Abstract

The need for smaller and more efficient printed electronics is on the rise, and while nanoparticles are the clear next step in realizing this goal due to their unique properties that cannot be detected in their bulk form, research on how to use them effectively is still in its early stages. Through a manufacturing convergence approach, we aim to develop a system that can process raw materials all the way through to the final application. In this study, we suggest modifying the setup design of an ultrafast pulsed laser system to demonstrate both the synthesis of Tin Oxide (SnO2) nanoparticles from bulk metal through Pulse Laser Ablation-in Liquid (PLA-L) and the printing of said nanoparticles utilizing the Laser Induced Forward Transfer (LIFT) method. The colloidal solution and printed outputs were tailored by adjusting not only the laser parameters but also the process parameters of both PLA and LIFT respectively. Experimental results show great potential for both synthesizing and printing the nanoparticles using a single laser system. This work establishes the single system concept, in which a single laser system can convert bulk metal into nanoparticles-based applications without the need for additional processing from other machines/systems, allowing for highly customizable prints with reduced lead times.
