Abstract

Produk hasil cetak Fused Deposition Modeling (FDM) umumnya memiliki sifat mekanik anisotropik akibat lemahnya ikatan antarlayer, sehingga berpotensi menurunkan kekuatan tarik dan menyebabkan delaminasi. Penelitian ini bertujuan untuk menganalisis pengaruh variasi beam layer count dan structure orientation interlock terhadap kekuatan tarik spesimen material PLA+, serta menentukan kombinasi parameter yang optimal. Metode yang digunakan adalah eksperimen dengan rancangan percobaan Taguchi melalui orthogonal array, di mana spesimen dicetak menggunakan proses FDM dan diuji tarik berdasarkan standar ASTM D638 Tipe I. Data dianalisis menggunakan S/N ratio, ANOVA, dan uji post hoc Tukey. Hasil penelitian menunjukkan bahwa seluruh parameter yang diteliti berpengaruh signifikan terhadap kekuatan tarik, dengan structure orientation sebagai faktor paling dominan, diikuti oleh beam width, depth, dan beam layer count. Kombinasi parameter optimal yang dihasilkan adalah structure orientation 60°, beam layer count 3, beam width 0,4 mm, dan depth 6 mm. Analisis fraktografi pada spesimen optimal menunjukkan adanya deformasi plastis yang mengindikasikan mekanisme kegagalan ulet. Kesimpulannya, penerapan struktur interlock dengan parameter yang tepat terbukti mampu meningkatkan kekuatan tarik material PLA+ pada proses FDM secara signifikan.

The development of Fused Deposition Modeling technology enables the fabrication of components with complex geometries; however, printed parts commonly exhibit anisotropic mechanical properties due to weak interlayer bonding. One approach to improve tensile strength is the application of interlock structures with variations in internal design. This study aims to analyze the effect of beam count and structure orientation interlock on the tensile strength of PLA+ specimens and to determine the optimal interlock parameter combination. The research method employs an experimental approach using the Taguchi method through an orthogonal array design. Specimens are fabricated using the FDM process and tested under tensile loading in accordance with the ASTM D638 Type I standard. The experimental data are analyzed using the Signal to Noise ratio and analysis of variance to evaluate the influence and contribution of each parameter. The expected results of this study are the identification of optimal interlock parameters that enhance the tensile strength of PLA+ material and provide design recommendations for interlock structures in FDM-based 3D printing.
