Depositing dual thermoplastics in a core–shell structure, an alternative to blending, can be utilized to build components with localized, customized, and specialized qualities. Therefore, there is always a scope to research extrusion-based (MEX) 3D printing (3DP) of dual thermoplastic materials in a core–shell pattern for various engineering applications. In this investigation, trials were undertaken to explore the tensile resilience of specimens crafted from two thermoplastic substances, namely acrylonitrile–butadiene–styrene (ABS) denoted as A, and polylactic acid (PLA) referred to as P, employing a cost-effective material extrusion (MEX) 3DP technique. The specimens in four different composition ratios (80/20), (60/40), (40/60), and (20/80) by weight percentage in (ABS-PLA-ABS) core–shell form have been fabricated and tested for tensile strength as ASTM-D638 standard. According to the study’s findings, the weight % of the material considerably impacts the tensile strength of 3DP objects. For example, in tensile testing, the specimen with a combination of one layer of ABS-8 layers of PLA-one layer (APPPPPPPPA) of ABS has a maximum strength of 43.50 MPa, which surpasses the ABS by 35.81%. Moreover, the thermographs of ABS and PLA explained why the extrusion of ABS on the PLA platform gives stronger bonding than PLA on ABS.

摘要

Depositing dual thermoplastics in a core–shell structure, an alternative to blending, can be utilized to build components with localized, customized, and specialized qualities. Therefore, there is always a scope to research extrusion-based (MEX) 3D printing (3DP) of dual thermoplastic materials in a core–shell pattern for various engineering applications. In this investigation, trials were undertaken to explore the tensile resilience of specimens crafted from two thermoplastic substances, namely acrylonitrile–butadiene–styrene (ABS) denoted as A, and polylactic acid (PLA) referred to as P, employing a cost-effective material extrusion (MEX) 3DP technique. The specimens in four different composition ratios (80/20), (60/40), (40/60), and (20/80) by weight percentage in (ABS-PLA-ABS) core–shell form have been fabricated and tested for tensile strength as ASTM-D638 standard. According to the study’s findings, the weight % of the material considerably impacts the tensile strength of 3DP objects. For example, in tensile testing, the specimen with a combination of one layer of ABS-8 layers of PLA-one layer (APPPPPPPPA) of ABS has a maximum strength of 43.50 MPa, which surpasses the ABS by 35.81%. Moreover, the thermographs of ABS and PLA explained why the extrusion of ABS on the PLA platform gives stronger bonding than PLA on ABS.
