APPARATUS AND METHOD FOR DIRECT LASER PRINTING

摘要

The invention relates to the direct printing of liquids that are transparent to, or weakly absorbent of, laser radiation on a receiver substrate, using a laser pulse strongly focused at a shallow point within the liquid contained in a container. The invention avoids the drawbacks of preparing a liquid film such as that which has been used in the prior art and allows repeated incidence of the laser pulse in the same position in the liquid without a reduction in reproducibility. The invention likewise makes it possible to print well-defined microdrops with a high degree of reproducibility.
