DROPLET SELECTION MECHANISM

摘要

A method and droplet selection device are provided for a continuous printer for selectively deflecting a droplet from a predetermined printer trajectory. In particular, a droplet selection device is provided for a continuous printer, comprising a droplet ejection system (10) arranged to generate a continuous stream of droplets (6) from a first fluid jetted out of an outlet channel (5), and a jet system (70) arranged to generate a second jet (61) for colliding the jet into the stream of droplets. The jet system comprises a deflector (71), to selectively deflect the second jet into the continuous stream of droplets, so as to selectively deflect the droplets from a predefined printing trajectory.
