Challenges and oportunities applying disruptive technologies for direct digital manufacturing based on functional materials and 2D/3D printing technologies
The term disruptive technologies was introduced by C.M. Christensen and J. Bower in their 1995 article Disruptive Technologies: Catching the Wave, since then it has being used in business and technology literature to describe innovations that improve a product or service in ways that the market does not expect, typically first by designing for a different set of consumers in a new market and later by lowering prices in the existing market. In the area of products manufacturing, a technology is considered disruptive when its utilization reduces product development times and cost as well as for addressing the need for customization, increased product quality, and faster response to the market.
One of the most recent and promising examples of disruptive technologies being introduced in the last 20 years in manufacturing processes is the use of printing technologies, that are no longer applied just for reproducing text and images with ink on paper or another support, but it became a method for what is denominated an Additive Manufacturing Technology. Additive manufacturing is the creation of various objects by adding successive layers of materials to create a product, for example an electronic component for printed electronics or a 3D device for rapid prototyping.
This technological revolution that has emerged after a long journey of worldwide R&D efforts is a perfect example of re-engineering and simplification of processes, which is characterized by its unique multidisciplinary nature of intimate relation between the request for sophisticated functional materials in general (and nano-materials in particular) with new or improved printing technologies. The maturation of this multidisciplinary approach has become the upright pillars for a new age of commercially available direct digital manufacturing systems (i.e. 3D printers), which have changed the workflow for the design and implementation of manufacturing processes.
During my talk, I will present an overview of this new technological world, while emphasizing the requirements and challenges for the development, application and commercialization of direct digital manufacturing technologies like inkjet printing systems, for two and three dimensions and the future trends for the continuation of this technological revolution.
Introductory Presentation of Dr Claudio Rottman
Dr Claudio Rottman studied chemistry at the Hebrew University of Jerusalem until 1998 where he received his PhD degree for his thesis in the application of sol-gel technology for the development of optical sensors. After finishing his studies Dr Rottman became Chief Chemist of the start-up company Sol-Gel Technologies Ltd., where he applied his knowledge in the sol-gel process for the development of drug delivery systems based on silica microencapsulation of active components and drugs for cosmetics and pharma.
At the beginning of 2004 he become the R&D Laboratory Manager of Cima Nanotech Ltd., where he lead the development of inkjet conductive inks and nanoparticles self-assembling technologies, for printed electronics applications based on nano-metal particles.
Since 2007 Dr Rottman leaded several materials development projects in the areas of nanomaterials, polymeric coatings and special functional inks in the frame of multidisciplinary projects for printed electronics, as the Chemistry Manager for the R&D Division of Orbotech LTD. and at The New Technologies Division in the 3D Inkjet Printing Company Objet Geometries Ltd. (today Stratasys Ltd.)
Today Dr Rottman holds the position of Materials and Technology Development Manager at the company Highcon Systems Ltd. that developed a new digital machine for die cutting and creasing of folding cardboards. Dr Rottman is also a co-founder and owner of Ujett Digital Printing Ltd. which is a functional materials development and consulting company for direct digital manufacturing technologies.
Dr Rottman is the owner of more than 30 patents and scientific publications related to the different areas in which he has being active during his professional career.
