Proposed methodology for sustainability assessment using MCDA-AHP: Future study and recommendation in 3D printing technology

Abstract

Sustainability is widely recognized as the consequence of a balance between the three main pillar aspects; environmental, economic, and social of sustainable development. The research of sustainability assessment has shown less attention in the context of 3D printing technology among researchers. Besides, when technology is integrated, a sustainability assessment is required, and it will improve coordination in avoiding undesirable consequences. This research proposed the methodology to establish extensive plans that take into consideration all relevant aspects for 3D printing technology by using the MCDA of the AHP method. Also, focused on the system boundary from cradle-to-gate; hydroxyapatite (HA) slurry and 3D gel-printing technology. The sustainability survey of MCDA methodology had been highlighted in this research. 1.6% of calculated CR value is acceptable and reasonably consistent for the amount of inconsistency CR which is less than 10%. The consideration of the framework for 3D printing technology which is the sustainability assessment and improvement is proposed as a guide for future works. In a nutshell; deep understanding importance of sustainability assessment will assist in the development of 3D printing more effectively and efficiently.
