The RPSA technology employs a piezoceramic transducer to propel fluid from a chamber. The piezoceramic expands in response to an electrical signal, which pushes against a flexible diaphragm. As the diaphragm is displaced, a pressure pulse is created within the chamber and a droplet is ejected through the orifice in a push mode.

The all-metal laminate designs are assembled using a proprietary bonding process and refined construction techniques that have been developed over the past 15 years of OEM manufacturing. RPSA has provided more industrial grade piezo DOD print heads than any other current supplier. RPSA piezo print heads are durable and provide the flexibility to address the requirements of many industrial applications.
