3D Printing as a Disruptive Technology for the Circular Economy of Plastic Components of End-of-Life Vehicles: A Systematic Review

The automotive industry is frequently associated with high polluting manufacturing systems, which raise concern owing to the current environmental frame. For this reason, new alternative technologies lower impact have been proposed and tested, such as additive (AM). Since AM produce almost no waste, they can represent a huge opportunity for become greener. In sense, object of present review explore challenges strategies 3D printing, recycling, circular economy in industry. Therefore, achieve aim study, systematic methodology was used five stages: (1) defining targets; (2) extraction papers from Scopus; (3) text mining corpora analysis relevant documents platform; (4) identification dominant categories research topics; (5) discussion control obtained results provision recommendations future studies. 14 articles revealed that printing technology represents an empower small-scale producers polymers, recycle ELV materials, decentralize supply chains plastic articles. possibility include parts produced by has pointed out innovative option car manufacturers. Unfortunately, till day, poor information found regard. Findings highlighted need turn polymeric components into more eco-friendly safer improve chain perform sustainability assessments, reformulate waste policies ELVs.
