WHAT IS OUR SOLUTION? Nanoprinting system designed by XTPL makes it possible to precisely apply to the surface a special ink formulated for this purpose in the company s laboratories. Under the influence of an external electric field, the nanoparticles in the ink create conductive lines according to the specified parameters. As such, the thickness of the individual lines, their length and the distance between them all vary depending on a specific application. XTPL creates complex numerical models and uses advanced characteristics of nanoink and printed lines. This allows the company to constantly optimize its innovative technology and adapt the process to different implementation requirements. HOW WE ACHIEVE RESULTS?

NANOPRINTING human hair nanometric conductive line XTPL Ag Line ultra-precise printing enables achieving flexible, transparent, cost efficient & highly conductive lines, even 400 times thinner than a human hair nanoprinting will soon revolutionise sectors such as: printed electronics, solar cells, touch screens, wearable electronics, smart packaging, automotive, biosensors, medical devices, anti-counterfeiting & open defect repair TECHNOLOGY CORE PRINTING HEAD The heart of the XTPL technology is designed by company s specialists innovative printing head. It operates on the basis of a unique algorithm & enables ultraprecise application of the ink with nanoparticles and formation of conductive lines. This revolutionary construction is subject to modifications that allow for dedicated application and optimization for a given application field. Basing on the customers requirements the company is providing versions adapted to obtain outstanding results, i.e.: pressure version offering versatile method of dispensing that functions across a wide range of viscosities, it ensures fine and repeatable dots and lines and is suitable for a wide range of applications, from inline to batch dispensing to open defect repair process, whole construction is fully controlled by XTPL own electronics; capillary version specially designed for ultraprecise and demanding applications, small, robust and easy scalable device that allows for dispensing of the XTPL ink and formulation of electrical signal at the same time, it is used to create submicron & nanometric conductive lines with very small amount of ink (processes where minimum contamination is required - washing & drying no longer needed); multi-electrode version signal electro-mechanic module controlled by comprehensive & pioneering algorithm created by XTPL as the answer to marked demand for high printing density, allows for creating simultaneously two or more lines, main advantage of this solution is increased speed of printing due to multiplication of electrodes in one compact feature.

PRINTING PROCESS During the process of line formation, the printing head deposits a properly formulated ink - nanoparticles in a mixture of solvents - on a non-conductive substrate, in example such as glass or flexible foil. An external alternating electric field causes nanoparticles to assemble in a clearly defined and controlled way to form a line. The process takes place between a stationary and movable electrode. PROPERTIES OF THE LINES Functionality of the lines: electrically conductive, optically, biologically and chemically active Nanomaterials: metallic & semiconductor Line width: from 100 nm to 15 μm Line length: up to 25 cm range Aspect ratio: 1, in the single run of the printing head Very low voltage applied: 5-30 V Substrates: i.e. glass, Kapton, PEN, PC, PDMS, PET Movable electrode: guides the formation of the line, which becomes an extension of the stationary electrode. Finally, the printing head short-circuits with a metallic pad, and the line connects to the pad while the printing head takes in an excess ink. Resistance: 2 Ω /μm (for the line with the thickness of 1 μm), proof of concept manufactured featuring up to 20-40% bulk Ag (thickness 100-400 nm)

XTPL PRINTED LINES The feature size of printed structures is one of the key parameters in XTPL technology. The width of structures obtained using our method can reach even below 100 nm. What makes the XTPL technology unique is the possibility to create lines with a width-to-height aspect ratio close to 1 in a single pass of the printing head. Reducing the width of the printed structures is important as among others - it increases the transparency of conductive films. In our method, it is possible to adjust the properties of the conductive lines by changing: the amplitude, shape and frequency of the electrical signal; the physicochemical properties of the ink; and finally the size, distribution and shape of nanoparticles.
