Abstract:
Laser-induced forward transfer (LIFT) printing uniquely enables localized deposition of nanoparticle pastes onto target substrates.
The extent of its versatility hinges upon the availability of nanoparticle inks that align with the capabilities of the printing device.
Given the inherent distinctions among various devices attributed to differences in laser types (continuous-wave or pulsed), laser
energy profiles, and adaptable wavelengths, ink formulation and the LIFT printing processes are frequently disjointed, which
results in a lengthy optimization cycle. Significantly expedited optimization cycles could be achieved if LIFT performance of an
ink could be tested on-site of the ink developer. This localization empowers ink developers to tailor inks precisely to specific usage
scenarios by promptly adjusting parameters such as particle size, viscosity, and surface properties. This paper presents a dedicated
LIFT device that focuses on fine-tuning ink characteristics and provides insights into the construction to allow other interested
researchers to build similar low-cost, user-friendly setups.
