The Dropwatcher is a tool for visualising drops ejected during printing.
It works by capturing images of drops in flight using high-powered optics. These images are then analysed to measure :
- The distance between the drops in the vertical and horizontal directions
- The straightness of the jets
- Drop volume
- Ejection repeatability
By adjusting ejection parameters such as temperature, waveform or frequency, the researcher will be able to optimise the ejection according to his or her expectations.
Dropwatcher is a unique tool because it allows ejection to be viewed from several angles thanks to two devices:
- A bracket on which the camera is fixed: measurement of the angles of contact of the drop with the substrate, goniometer function.
- A lever arm to which the head is attached: the nozzle plate can be viewed from horizontal (0°) to vertical (90°).
