Drop-on-demand (DOD) printing technology has been applied across various fields. Flexibility and efficient use of printing materials attracts applications where object accretion layer-by-layer is essential. This paper presents the application of DOD in manufacturing planar ion-selective electrodes (ISE) from all liquid materials. The custom development of key hardware lowers the cost of DOD machine besides enables direct control to each device. The printing materials are specifically formulated to meet functional demands of ISEs while not compromise dispenser capability.

Keywords: Drop-on-demand, Layer-by-layer, Ion-selective electrode, Photopolymer and Dispenser.
