Experts from research and industry will give novel insights into the latest developments around chocolate. We are glad to present you a divers and informative program with topics ranging from technology to markets, analytics to sustainability, processing to health aspects etc. These three days will be fully dedicated to the world of chocolate and we are now pleased to present you here the speakers that will forward their knowledge and experience to the audience: __________________________________________________________________________________________________________________________________________________

Dr. Kjeld van Bommel, Senior consultant 3D Lebensmitteldruck, TNO Eindhoven - 3D food printing: shapes, recipes, and textures

Kjeld van Bommel studied Chemical Technology and subsequently obtained his PhD in Supramolecular Chemistry at the University of Twente (the Netherlands) in 2000. After having worked on organogel chemistry for many years he moved to TNO in 2006 where he worked as a research scientist on various material related topics such as encapsulation and controlled release, as well as surface modification chemistry. in 2010 he moved to the Equipment for Additive Manufacturing department in which he currently works as a senior consultant with a focus on the field of 3D Food Printing. 

His presenation:

TNO has been operating at the forefront of 3D food printing for many years.
The unique combination of 3D printing and food knowledge, as well as facilities allows TNO to work on a wide range of 3D printing technologies, food materials, and applications.
This presentation will give an impression of the possibilities the various 3D printing technologies offer with respect to shapes, recipes, and textures.



Gunther Bigl, Geschäftsführer Formicum 3D-Service GmbH

Application possibilities of 30 paper printing: Prototype production and individualization of the product and packaging

During this presentation the author will discuss the strengths and weaknesses of 3D-Paperprinting and show possible use-cases for that printing technology.

He will show the general workflow and present some interesting recent developments of this technology. Last but not least some examples of recent projects are shown and discussed.


Production of individual chocolate molds for one-time production and small batches by additive production

This presentation will show the possibilities to make real products for the chocolate production. With the help of medical grade 3d-printing resins one can produce very detailed customised chocolate maids in a very short time. So it is possible toturn around (from order to delivery) some small batches of individualised chocolade-bars in less than a day - big possibilities for small local Chocolatiers to meet the exclusive needs of their customers an gather a part of a totally virgin market. The presentation will show step by step how to produce this kind of maids.  

Tom Krause, igus GmbH - Application example: Customer-specific lubricated and maintenance-free wear parts produced by 3D printers

2014 - now  igus: Product manager iglidur Tribofilament (3d-printable bearing-materials)

2009 - 2014  igus: Research engineer bearings

2011 - 2013 Studies of business administration (MBA) - part-time

2004 - 2008 Studies of Mechanical Engineering (Dipl. Ing. FH)

His presentation:

igus developed bearing-materials which are process-able with different 3d-printing methods (FDM, SLS). Wearparts that are produced by 3D-printing with these materials have similar wear-characteristics than with conventional methods manufactured bearings.

That is why 3d-printed wear-parts are already used in all kinds of machinery manufacture industries; at series from up to 1000 pieces and also single pieces for special purpose machinery manufacture.

Dr. Ing. Andreas Pelz - Development of tailor-made materials for Additive Manufacturing

Dr. A. Pelz started its AM-related powder business 2 years ago in order to bring its knowledge and experience about metal powders into the AM-industry. Before this, he worked for 10 years as Leader of an R&D Department within a powdermetallurgical orientated company. During this period he worked on and finished his PhD thesis which investigated the metal powder atomisation process in detail.

His presentation:

This presentation focuses on metal powder materials. As introduction a general overview on metal powders and its production methods is given. From the manigfold possibilities of metal powder production the most promising ones will be bespoken in more detail and put into relation to the requests on their applied materials from users of AM-technology. An example on an general approach when dealing with new materials for lasermelting processes will be given at the end of the presentation.

Dr Annika Wilhelmson works as Key Account Manager at VTT Salutions for natural resources and environment, where she is responsible for sales to the food and beverage sector. She has a PhD from Helsinki University of Technology (now Aalto University) in bioprocess engineering. Her scientific background is in cereals, malting and brewing research. Through her work as Key Account Manager, she is also well-networked with the global food and beverage industry. 

Her presentation:

Today's consumer expects healthy, nutritious food with added elementssuch as design, pleasure and even playfulness. Self-production would enable customisation in addition to these. 3D printing technology offers new opportunities to meet such expectations. ln its initial trials, VTTtested starch and cellulose-based materials for 3D food prototypes. lt is also working on printability of protein concentrates of both plant and dairy origin. Texture is an important driver of the taste perception of many food products, and is behind many successful innovations. Brands are creatively combining textures with features such as crispy inclusions, softcentres and extra-crunchy toppings. 3D printing technology will enable the layer-by-layer manufacture of various structures, from crispy to softgels that produce a distinctive mouthfeel. 3D food printing is an ernergingand developing technology, with great potential for providing customised nutrition in a resource efficientway. 

Dr. Thomas Wimmer, Wacker Chemie AG - Customized chewing gum and bubble gum made by 3D printing

Dr. Thomas Wimmer studied chemistry at the Technical University of Munich. He holds a PhD in inorganic chemistry.

Work experience:

2003 to present:   Technical service and innovation lab manager at Wacker Chemie AG

2001 - 2003:       Sales and marketing for PVAc at Wacker Chemie AG

1993 -  2001:      Business development for cyclodextrins at Wacker Chemie AG

1990 - 1993:       Research and Development at Consortium für elektrochem. Industrie GmbH

His presentation:

Wacker Chemie AG is a leading global supplier of vinyl acetate based polymers which are widely used as an ingredient for the manufacturing of gum base. Additive manufacturing is a new technology where complex solid forms are build up layer by layer. Various printing concepts are meanwhile developed also for the food industry. Here we report about 3D printed chewing gum. With an optimized formulation edible and customized objects can be printed using a single head extruder.
