Green polymers filaments for 3D-printing
Résumé
3D printing or additive manufacturing is a technology that has drastically developed in recent years for numerous industrial applications. Among the 3D printing methods the fused deposition modeling (requires filaments to generate a three dimensional objects. Currently, the polymers used in this technology are synthetic ones, derived from non renewable resources such as petroleum. Green polymers (including natural polymers) are a sustainable alternative of them as they are biodegradable/recyclable, non toxic and abundant. However the implementation in 3D printing of the major part of them remains a challenge. This chapter is focused on the most famous and promising biodegradable polymers from biomass, produced by microorganisms or derived from biotechnology for applications using fused deposition modeling. Their thermal, rheological and mechanical properties are also discussed in details.
