Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) are two of the most commonly used techniques in 3D printing as additive manufacturing to produced “objects” for several sectors such as furniture in construction field and in packaging sector. 3D printing, can be described as a process of joining different layers of materials to create 3D objects through what is called a “Surface Tessellation Language file” (.stl) obtained from a CAD-assisted design. The usable process temperatures reach values up to 300°C, the thickness of filaments can reach value until 1.75 mm. These parameters permit the processing several typology of materials: PLA, composite PLA, TPU, ABS, etc...
