Abstract

This work describes the process of synthesizing and printing a novel (0-3) piezocomposite material using solution mixing technique and digital light processing technique. This piezoelectric composite material was developed using a photopolymer, grey resin and lead magnesium niobate and lead titanate (PMN-PT) with particles size 5 µm. The 3D-printing of this thick film was achieved using the piezocomposite material with high filler content upto 60% w/w of PMN-PT. Results showed a satisfactory print resolution, a thick film with high flexibility and exceptionally high d33 coefficient of 49 pm/V during single point scan and an average of 67 pm/V during full surface scan measured using the laser vibrometer technique.
