Abstract

Sustainable resources are one of the important aspects in maintaining the stability of nature. Nowadays, one of the major concerns is the development of recycled materials as additives or even substitutes for raw materials. This research aims to examine the possibility of using recycled materials in additive manufacturing (AM) in order to reduce the environmental impact. In this regard, oyster shells are considered as one of the wastes that can be utilized as a sustainable resource in the AM process. The current study involves the use of oyster shells and recycled clay as the feeding material for the 3D printer. The results revealed that the quality of fabricated products from recycled oyster shell raw materials was comparable to products made from conventional raw materials. The average flexural strength and compression strength of products fabricated through recycled material are 19.06 MPa and 429.57 kPa, respectively. In addition, this study also examines the impact of using recycled oyster shells on the green supply chain and its contribution to the circular economy. The utilization of recycled raw materials in the AM processes also positively impacts cost efficiency
