3D printing as the state-of-the-art emerging technology offers a platform for the new industrial horizons. The manufacturing process for creating 3D physical objects done via successive layer-by-layer deposition of materials such as metal, plastic, ceramics, or even living cells. The 3D printing concept was first proposed in the 1980s using stereolithography to make polymer objects. 3D technology could transform manufacturing, global product consumption and supply chains. The cover photo of July 2019 issue describes the structure of a 3D printed objects and to celebrate the 39th anniversary of its innovation.

The involvement and development of intelligent polymers in enzymes as a catalyst have been interesting to develop processes that are environmentally benign, energy efficient, and selective towards their specific molecular applications. Polypyrrole based enzyme nanocomposites represents a continuous considerable redox organic polymer that have been increased in electromechanical devices in advance for surface functionalization. This review addresses the fundamental concepts of polypyrole and its composites role for enzyme immobilizing functioning and its bio functional bioelectrocatalytic system operating principle in biosensor and biofuel cells as well as its involvement in electron transfer mechanism as a bio electrode to create an advanced bioelectronics device from power generating system to extreme analyte detecting system. © VBRI Press.
