4th Technology Day Hybrid Lightweighting

30. - 31. May 2017 International Congresscentrum (ICS) at Messe Stuttgart

The Technology Day Hybrid Lightweighting once again lived up to its reputation as the most popular event for hybrid lightweighting in Germany. Around 300 participants attended the event on 30-31 May 2017 in the Messe Stuttgart setting a new visitor record. The first day of conferences and the accompanying trade fair was focused on keynotes and technical sessions dealing with manufacturing technology and production. The second day of the event centered around forging successful new business relationships, particularly for SMEs. 

Leichtbau BW managing director Dr. Wolfgang Seeliger stated at the opening of the conference, "In the future, lightweighting together with digitization and additive manufacturing as well as associations of interconnected producers will become a ‘hub for megatrends’ in industrial development." Lightweighting serves to provide customers with optimal products while a digitized development chain helps make the most out of project developments. The interaction between additive manufacturing and networks of producers is able to optimize product manufacturing processes while lightweighting provides an interface to the next generation of industrial production. According to Seeliger, "all of this simultaneously offers enormous market potential and resource efficiency – which we reflect in the program of the 4th Technology Day Hybrid Lightweighting – with a view towards international markets as well". 

Session Results

Technology Day Hybrid Lightweighting | Results of Session I: Additive Manufacturing – Technological Innovations for Additive Manufacturing:


  • METAKER® Hybrid – Functionality of Composites for Functional, Design and Energy Applications | Eugen Pfeifer, AutomoTeam GmbH: Additive Manufacturing is well on the way to having the potential for serial production applications (small series), however highly complex technological approaches (development efforts) are necessary.
  • Optimal Production of Additive Manufactured Components with the Help of Industrial Computed Tomography | Steffen Hachtel, Hachtel Werkzeugbau GmbH & Co. KG: Additive manufacturing must be understood as an integral part of a process chain (CAX, CAQ, post processing, automated post processing, combination with other manufacturing technologies).

  • CARBONSPINE® - CARBON-REINFORCED EXTRUDED ALUMINUM | Lluis Raurich, engi com Engineering Community SL: The barriers of cost and service obstruct the implementation of CFP. Pultruded CFP products as support for aluminum profiles make an ideal match.
  • Thin-wall Technology in Injection Molding Using Technical Plastics for Applications in Medical, Automobile and Electronic Technology | Wolfgang Isenmann, Hans Fleig GmbH: The unique features of thin-wall injection molding technology allow detailed improvements to production processes.
  • Automatically Manufactured Lightweight Structure Components through In-Situ Polymerization | Claus Wilde, Engel Deutschland GmbH: In-situ polymerization offers an alternative to organo sheet and injection molding.

The growing significance of international markets could be felt at the Technology Day Hybrid Lightweighting as English was for the first time used as an official language of the conference in addition to German. International participants were in attendance from Europe and overseas, including from Japan and the USA. The Chinese province of Liaoning participated as a partner region to highlight its German-Chinese industrial park for machinery manufacturing in Shenyang.

Entrepreneurs and researchers used the conference and accompanying program to present numerous examples of innovation in lightweighting. Steffen Hachtel from Hachtel Werkzeugbau GmbH & Co. KG highlighted the potential for the optimal production of additive manufactured components using industrial computer cosmography. Matthias Graf from Dieffenbacher GmbH Machinen- und Anlagenbau displayed the potential and limitations of wet-processing in comparison to RTM processing. The trade fair showcased a range of developments from startups to large family owned companies such as deValu GmbH, Gaugler & Lutz oHG and Trumpf Laser- und Systemtechnik GmbH.

On the event’s second day, Leichtbau BW and its partners celebrated the successful premiere of the new business matching forum which drew more than 130 visitors. The export forum with B2B matching offered small and midsize companies the opportunity to engage in one on one discussions with potential customers, suppliers and technical developers in a "speed dating" format. Several companies including ANDREAS STIHL AG & Co. KG and Prea Ltd. took part. This portion of the event was organized in collaboration with partners from enterprise Europe network and Handwerk International Baden-Württemberg.

Innovative and technology oriented companies in their start-up and growth phases also had the opportunity to convince potential investors of their ideas in 15 minute pitch blocks during the innovation and investment forum. Pitches were presented by CIKONI composites innovation TTI GmbH, pohltec metalfoam GmbH, Smart Composites, TruPhysics GmbH and Renumics GmbH. In addition, the event offered first-hand information on setting up new companies and securing financing for new developments and growth. This part of the Technology Day Hybrid Lightweighting was also featured as part of the CyberOne Roadshow.

The 4th Technology Day Hybrid Lightweighting took place in the ICS International Congress Center Stuttgart and was presented by the Developement Agency for Lightweighting BadenWuerttemberg and its partners. The next Technology Day Hybrid Lightweighting will take place on 25-26 June 2018 in Stuttgart.
