Holst Centre and AMSYSTEMS Center showcase latest developments in flexible & printed electronics at IDTechEx show! USA

Eindhoven (NL) / Santa Clara (CA, USA), November 14th, 2017 – On November 15-16, 2017, Holst Centre, an open innovation initiative of imec and TNO, and AMSYSTEMS Center, a joint innovation center of TNO and the High Tech Systems Center of Eindhoven University of Technology, will demonstrate the latest developments in printed and flexible electronics at the IDTechEx Show! at the Santa Clara Convention Center in California, USA.  

Holst Centre is at the forefront of the development of flexible, printed electronics, that can be embedded directly into fabrics, plastics and construction materials to create systems that conform to our bodies, the surroundings of our daily life including consumer products, interiors and transport vehicles.

One of the topics Holst Centre focusses on is in-mold electronics (IME) with complex 3D shapes by thermoforming or injection molding processes. By combining printed electronics with dedicated materials, designs and components, and carefully tuning thermal and pressure stability, Holst Centre is able to produce so called smart skins. Senior Scientist Dr Margreet de Kok will explain more about this technology, specifically focused on Automotive applications, in her lecture at the IDTechEx Show! on November 15th.

The AMSYSTEMS Center is dedicated to developing next generation additive manufacturing  production equipment for smart, personalized and multi-functional products. The AMSYSTEMS Center targets high-tech applications, 3D printed electronic devices, and 3D printed food and healthcare applications, with spin-off to other markets that require personalized, on-demand manufacturing.

Dr Joris Remmers, Associate Professor Composite Materials at the Eindhoven University of Technology and connected to the AMSYSTEMS Center, is scheduled to present at the show on November 16th. In his lecture, titled: ‘Towards, First Time Right Production of Multi-Material 3D Printed Products’, he will focus on the unravelling of the micro-mechanical behavior of printed materials and their interfaces as a function of the printing conditions.

For abstracts, timing and registration for both lectures please consult the dedicated IDTechEx website.

Various functional demonstrators of AMSYSTEMS Center and Holst Centre’s cutting edge technologies, as well as a BigRep Studio 3D printing unit, will be on display at the joint booth (M24) at the IDTechEx Show! at the Santa Clara Convention Center in California, USA.


In the Spotlight: Dolf Klomp

Meet our first PhD student Dolf Klomp on 3D food printing. After working at Nuon/Helianthos in flexible solar cells Dolf joined the TNO department of Equipment for Additive Manufacturing as a Physics Development Engineer in November 2011. The last two years Dolf has been involved in 3D food printing. With this background and his keen interest in new technology Dolf has started his PhD research on 3D food printing in December last year.

At that moment TNO and TU/e HTSC had joined forces in the field of 3D-print equipment in the combined AMSYSTEMS CenterNext to his PhD research he is also working on the development of the Next Generation 3D Food Printer that is being developed by AMSYSTEMS Center. He comprises his PhD position at the Eindhoven University of Technology, department Mechanical Engineering, research group Polymer Technology.

Powder flow behavior
His research topic entails the creation of a multi-material powder bed for 3D food printing. Dolf’s focus is on the prediction of powder flow behavior during the creation of a multi-material powder bed by creating a simulation program. His approach on this topic is twofold. First, it is to create a multi-material powder bed micro dosing with ultrasonic vibrating nozzle. This will foresee allowing for the accurate dispensing of powder voxels. Dolf will start an experimental setup with several selected model powders for the validation of the concept. Second Dolf will set up a simulation of powder flow. A discrete element method (DEM) program will be written for the prediction how different food powders behave during deposition and the subsequent 3D printing processes. The experimental setup will be used for validation of the simulation.

Characterize forces and implementation
It will be a challenge to characterize all forces and implementation. “Specifically the validation of the forces based on experimental bulk data”, emphasizes Dolf. “Furthermore, since DEM is very computational intensive it will be also not easy to keep the calculation time to an acceptable level.” A whole set of forces are interacting on each particle in granular matter. These forces range from the contact forces such as elastic forces, friction forces, damping forces and adhesive and cohesive forces at the contact area to non-contact forces such as the Van Der Waals forces, electrostatic forces, capillary forces due to water bridging, friction and gravity. All these forces have several different implementation models and spheres of influence, determining the needed level of implementation detail and which forces don’t have significant contributions will be challenging. Certainly since using bulk material properties as particle surface properties might be questionable. Experimental verification of the DEM model will be challenging since mostly only experimental bulk data can be measured as opposed to the actual forces implemented in the model. There is a risk that there are fewer experimental well defined and understood parameters than the parameters in the model leading to an under defined problem which makes validation challenging.

The step towards multi-materials food printing
3D food printing is a novel technique of producing food with a unique range of benefits. One can think of personalized nutrition where nutritional needs are tailored to your specific person and not just broadly, but on a day-to-day basis in combination with health apps monitoring your eating and sporting habits. A step further, and of great interest for nursing

 

“Fresh produce, less waste and a more natural diet”

 

homes and hospitals, is medical nutrition where not only nutria needs are more important but one can also think of incorporating drugs and drugs delivery systems. It also opens up a whole new range of possible products for industry since limitation on the shape of a product and the ingredient used are lessened through 3D food printing. Since 3D printing in itself is an on-demand technology the whole distribution of food substances can change leading to more fresh produce, less waste and a more natural diet.

