Biodegradable Filament for Three-Dimensional Printing Process: A Review

Abstract

Three-dimensional (3D) printing is a transformative fabrication process that allows 3D objects to be formed by the layer deposition of the materials. At present, a fused deposition modeling 3D printer uses non-biodegradable materials to fabricate the filament for 3D printing. The innovative manufacturing strategies and possibilities accelerated the use of different kinds of biological materials in 3D printing or additive manufacturing. A lot of research has been taken place on the development of biofilaments to replace the modern/classic plastic filament to mitigate the issue of sustainability. Moreover, the use of biofilament will reduce the cost of the filament which limits the use of petroleum-based filament. This paper analyses the development of various 3D printing biofilaments and their fabrication process reported in the different literature.
