09:50 - 10:00 Introduction by Peter Buttiens, ESMA
10:00 - 10:30 KEYNOTE: Fine line printing of functional inks for automotive applications
Prof. Tim Claypole (bio) | Swansea University
There is a need for some automotive applications to print networks of highly conductive fine tracks onto large flexible substrates. This presentation provides an insight into the mechanisms of ink transfer that determine the quality of the printed features. Printed tracks of sub 25µm width have been demonstrated using high resolution metallic meshes. The ability to achieve high resolution features by screen printing is determined by the interactions between ink rheology, mesh, screen emulsion and printing conditions. Investigation using advanced rheological techniques to study printability provide a rigorous basis for better prediction, control and consistency. Silver conductive inks have been characterised by a combination of rheological measures, including constant shear, Small Amplitude Oscillatory Shear (SAOS) and Controlled Stress Parallel Superposition (CSPS).
10:30 - 11:00 Inks for smart surfaces and in-mould electronics
Dr Fabian Gyger (bio) | Elantas
In-mould-decoration or film-insert-moulding (IMD/FIM) based on screen printing and high pressure forming have been around for a while now. Through printed electronics, touch functions can be integrated directly into the plastic part creating a “smart surface.” These smart surfaces are a big market trend for example in automotive interiors or white goods. The applied process demands a robust and reliable conductive ink system able to withstand the high temperature and pressure of thermoforming and moulding. Alongside the smartness of the surface achieved through printed electronics, the surface has to be seamless as well. This means graphical issues have also to be taken into consideration. At ELANTAS Europe we have applied ALTANA’s expertise in the field of IMD and combined it with our knowledge of printed electronics. Thus, we have developed a very capable ink system addressing aforementioned problems. This talk will provide you with answers to questions regarding the production of smart surfaces using the IMD/FIM process.
11:00 - 11:30 Inkjet in coatings and complex shapes: Technologies and processes
Debbie Thorp (bio) | GIS
Inkjet is most often considered as a graphics printing technology for flat surfaces like paper and film, but it is perhaps more accurate to consider it as a highly flexible deposition technology capable of jetting inks or functional fluids onto a growing range of substrates and surfaces. Advances in printhead technology, combined with advances in software, mean that inkjet can be used effectively in applications and environments that were not possible before. This presentation will focus on the capability of inkjet technology in industrial coating and decorative manufacturing applications.
11:30 - 12:00 Coffee break and tabletop networking
12:00 - 12:30 High resolution silk screen print form imaging for exacting applications
Dr Gérard Rich (bio) | Lüscher
Lüscher continues to invest in technology building blocks to enhance silk screen print forms production to satisfy evolving and demanding needs of the industry. One of these elements is the high-resolution imaging. This implies that the screen is held in position accurately and in perfect registration. Application in demanding segments request imaging resolutions up to 10,160 dpi whereas the state of art in the industry is still below 2,540 dpi. The technology developed includes a software package that is user friendly and totally integrated to guarantee a high fidelity of reproduction of digital data (defined in the TIF file) on the screens and to allow for printing very fine graphics (30 to 40 microns lines as example) under perfectly mastered industrial conditions. The combination of high resolution, the associated software package and the accurate positioning opens new possibilities currently out of reach of standard imaging technology.
12:30 - 13:00 Make printhead jettability wider
Yoshinori Domae (bio) | Seiko
SII Printek Division within the Seiko Holdings Group has been working on industrial inkjet printheads since 2001. At AFIP 2019 we would like to focus on the limits of inkjet technology, following our results from several different approaches. When testing the latest printhead RC1536 we have aimed to confirm jetting direction, jetting distance and jettable fluid parameters. Basing on the figures achieved, we would like to let you consider the innovation possibilities of inkjet.
13:00 - 13:30 Advanced screen printing mesh in an industrial environment
Patrick Brunner (bio) | Sefar
The requirements of industrial screen printing are extremely high. Nothing succeeds without standardised production processes, precisely defined printing parameters, controlled process steps and – absolutely essential – most stringent reproducibility. Only when all these factors are optimised, it is possible to achieve exactly what your customers require in today‘s market: Competitive prices and quality. The key words? Low elongation, accurate, efficient, fast.
13:30 - 14:30 Lunch break and tabletop networking
14:30 - 15:00 KEYNOTE: Goodbye, membrane keyboard?
