Laser-induced forward transfer of high-viscosity silver pastes

- Study of LIFT of high viscosity micron-sized silver paste using ns-pulsed lasers.
- Time-resolved imaging experiments illuminate the flow dynamics.
- Different regimes are observed in terms of process parameters.
- Continuous and stable pillar connecting donor and acceptor substrates isobserved.
- Concrete-dot transfer is the most useful regime for printing high aspect-ratio dots.
