A maximum flow rate of just over 2,000 ?l/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. The fabrication of actuator components using stereolithography apparatus (SLA) is a potentially major step towards the realisation of low-cost, disposable, rapid manufactured and fully integrated micro total analysis systems (?TAS).

Abstract

In this paper we present the world’s first micropump entirely fabricated using a 3D direct manufacture process based on microstereolithography. The device employs a single pneumatically actuated membrane, with flow rectification provided by a nozzle/diffuser arrangement. A maximum flow rate of just over 2,000 ?l/min was achieved with a pneumatic pressure of 2 PSIG and a stroke rate of 96 Hz. The fabrication of actuator components using stereolithography apparatus (SLA) is a potentially major step towards the realisation of low-cost, disposable, rapid manufactured and fully integrated micro total analysis systems (?TAS).