Martin Gehrig (bio) | Hoffmann+Krippner
Membrane keyboards have been the favourite solution in many applications since their development in the late 1970s. They are one of the most widely used operating elements in devices and machines because they have many advantages compared to normal keyboards: Almost every shape and size is possible, they are water proofed and easy to clean and they have a flat and robust design. But in the last few years capacitive touch systems are accepted in more and more devices because the equipment manufacturers want to have a modern user interface. This is reinforced by the fact that microcontrollers and displays are becoming cheaper and cheaper. So, the question is: Will the membrane keyboard have any future at all? Or do they have some unbeatable advantages over touchscreen solutions?/p>
15:00 - 15:30 aNIR-enabler for advanced functional printing applications
Dr Kai Bär (bio) | Adphos
Non-contact print and coating technologies, whether inkjet or atom jet or others are now developed and established widely in the graphical business. With the additional, partially demonstrated capabilities of the inks/coatings, an extreme potential for functional and wide range industrial printing is seen. But also mandatory and another driving factor for a successful market introduction here is the appropriate adaptable post printing process – the so called ink drying and fixation step. In this presentation, the NIR-technology, which is already widely established in graphical inkjet printing systems, is outlined and evaluated according the specific application requirements for functional and industrial printing/coating processes. Here beside the removal of the water or solvents, the mostly in addition thermal processing for the final function (e.g. conductivity), is needed. So thermal sintering and or curing has to be achieved, at elevated temperatures, but with low adjacent thermal stress on the substrates (e.g. plastics, textiles, composites). In addition, the required drying (thermal process) time and the resulting possible dryer system configuration is crucial for successful solutions on three-dimensinal components (direct print to shape). Several possible new applications are outlined.
15:30 - 16:00 The screen imaging process with different technologies for different applications
Oliver Leven (bio) | CST
The screen imaging process with different technologies for different applications. The screen imaging process needs to follow the specifications in relation to various characteristics. These specifications vary for different applications at different customers and with different local parameters. Therefore this process needs to be optimised for its unique customer and application case. Of course, it should always be at the highest resolution with the maximum speed and the lowest running costs. Moreover, the initial investment should be as low as possible and the accompanying costs for maintenance and consumables should be observed. Such factors need to be balanced in different ways for different applications and for the unique client situation. In this presentation we will look at a range of solutions with different configurations to match the individual client situation.

16:30pm - 17:00pm Automotive 2.0: From analogue dial to display and from plastic to cooltouch
Claudia Bauer (bio), Markus Rodrigo | Marabu (bio)
Digital development is on the rise in the field of speedometers in the automotive sector. Using the example of speedometer panels with enormous design potential and often applied in high-end screen printing. These functional ink layers are printed with the highest precision and harmoniously round off the component in the interior area. The demands placed on these ink layers are enormous in terms of resistance and properties of the subsequent assembly.
Haptic surface structures, gloss and matt effects are indispensable elements in the automotive interior industry. The current trend towards "cool touch" surfaces makes the use of aluminium instead of or in combination with plastic components indispensable. This means for the screen printed ink film it has to be formable, good surface hardness, high temperature and chemical resistance. Marabu currently devotes itself intensively to this topic and presents technical details regarding application and product selection.
17:00 - 17:30 Simplify screen printing: The importance of a perfect screen
Andreas Ferndriger (bio) | Grünig/SignTronic
Functional and industrial screen printing remains very competitive if screen printers follow simple rules. CtS direct exposing technology (replacing film) is a must as production steps are reduced tremendously. Automation and standardisation in stretching, coating and washing processes are indispensable to increase quality and lower costs.
17:30 - 18:00 KEYNOTE: Radiopaque 3D printing of patient specific phantoms: An inkjet application for patient safety in radiology and radiation therapy
Dr Paul Jahnke (bio) | PhantomX
Phantoms (test objects) allow repeated radiation exposure under standardised conditions without the challenges associated with human test subjects. Phantoms with simple geometric designs are widely used in radiology and radiation therapy for commissioning and consistency testing, but do not reflect clinical radiation exposure of patients. The purpose was to develop a method for 3D printing of realistic anthropomorphic phantoms representing individual patients. The developed technology uses inkjet technology together with radiopaque inks to print patient computed tomography images on paper. Processing of the printed stacks with paper-based 3D printing methods creates stable phantoms with the shape, size and attenuation properties of the original patient. Such patient phantoms allow highly detailed simulation of patient radiation exposure and provide novel opportunities for quality assurance, testing and improvement of radiation exposure in radiology and radiation therapy. An introduction to the background, an insight into the technology and key applications for low and high dose radiation exposure in radiology and radiation therapy will be presented.

09:00 - 09:30 KEYNOTE: Inkjet printing: Drawing its success story in electronic and bio-printing fields
Jérôme Mouly (bio) | Yole Développement
Inkjet printing has become an attractive technology for numerous industrial applications, from OLED displays to printed electronics, PCBs, and bio-printing. As a digital technology, inkjet printing offers high flexibility and cost-effective processes for precisely depositing conductive lines or dielectric materials on electronic devices. 2.5D inkjet printing revolution is underway with promises and challenges linked to printer production speed, ink formulation and printhead choice. The presentation will describe the potential of inkjet functional printing and which applications are driving its adoption from Yole Développement’s latest researches. It will describe the dynamic of the inkjet functional printing with market metrics for the next 5 years and the ecosystem of players setting-up from printhead to printers as well as end users with applications examples. Is inkjet building its success story drop by drop within 2.5D manufacturing?
