XTPL Ultra-Precise Deposition


“At Laser Zentrum Hannover, we were looking for a highly viscous conductive ink for our micro-dispensing setup with very small nozzles (<10 µm aperture). The XTPL Ag Nanopaste CL85 has proven very effective for our applications, where we aim to print fine structures measuring less than 10 µm. With XTPL Ag Nanopaste CL85 we are able to achieve long printing times without any interruptions.”

“With Ag Nanopaste CL85 we are able to improve printing resolution with respect to other inks with high solid content and the surface of the obtained printed patterns is exceptionally smooth.”


Prof. Juan Marcos Fernández-Pradas, MIND Research Group (Micro and Nanotechnology and Nanoscopies for Electronic and Electrophotonic Devices), University of Barcelona, Spain
