Abstract: This study investigates the application of femtosecond laser-induced forward transfer (fs-LIFT) in the precise micropatterning of Platinum. Ultrashort pulsed lasers offer remarkable control in material processing, enabling the fabrication of microstructures with minimal thermal impact. Leveraging these capabilities, fs-LIFT has emerged as a powerful tool for depositing a diverse range of materials, including metals, semiconductors, and biomaterials, while preserving their intrinsic properties. This study focuses on optimizing key parameters, such as the number of laser pulses, pulse energy, and incubation effects, to enhance the Platinum transfer process and minimize collateral damage. Special attention is given to the production of platinum nanoparticles (PtNPs), valued for their applications in fuel cells and electronics. By describing the influence of these parameters, this research aims to refine the fs-LIFT process for producing high-quality microstructures, providing insights for advanced manufacturing in microdevices, sensors, and other components requiring precise control of printing materials, avoiding thermal degradation.
