Analysis of Droplet Train/Moving Substrate Interactions in Ink-Jetting Processes

摘要

Ink-jetting technology has been applied to several processes in solid free-formrnfabrication (SFF) wherein droplets impinge onto a substrate to deposit the build material.rnDroplet impact behaviour on a surface has been the interest of many researchers; however,rnfew studies have been undertaken to investigate the interaction of droplets with the movingrnsubstrate. This paper reports the impact behaviour of the droplets jetted at differentrnfrequencies onto a substrate moving over a range of velocities. The phenomena associatedrnwith the interaction were classified into three main regimes.
