Sustainable manufacturing strategies: a literature review on additive manufacturing approach
This article aims to provide a literature review regarding sustainability in additive manufacturing. The purpose is to understand the literature main structure concerning sustainability in additive manufacturing in order to identify the field’s key challenges. The article employees a systematic literature review on the main topics of sustainability in additive manufacturing. Data were collected in one of the main data bases considering the journal impact factor reports. Articles on the subject were searched and retrieved, and a content analysis was carried out. An evaluation of the challenges in this field was also performed. Additive manufacturing potentially impacts the productive process sustainability in various manners. Several are the research challenges in this field of studies. The literature on sustainability in manufacture presents numerous indicators. However, the literature on sustainability in additive manufacture lacks quantitative research to evaluate these proposed indicators. It is necessary to perform quantitative research in order to evaluate the adequacy of additive manufacturing. This literature review shows multiple additive manufacture impacts on sustainability. Promising studies point out some of these impacts, although there are still some sustainability research gaps on additive manufacturing. This article presents some of these gaps thus allowing researchers to identify research opportunities.
