Laser-additive manufacturing paves the way to Industry 4.0

14.11.2016

On November 09th, 2016, already for the third time, the Laser Zentrum Hannover e.V. (LZH) and NiedersachsenMetall invited small and medium-sized enterprises (SMEs) to attend the Innovation Day Laser Technology at LZH. About 100 guests informed themselves about the state-of-the-art as well as the application and market potential of the focus topic “Laser Additive Manufacturing”.

„Are we ready for implementing Industry 4.0?“, asked Dr. Volker Schmidt, CEO of NiedersachsenMetall and Chairman of the Industrial Board of the LZH, the audience at the beginning. With regard to the innovation potentials and new markets, he emphasized the high importance of digitalization. “What is the future of work in the age of digitalization?”, opened Ingelore Hering from the Lower Saxony Ministry for Economics, Labour and Transport her welcome speech with a question, too. “Only all stakeholders together can find sustainable answers to this challenge. For example here today.”


Additive manufacturing at the micro scale using Selective Laser Melting.

Laser-additive manufacturing by deposition welding can generate macro parts at high process speeds – for example for prototype construction.

Flexibly generating and repairing macro parts

Afterwards, Dr.-Ing. Jörg Hermsdorf of the LZH demonstrated how laser deposition welding can generate and repair complex structures in a short time. Dr.-Ing. Florian Wagner of the Gall & Seitz Systems GmbH impressed with mobile repair systems for parts that cannot be dismantled. With these systems for example the drive shaft of a rope drum can be repaired by mobile laser powder deposition welding. The process-technical advantages explained Mitja Schimek of the eifeler Lasertechnik GmbH: low heat input, high precision and a wide range of suitable materials.

Additive manufacturing for highest surface qualities

How Selective Laser Melting (SLM®) creates top surface qualities at the micro and macro scale presented LZH Head of Department Stefan Kaierle among other things. Bastian Lippert from the Institut für Produktentwicklung und Gerätebau (IPeG) added that weight savings of up to 40 % can be achieved with novel 3D construction models for SLM.

Market for 3D printing is still growing

“The market for industrial solutions for additive manufacturing has grown by 40 % each in the past three years”, said Frank Nachtigall of the TRUMPF Laser- und Systemtechnik GmbH & Co. KG about the market development. “And for the coming years, we expect a strong growth, too”. Professor Roland Lachmayer from the Institut für Produktentwicklung und Gerätebau (IPeG) is convinced that: „If I wonder if I could also have made the part by additive manufacturing after I finished it, I have missed 90 % of the opportunities.”

Big Data provide sales forecasts for the digital factory

How the design of a digital factory might look in the future was presented by Dr.-Ing. Malte Stonis of the Institut für Integrierte Produktion Hannover gGmbH (IPH). „A network of digital models, methods and tools forms the basis for a self-organized production that restructures itself automatically according to the order situation. The order forecast is calculated by an algorithm using search engine data.”

No innovation without skilled employees

Technical progress and market growth require sufficiently skilled employees. Worldwide almost a third of those companies who could use 3D printing are hesitating to do this, because they believe they lack the expertise. To fulfill the demand for qualified staff, recently the LZH Laser Akademie GmbH, together with the Schweißtechnische Lehr- und Versuchsanstalt (SLV) Hannover, was nationwide the first to launch the seminar “Additive Manufacturing Specialist” that has been certified by the DVS (German Welding Society).

Laser technology as a key to Industry 4.0

“Additive processes combined with laser technology are an optimum basis for merging innovative manufacturing and modern information and communication technologies”, summarizes Dr. Dietmar Kracht, Executive Director of the LZH. “Being an industry-oriented research institute, we will continue to actively further develop laser-additive processes in order to strengthen the competitiveness of the industry in Lower Saxony and beyond”.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
