In the past decade, some studies have been reported on the 3D printing of energy storage devices (ESD) by using recycled thermoplastics (such as acrylonitrile–butadiene–styrene (ABS), polyamide, etc.) through fused deposition modeling (FDM). But hitherto little has been reported on the development of recyclable and flame retardant ESD (by using recycled thermoplastics and thermosetting composite). In this work, efforts were made to 3D print ESD with flame retardant capabilities on FDM by using an ABS-melamine formaldehyde (C4H8N6O) (ABSM) based composite matrix. The components of ESD were prepared in four sections/segments. Three sections were: 3D printed ABSM-based composites reinforced with graphite (Gr), MnO2, and electrolyte (NH4Cl + ZnCl2), and the fourth section was of Zn cast plate. The functional prototype as ESD has been prepared by assembling these four sections. Final observations are supported based upon thermal, mechanical, morphological, flame retardant, V-I, and V-R characterization.