09:30 - 10:00 IMD/FIM screen printing inks, adhesion promoters and protective lacquers for film insert molding technology
Dr Hans-Peter Erfurt (bio) | Proell
Screen printing ink with functional elements is the key for durable decorated plastics as in-between the compound and optionally top coat in case of film insert moulding. Requirements in adhesion and activation of layers are well understood, but new materials and more demanding specifications give reason for improvements and modifications of recipes. For example, enlargements in binder and pigmentation which cater for the needs of touch pad applications and even larger sizes of decorated parts, will be explained and demonstrated. Avoiding conductive pigments in decoration or balancing by recipe?
10:00 - 10:30 Advanced finishing solutions: A new era for market interaction
Germano Primi (bio) | Eptanova
World is looking for added value solutions and supplies to decorate, protect, ennoble and functionalise surfaces and goods. Such finishing propositions will increasingly require a smart technological portfolio management, to include and combine full ranges of industrial inks, coatings, specialties and other specific chemicals. Moreover, applications techniques, riding fast process innovation waves, will ask for radical redesign and integration. An industrial segment successful approach will therefore need to identify the relevant key players, then to set the proper conditions to let them work together to customer challenges. Finishing arena is moving to a new era! This presentation will show how to link key operational performances to key success factors in advanced finishing business cases.

11:00 - 11:30 How printed electronics is serving your everyday life?
Vincent Carniato (bio) | VFP
The cost-performance ratio makes printed electronics very attractive for certain applications and their development is additionally stimulated by the current mega-trend of integrating electronic components in “smart” objects. Organic electronics, printed, large area, flexible, are the key words in this area, each referring to specific technical and physical characteristics. Organic characterises electronic components made of organic materials, composed of carbon and hydrogen. Large surface refers to the production techniques used to produce components in large quantities and at low cost: roll-to-roll or foil-to-foil production. Printed describes the traditional filing methods not exclusive to the electronics industry. Flexible reflects the ability to produce flexible electronic systems that integrate with all types of flexible substrates. The numerous applications envisaged make it a major field of research. The dynamism of investments made in Europe, the progress made in production techniques and the materials used suggest the development of this new industrial sector in the world.
11:30 - 12:00 Digital fabrication of flexible electronics
Dr Fernando Cortes Salazar (bio) | Agfa
Inkjet printing is recognised by the industry to be the most fitting technology for both prototyping and industrial production of printed electronics as it delivers unparalleled precision in ink deposition. Additionally, inkjet printing brings improved cost efficiency thanks to minimising waste, faster turn-around in design and shorter lead times. From the early days of inkjet technology, Agfa-Gevaert has been pushing boundaries to enable the industrial use of inkjet printing in graphical applications, as well as for the development of cutting-edge materials for printed electronics and PCB technology. At AFIP 2019, Agfa will showcase the combination of conductive and dielectric inkjet inks for membrane switch sensors fabrication and explain how to overcome technological challenges (e.g. material and post-processing compatibility) required to accomplish this milestone.
12:00 - 12:30 Mesh beyond the state-of-the-art
Peter Fleischer (bio) | PVF
The state-of-the-art mesh in Europe is Polyester mesh down to 27µm thread diameter and stainless steel wire mesh down to 16µm wire diameter. Both with a certain grade of strength, elongation, dimensional stability and a certain balance of strength/tension in warp and weft direction. A mesh “beyond state-of-the-art “ is characterised by superior strength, elongation, dimensional stability and balance of strength/tension in warp and weft direction. The Polyester mesh is made with bi-conjugated threads down to 24µm thread diameter. The high-tech Polyarylate mesh is made with threads down to 20µm thread diameter showing no yielding point. The stainless steel wire mesh is made with triple melted stainless steel wires down to 13µm wire diameter and up to 3200 N/mm² strength. Last but not least, the tungsten wire mesh is made with tungsten wires down to 11µm wire diameter and a strength up to 3600 N/mm² – showing no yielding point. It provides for finer lines, smaller dots, and the most homogeneous layers along with the highest dimensional accuracy prints and long screen lifetime.

