Characterization of wood filament in additive deposition to study the mechanical behavior of reconstituted wood products

Abstract

The use of materials derived from biomass is unavoidable to decrease environmental impact of products. The main advantage of the Additive Manufacturing (AM) concept is the ability to create complex geometries one layer at a time. The primary aim of this study was to create objects using reconstituted wood through manufacturing with low environmental impact. Wood can be converted into various derivatives allowing the introduction of sustainable material into the product lifecycle. This work uses an AM device adapted to a Computer Numerical Control (CNC) machine [1] to produce a reconstituted wood product by filament deposition. The first part assessed the deposit of wood pulp with a 3D printing head device, while the second part focuses on the characterization of microscopic structure of the material. Fiber morphology and mechanical properties of composite materials incorporating the filaments are characterized.
