Biodegradable Filament for 3D Printing Process: A Review
Aluri Manoj, Rames C. Panda
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 taken place on the development of biofilaments to replace modern/classic plastic filaments to mitigate the issue of sustainability.Moreover, the use of biofilament will reduce the cost of the filament which limits the use of a petroleum-based filament.This paper analyses the development of various 3D printing biofilaments and their fabrication process reported in the different literature.
