Motivation for automotive industry

Contrary to conventional subtractive manufacturing technologies, e.g. cutting, lathing, turning, milling and machining, in Additive Manufacturing (AM) a part is created by the consecutive addition of liquids, sheets or powdered materials in ultra-thin layers. The geometrical and structural complexity of additively manufactured parts is limited by almost nothing but the used CAD-model.

        

Using AM technology in automotive enables the production of proto parts before the final tooling is produced, moreover considering low volume projects where the number of components requested are few, it is possible to manufacture parts ready to be mounted on vehicles, and clearly all these actions lead to potential time and cost savings.

Within NOVUM Project, the Fused Deposition Modelling technology is investigated to produce large-scale parts. This combines with the use of bio-based polymer produced from cellulosic waste from the paper industries. Thanks to NOVUM, two relevant goals for the automotive sector are investigated.

The first is the development of large open 3D machine capable of producing big parts, which is useful when a large demo component is needed, and there is no time or budget to manufacture a mold.

The second one is the STELLANTIS commitment to increase the percentage of green material in the cars. In the future vehicles high percentage of the plastics fraction will be from alternative resources such as recycled plastics (post-industrial and post-consumer) and bio-based, and so NOVUM material fits really well the future company needs.
