be severely damaging, including irritation and burning of eyes and skin, just to name a few. www.laprocon.nl Regional development and sustainability The fundamental challenge of a growing population is keeping the balance of the ecosystem and the world as a whole. Professor Matthias Kramer highlighted controversial topics that have been around for a very long time. Although plans have been created on an international level to set boundaries, as well as, an increase in awareness of the consummation of resources, climate change, land use, and other alarming overuse of resources, the issues are still occurring. Professor Kramer discussed the past, including the triangle of sustainability that came out 300 years ago in the “Sylvicultura oeconomica” by Carl von Carlowitz, and how it correlates with the future. A particular focus of the lecture was the relationship between the regional value chains, ecosystem, companies, and how they are dependent on each other. www.tu-dresden.de/ihi-zittau Exposure to hazardous substances during powderbed based laser-additive manufacturing Complex components can be easily produced by using powderbased additive manufacturing technologies, especially when using powder bed methods. However, there is not much known yet about the effects of being exposed to contamination or by inhaling hazardous powders when using these processes.

Steffen Blei discussed how to ensure high quality and protection with laser processing. Source: Doris Jetter Chris Nillesen explained the risks that can occur when using laser technology. Source: ULT Hustedt, and Stefan Kaierle, with the help of Laser Zentrum Hannover, have done intensive research in relation to the safety and degree of contact with an opened and closed construction chamber, throughout the construction process. The team has also tested its effects with process emissions, particularly within the environment. When the chamber is closed, the exhaust and filter systems on the equipment significantly decreases any chance of exposure to hazardous substances. However, when the machine is open, during post-processing of construction for example, exposure to harmful substances can be true depending on air flow conditions and handling processes. Mr. Walter presented their findings that were focused on these specific parts of the construction process when the door is open, as well as, the time of the day, and its correlation to climate conditions, air exchange, and surface contamination. All conducted tests and investigated cases that have been done so far have not shown any excessively high amounts of hazardous particles or materials that would endanger workers or its environment. www.lzh.de additional achievements, such as bringing more control to a system or a line. For instance, the FireCS enables a smart device to control air filter systems, or the product line Dry-Tec, which controls processes based on requirements of supply air and climate. Dr. Jakschik further discussed future developments in the industry and what can be seen. This included future standards, such as OPC UA and if it will be targeted towards digital interfaces for Industry 4.0. He also discussed safety for additive manufacturing plants, disposal technology and its challenges, filter technology for the future, as well as, plant technology for low air humidity. As the future of the market will grow, the company will continue to collaborate with partners in order to follow trends and create solutions that are needed. www.ult.de Development requirements for future air handling solutions Trends and new standards have come a long way for air handling technologies, in order for processes to be safe and secure for workers and the environment. Dr. Stefan Jakschik from ULT AG discussed the accomplishments of the company, especially their recently updated platform, ULT 200, which now has higher requirements of fine dust limit values. He also went further into their Matthias Kramer highlighted the challenges of a growing population and its effects on the climate and environment.
