Abstract
Teknologi 3D Print Multimaterial Additive Manufacturing (MM-AM) merupakan metode inovatif dalam mencetak objek dengan menggunakan berbagai jenis material secara bersamaan. Meskipun demikian, terdapat permasalahan potensial terkait ikatan yang lemah antar-material yang dapat mempengaruhi kekuatan dan kualitas produk hasil cetakan. Penelitian ini bertujuan untuk mengatasi persoalan tersebut dengan memanfaatkan fitur interlock sebagai solusi. Penelitian ini berupaya untuk mengetahui pengaruh penggunaan interlock structure geometry jigsaw dan T-shape terhadap kekuatan tarik material khususnya pada material filament polylactic acid (PLA) yang diperkuat menggunakan fitur parameter interlock di software Ultimaker Cura 5.4 interlock dengan parameter interlock orientation 45° dan 90°, serta interlock depth 1 mm dan 2 mm. Kemudian dilakukan pengujian tarik yang sesuai standard ASTM D638 untuk mengetahui kekuatan tarik material hasil pencetakan 3D Print. Data yang diperoleh kemudian dilakukan analisa menggunakan metode Analysis Of Variance (ANOVA). Hasil dari penelitian ini menunjukkan bahwa kekuatan tarik tertinggi terdapat pada spesimen yang difabrikasi menggunakan fitur geometry interlock dengan fitur interlock di software Ultimaker Cura. Hasil analisa menunjukkan bahwa penggunaan parameter yang paling optimal dengan menggunakan variasi interlocking structure geometry jigsaw dengan nilai 25,13 Mpa dan variasi interlocking depth 1 mm dengan nilai 23,09 MPa serta variasi interlocking structure orientation 45˚ dengan nilai 22,96 MPa. Hal tersebut membuktikan bahwa faktor-faktor tersebut berpengaruh dalam meningkatkan kekuatan tarik produk 3D print.

Multimaterial Additive Manufacturing (MM-AM) 3D printing technology is an innovative method of printing objects using different types of materials together. However, there are potential problems related to weak bonds between materials that can affect the strength and quality of the printed product. This research aims to address these issues by utilizing the interlock feature as a solution. This research seeks to determine the effect of using jigsaw and T-shape geometry interlock structures on the tensile strength of materials, especially polylactic acid (PLA) filament materials reinforced using the interlock parameter feature in Ultimaker Cura 5.4 interlock software with interlock orientation parameters of 45° and 90°, and interlock depths of 1 mm and 2 mm. Then tensile testing was carried out in accordance with ASTM D638 standards to determine the tensile strength of 3D printed materials. The data obtained was then analyzed using the Analysis of Variance (ANOVA) method. The results of this study show that the highest tensile strength is found in specimens fabricated using geometry interlock features with interlock features in Ultimaker Cura software. The analysis shows that the most optimal parameter usage is using the interlocking structure geometry jigsaw variation with a value of 25.13 MPa and the interlocking depth variation of 1 mm with a value of 23,09 MPa and the interlocking structure orientation variation of 45˚ with a value of 22,96 MPa. This proves that these factors are influential in increasing the tensile strength of 3D printed products.
