Abstract
Three-dimensional (3D) printing is an outstanding technology and performs a significant role in the fabrication of sensors as compared to conventional methods of fabrication, such as subtractive manufacturing. In this review paper, fabrication of general-purpose sensors using traditional manufacturing and 3D printing has been discussed. All possible sensors, including mechanical sensors, electronic sensors, biosensors, and chemical sensors can be fabricated using 3D printing technologies in a cost-effective, rapid and eco-friendly manner. Among various 3D printing technologies, fused deposition modelling and inkjet printing method have been prominently utilized. With the advent of new materials and flexibility in the printing process, these technologies show immense advantages and potential in the development of sensors. Future sensing applications include advanced biosensors for tissue engineering, high-performance sensing capabilities, such as high power sensors and improvement in multifunctional sensors.
