A review on optimized FDM 3D printed Wood/PLA bio composite material characteristics

Polylactic Acid (PLA) is a biodegradable polymer having potential to replace the petroleum-based plastics due to its biodegradability and mechanical properties over a great extent. Owing to some of its drawbacks like low thermal resistance, high brittleness due to its hygroscopic nature; it remains obscured for not being completely utilized for machine-based applications or requirements such as load bearing and functional parts, particularly in the mechanical field. In such scenario, fibers are largely used with the thermoplastic filaments as a reinforcement in order to improve the mechanical properties of prepared bio composite material as a feedstock with a view to obtain the 3D printed part produced by FDM (fused deposition modeling).Thus, the PLA bio composites formed with wood have been widely researched and concluded by many authors as the way of making the improvement in the various mechanical properties of the 3D-printed PLA-wood bio composite parts prepared by using the FDM an additive manufacturing process. This review mainly focuses on the mechanical properties of PLA bio composites reinforced with wood fibers considered that the FDM based 3D printing parameters should be optimized using various available multi response optimization techniques. Afterwards, by doing so, the researched bio composite material would be rather utilized for different application areas concerned with mainly mechanical perspectives, wherein environment friendly considerations will be prevailing; thus, before utilization with doing so will be resulting in to reduction in material wastage as well as the optimum time requirementfor performing the experimentation work.
