“The XTPL’s ability to directly deposit (in a mask-less approach) electrically conductive structures in the minimum feature size range of 1.5 – 10 micrometers is unique. In my view the XTPL’s ultra-precise deposition technology offers truly unique properties, which are an excellent fit to the future needs in the field of printable high-resolution and foldable OLED displays.“

Director of IGM at University of Stuttgart

“Our research revolves around the development of high-performance printed electronics and sensing systems on large area flexible substrates. We used these printed systems to develop flexible electronic skin (eSkin) and explore its application in healthcare, wearable systems and robotics. In our projects we also use micro/nanofabrication tools and align them with processing on flexible substrates. We decided to purchase the Delta Printing System for our labs, after performing initial tests with the team at XTPL over the last several months. This appears to be a great enabling tools and we are looking forward to including it in our daily research work.”

Prof. Ravinder Dahiya
The Leader of the BEST research group at the University of Glasgow

“One of the focus areas for our research is the development of assistive technologies for the production of a modern class of biosensors, which are sought after by global industrial clients and which must satisfy their current requirements, including in terms of environmental protection. Another aspect is the ability to micro -fabricate – or build micrometric devices and components. Microfabrication of bioelectronic devices for detecting a single molecule requires the capability of applying ultra-thin conductive structures with a width and pitch below 1 micrometer, as well as with an appropriate viscosity index. Until now, our University did not have a proper system for this purpose – no such solution was available on a global scale. Once we got to know the XTPL technology and its unique capabilities, we decided to buy the Delta Printing System. This investment will definitely increase the potential of the Smart Devices laboratory at the DII. Our research goal is to develop ultra-sensitive organic printed biosensors integrated on three-dimensional conformable and flexible substrates that will be biodegradable after use, a solution which we would like to implement for our commercial partners. The biosensors will be intended primarily for the biomedical industry. We would like to cooperate with XTPL for a longer period to reach this goal”

Prof. Fabrizio Torricelli
University of Brescia

“We became very much interested in the UPD method developed by the XTPL team. We first learned about it and the Delta Printing System at the ISFOE conference series in 2021. After we had the opportunity to find out about the capabilities of the method, we decided that the device would be a great tool for our scientists who are working on new technologies for sensor, photovoltaic and optoelectronic solutions. We are not going to stop at the academic research phase: moving forward, we’re planning to implement the results in real-life applications at our industrial partners who have been cooperating with our institute for a long time. We’re very happy that soon we’ll be able to incorporate the XTPL technology into our work.”

Head of the Hybrid Devices group and expert in organic semiconductors and printed semiconductor devices., Humboldt University of Berlin

“This unique printer will be used to conduct research and development in photonics. One of the challenges in this area is the advanced micro-integration of photonic features. In this area we see great potential for the Delta Printing System in the context of our work, but also generally in photonic technologies that are growing rapidly in scientific and commercial terms. Our cooperation with XTPL is also an excellent example of multidimensional mutual benefits that can be achieved by closely cooperating research units and technology companies.”
