Abstract
Perkembangan teknologi Additive Manufacturing (AM) khususnya dengan metode Fused Deposition Modeling (FDM) telah memungkinkan proses fabrikasi komponen dengan desain geometri yang kompleks serta penggunaan multi-material dalam satu proses pencetakan. Namun, penggunaan multi-material sering menghadapi masalah pada area sambungan karena lemahnya adhesi antar material. Salah satu pendekatan yang dapat meningkatkan kekuatan sambungan adalah dengan menerapkan sistem interlock yang memungkinkan beban tidak hanya ditahan oleh adhesi namun juga ditahan oleh penguncian mekanis. Penelitian ini bertujuan untuk menganalisis pengaruh variasi interlocking structure orientation (30˚, 60˚, dan 90˚), depth (3 mm, 5 mm, dan 7 mm), beam layer counts (1, 2, dan 3) serta beam width (0,4 mm, 0,8 mm, dan 1,2 mm) terhadap kekuatan lentur spesimen multi-material berbahan PLA+ yang difabrikasi menggunakan printer Flashforge Creator Pro 2 dan pengaturan interlock menggunakan software Ultimaker Cura 5.4.0. Pengujian dilakukan menggunakan metode three-point bending dengan standar ASTM D790. Data yang sudah diperoleh dari pengujian, kemudian akan dilakukan analisa menggunakan metode taguchi. Hasil dari pengujian menunjukkan bahwa variasi parameter interlocking structure orientation, depth, beam layer counts, dan beam width memiliki pengaruh signifikan terhadap kekuatan lentur dengan interlocking beam layer counts memiliki pengaruh paling signifikan kemudian diikuti oleh structure orientation, depth, dan beam width yang memiliki pengaruh paling rendah. Penelitian ini memberikan rekomendasi kombinasi parameter interlock optimal untuk meningkatkan performa mekanis komponen multi-material hasil 3d printing, khususnya untuk pengaplikasian yang memerlukan ketahanan lentur yang tinggi.

The development of Additive Manufacturing (AM) technology, especially with the Fused Deposition Modeling (FDM) method, has enabled the fabrication of components with complex geometric designs and the use of multi-materials in a single printing process. However, the use of multi-materials often faces problems in the joint area due to weak adhesion between materials. One approach that can increase the strength of the joint is to apply an interlock system that allows the load not only to be supported by adhesion but also by mechanical locking. This study aims to analyze the effect of variations in interlocking structure orientation (30˚, 60˚, and 90˚), depth (3 mm, 5 mm, and 7 mm), beam layer counts (1, 2, and 3) and beam width (0.4 mm, 0.8 mm, and 1.2 mm) on the flexural strength of multi-material specimens made of PLA+ fabricated using a Flashforge Creator Pro 2 printer and interlock settings using Ultimaker Cura 5.4.0 software. Testing was carried out using the three-point bending method with ASTM D790 standards. The data obtained from the test will then be analyzed using the Taguchi method. The results of the test show that variations in the parameters of interlocking structure orientation, depth, beam layer counts, and beam width have a significant effect on flexural strength with interlocking beam layer counts having the most significant effect, followed by structure orientation, depth, and beam width which have the lowest effect. This study provides recommendations for optimal interlock parameter combinations to improve the mechanical performance of 3D printed multi-material components, especially for applications that require high flexural resistance.