In the Spotlight: Jeroen Knippenberg

Meet our new PhD student Jeroen Knippenberg at AMSYSTEMS Center. During his mechanical engineering bachelor and master studies at the TU/e, he developed a passion for the engineering of high tech materials in challenging environments. This passion has enabled him to work for example on lightweight carbon fiber composite structures in racing cars and from 1 July 2017 in the challenging field of industrial additive manufacturing. Within this field Jeroen sees an opportunity to enhance his skills as an engineer and researcher while contributing to the advancement of the industrial applicability of additive manufacturing.

For the upcoming 4 years Jeroen will be focusing his fundamental research, which is part of the European Hyb-Man project, on hybrid 3D manufacturing methods for multi-material products with integrated electronic components. The goal of the methods is to enable flexible first time right production of smart systems for lighting and automotive products. “Currently the combination of multiple materials and multiple functionalities into a single AM product significantly increases the complexity of the production process,” Jeroen explains. “To be able to manufacture such products first-time-right,” Jeroen continues, “a thorough understanding of the relation between process parameters on one hand and intrinsic material properties and functionalities on the other hand is required.” For example it is important to understand the relation between sintering temperature of a conductive track and the corresponding electrical resistance. The possible track sintering temperature can be limited because of the use of other materials less resistant to temperature in the hybrid product, while the track resistance specification still has to be met. The research of Jeroen is to get this understanding by providing design rules for the hybrid 3D manufacturing process, based on the obtained insight in the process.

 

The goal of the methods is to enable flexible first time right production of smart systems”

 

Approach and challenges
His research starts with identifying individual input-output relations between process parameters and material properties. Then the relations will be studied by various numerical models and experimental material characterization. These models, each representing a small part of the production process, will be combined in a design structure matrix (DSM) and system optimization techniques will be used to identify the opportunities and constraints in the hybrid manufacturing process. Jeroen foresees a challenge in creating suitable numerical models for the additive manufacturing process, as the models are generally new for this industry. Another challenge is the effort of creating an overview in the large parameter space with these different relations. Two challenges that Jeroen is eager to take up.

Cost effectiveness and meeting rapid changing requirement
Jeroen hopes successfully to develop a 3D hybrid manufacturing process that allows local production of highly personalized electronic products without the need for product specific tooling and large stock of parts or products. “Advantages of such process is the cost effectiveness of the production of the small series and rapid changing in requirements from the market can be accounted,” Jeroen says.

Kick-off Hyb-Man project

After a successful kick-off meeting in April 2017 the Hyb-Man project has started, with the goal to develop hybrid 3D manufacturing methods to enable flexible first time right production of smart systems for lighting and automotive products.

Together with 11 partners from Germany and the Netherlands we will develop and integrate technologies for additive manufacturing, 3D electrical structures, 3D assembly and interconnect. First time right production will be achieved by creating design rules based on understanding of product-process relationships and by developing in-line testing and quality monitoring as integral part of the complete production chain. In parallel we will develop two innovative product cases covering different applications and sectors (LED luminaires, automotive adaptive sensors) to demonstrate the hybrid 3D manufacturing approach.

Highly flexible
The resulting manufacturing process is highly flexible through the removal of product specific tooling, no large stock of parts or products, local production and form freedom in production. This results in substantial business benefits, such as: faster response to changes in the market, cost effective manufacturing of small series and customer centric solutions, and new product designs offering improved functionality and new form factors.

The project duration is 3 years, with a total effort of 56 person years from 11 partners: Philips Lighting, TNO, Bosch, Fraunhofer IFAM, Reden, VSL, Henkel, Technolution, Neotech, Xenon and Eindhoven University of Technology.

In the spotlight: Thomas Hafkamp

Thomas Hafkamp is one of the first doctoral students who has begun at the AMSYSTEMS Center. Following his TU/e Master at the department of Mechanical Engineering (specializing in Control Systems Technology, graduating in the design principles group), he began his PhD research for the AMSYSTEMS Center on 1 March 2016.

“AM equipment has to be scaled up to larger product formats and higher product quality if the needs of high-tech industry are to be met. To be able to achieve this we have to investigate modeling, measurement and control in industrial AM processes,” Thomas explains. “The AMSYSTEMS Center has defined two PhD assignments for the additive production of high-grade ceramic products, each concentrated on one of these three aspects,” Thomas continues. The third assignment is focused on fluid dynamics.

Tackle challenges
“My research is geared to the control side of the print process and the aim of my research is to develop new equipment concepts and integrated control architectures.” The challenge faced by Thomas in his research is the simultaneous scaling up of the three characteristics of AM equipment: from its current small format to industrial scale, to boost the product quality and reproducibility, and to increase production speed. “To further develop AM technology new concepts need to be generated on the basis of a holistic, systematic approach that is able to tackle these challenges (scalability, quality, productivity) at one and the same time,” Thomas clarifies.

Cross-fertilization
The collaboration between TNO and TU/e HTSC is already very noticeable and will become ever more evident. “Given the powerful multidisciplinary nature of additive manufacturing, there is plenty of potential for cross-fertilization between and perhaps even within the two organizations. It’s something I already see happening during the regular meetings of the AMSYSTEMS Center.”
