An experiment research on the laser induced forward transfer of sodium alginate solution was carried out, and the effect of laser pulse energy, spot diameter, thickness of titanium layer and the mass fraction of sodium alginate solution on experiments of droplet diameter and surface morphology was discussed. The experimental results showed that when the spot diameter was 100 μm, the diameter of droplets was smaller, and the surface morphology was dense and clear. The range analysis showed that the mass fraction of sodium alginate solution, laser pulse energy, spot diameter and thickness of titanium layer are less important influencing the diameter of droplets. At the same time, high-speed camera was used to study the laser-induced sodium alginate solution transfer. it was found that the laser induced liquid target transfer process was accompanied by fluid multiphase dynamic behaviors.