13:30 - 14:00 From 2D to 3D printed electronics: Two industrial approaches for integrating electronics in 3D objects
Claudia Delgado Simao (bio) | Eurecat
In the last years, additive manufacturing has gained a tremendous interest for integrating electronics in 3D pieces. In this talk we focus on two different approaches to preparing functional 3D plastic pieces, by application of common planar printing techniques. The first approach deals with the use of 2D printed plastic foils via screen or inkjet-printed electronics for posterior thermoforming. Thermoforming electronics is also compatible with In Mold Electronics, a robust high throughput manufacturing for achieving integrated lightweight electronics in plastic parts. Secondly, direct printing over 3D piece using a printhead on a robotic 6-axis arm allows to prepare printed circuits without the constraints of material requirements for thermoforming or printing. The results of the two approaches are discussed and compared.
14:00 - 14:30 Waveforms for industrial inkjet printheads
Matthew Pullen (bio) | Meteor Inkjet
Printheads are fundamental components of all industrial inkjet systems and the choice of printhead driving waveform can make the difference between dazzling success and dismal failure. The subject of waveforms can seem complex and baffling given the myriad of printhead types, all driven in unique ways, together with a seemingly infinite variety of fluids. What is a waveform? How is it developed? Why are there so many different printhead implementations? Can a waveform be optimised for a specific ink/printhead combination? How do unusual fluids impact the choice of printhead and waveform? The answers to these questions and more are particularly relevant in the functional print space.
14:30 - 15:00 Exentis 3D Mass Customization®: True industrialized additive manufacturing
Srdan Vasic (bio) | Industrial Print Solutions / Exentis
Based on high-developed screen printing technologies the Exentis-Group is building a 3D mass customisation platform to produce industrial parts. These functional parts can be based on ceramic, metal, silicate, organic or biomaterials. The presentation focuses on applications such as printed filters, sensors or fine metal parts. It discusses the challenges screen printing faces in the realisation of freeform-shaped designs.

15:30 - 16:00 KEYNOTE: How to utilise printed inks and electronics in healthcare – a case study
Jesper Hassel (bio) | Mevia
Adherence to medication, not taking your pills as prescribed, is one of the biggest challenges in medical treatments, simply because pills do not work in people who do not take them. The presentation will introduce the challenges of medication adherence and how Mevia has tackled the problem by using printed electronics. This has been done in settings as diverse as home care, pharmacies and in direct collaboration with pharmaceutical companies both within human and animal health. Our solutions consist of monitoring when a patient has removed a pill from a package, be that a pill blister, pill dispenser or pill pack.
16:00 - 16:30 PowerHeat! The power of NIR drying in the functional printing
Ralf Martin Eckert (bio) | Lambda Technology
The presentation shows the interaction between media and ink in the application process, as well as the connection between energy input and drying processes in the protection layers or pottants and tow component systems. It explains how drying should be built in different environments and explain the technical benefits of NIR (Near-infrared) in the complete spectrum of drying processes. The integration possibilities of NIR are shown, together with the high energy saving possibilities of this technology.
16:30 - 16:45 Precise warp determination and measurement on silk screen sieves. Thread counting vs. mesh measurement
Jürgen Brag (bio) | OSIF
The presentation is about the benefits of in-production measurement of printing screen distortion by immediate provision of warpage data. The determination on screen usability is therefore enabled directly prior to employment respectively set up for the next print job. Common and often significant delays for initial (printed) sample approvals are falling away; the overall productivity of the screen print processes is increased. The WarpInspector system provides accuracy of ≤ 10 µm (at common diagonals of the print layout) at a standard deviation σ of ≤ 1.5 µm. Digital and mobile thread counting is the second topic of the presentation – the MeshC system. Requiring just a low-budget camera and a less than ordinary laptop computer, the efficient and capable analysis software by OSIF provides mesh count data (per inch or cm, separated by weft and warp orientation) without cumbersome prerequisites, error-free and immediately. Typical employment scenarios for printing screen mesh checks are incoming (outgoing) inspection, production environment, after cleaning/washing, before placing back to or removing from stock.
16:45 - 17:00 Advancements in inkjet technology for material deposition for research and manufacturing
Scott Liniger (bio) | Matthews International
Inkjet technology advances, providing greater opportunities for prototyping, manufacturing, and materials dispensing. This presentation covers the capabilities inkjet technologies provide, as well as explores where this technology is heading. Multi-head inkjet systems provide tri-dimensional printhead positioning for accurate drop placement and deposition. Multi-head systems are ideal for configurable 3D materials deposition, as well as for printed electronics, biology, and other applications requiring a high degree of material placement accuracy. For example, one customer is using a multi-head system as an additive manufacturing system, depositing a layer of material, curing, depositing another, different layer of material, curing, and so on, to produce high resolution specialty optics. While still in the developmental phase, this system can be easily scaled up for manufacturing. Inkjet technology is proving an ideal development tool for materials deposition in a variety of markets and applications where a high degree of analytical analysis and jetting accuracy is required.
