composites reinforced with carbon fiber
Obviously, the mechanical properties of carbon composites were superior to jute composites. However, the mechanical properties of jute composites were better than neat PLA. A 3D printed dog bone tensile specimen is shown in Fig. 9.

(2019), investigated the potential of 3D printing composites reinforced with flax fibers using fused deposition modeling. Flax compos- ites were printed longitudinally and transversally and their properties were investi- gated. The mechanical properties of the printed composites were comparable to continuous glass fiber/polyamide. 2.9 Extrusion Extrusion is a continuous process during this process; thermoplastic raw materials are melted and shaped into continuous length of polymeric products with fixed cross section
