Abstract
AbstractThis work is aimed to develop, by means of conventional extrusion technologies for polymer processing, novel poly(lactide)/microcrystalline cellulose (PLA/MCC) filaments for 3D printing. The biocomposite filaments, produced at four different MCC loadings (6, 9, 12, and 18 wt%) by melt blending in extruder, are characterized in terms of rheological, thermal, and mechanical response. The analyses demonstrate that the MCC addition up to 12 wt% does not significantly modify the viscoelastic flow behavior of the matrix, and does not change its phase transition temperatures, but increases the storage modulus at 35°C by over 45%.
