Abstract

Ink jet nozzles require accurate definition and smooth surface finish to promote laminar flow of ink and prevent turbulence. We have fabricated ink jet nozzles by three different fabrication ttechniques to evaluate the characteristics of each technique and assess the differences between them. Scanning electron micrographs illustrate the differences between the three types of nozzle produced and these have been quantified where possible. The machining times for these fabrication processes are also compared.
