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 a complex shape. This complex geometry is get by the built up layer-by-layer process. The AM technologies offer different solutions based on resin or powder materials which use the synthesis materials with environmental impact. The primary aim of this study was to create objects in reconstituted wood through a rapid manufacturing with low environmental impact. Wood is transferable through various derivatives allowing the introduction of sustainable material into the product lifecycle. The project is based on an AM device adapted on a Computer Numerical Control (CNC) machine  in order to produce a reconstituted wood product by filament deposition. A first part assessed the deposit of wood pulp with a 3D printing head device, while the second part focuses on the microscopic structure of the material. The research studies especially the filament behavior and its originality is based on determination of mechanical properties of renewable wood product based on additive manufacturing in order to define the better use area. The fiber structure from biomass is presented with its strengthening advantages. The filament morphology with a homogenous cross section influences the mechanical properties and requests a mechanical characterization. This article tends to better understand the influence of composite material proposed into the deposition modeling additive process.
