Abstract
E-sun standar resin adalah jenis resin berbasis akrilik yang memiliki sifat mekanik yang baik dan banyak digunakan untuk membuat model gigi, peralatan medis, prototipe yang sangat presisi, dan miniatur dengan permukaan yang halus. Resin akrilik adalah polimer sintetis yang terdiri dari monomer berbasis akrilik dan dikenal memiliki sifat transparan. Namun, resin memiliki kelemahan yaitu sifatnya yang getas, mudah retak, tidak ramah lingkungan, dan sulit terdegradasi di lingkungan. Untuk mengatasi permasalahan tersebut, penelitian ini membuat material komposit polimer dengan menambahkan serat alam seperti serat nanas, sabut kelapa, dan eceng gondok. Serat alam dipilih karena bersifat biodegradable dan memiliki sifat mekanik yang baik. Variasi komposisi serat yang digunakan 0, 0.4, 0.8, 1.2, 1.6 wt %. Pembuatan komposit menggunakan metode additive manufacture 3D Print dengan parameter proses pencetakan menggunakan layer thickness 0.050 mm, normal exposure time 25 detik, dan bottom exposure time 25 detik. Metode ini dipilih karena dapat mencetak geometri yang kompleks. Penelitian ini bertujuan untuk menganalisis pengaruh jenis dan komposisi serat terhadap struktur sifat mekanik. Karakterisasi dilakukan untuk mengevaluasi morfologi dengan Scanning Electron Microscopy (SEM), sedangkan identifikasi gugus fungsi kimia dianalisis melalui Fourier Transform Infrared Spectroscopy (FTIR). Struktur kristal material diamati dengan X Ray Diffraction (XRD). Hasil penelitian menunjukkan bahwa penambahan mikrofiber alami berpengaruh terhadap sifat mekanik, viskositas, dan Water absorption. Komposit PF 1,2% menunjukkan kekuatan tarik sebesar 44 MPa, modulus Young sebesar 8 GPa, elongation at break 8.63%, dan densitas 1,17 g/cm³, yang merupakan kombinasi terbaik dari segi kekuatan dan densitas dibandingkan dengan komposit lainnya.

E-sun standard resin is an acrylic-based resin known for its good mechanical properties and is widely used for making dental models, medical equipment, highly precise prototypes, and miniatures with smooth surfaces. Acrylic resin is a synthetic polymer composed of acrylic-based monomers and is recognized for its transparency. However, the resin has drawbacks such as brittleness, susceptibility to cracking, environmental non-friendliness, and difficulty in degradation. To address these issues, this study developed polymer composite materials by adding natural fibers such as pineapple fiber, coconut coir, and water hyacinth. Natural fibers were chosen because they are biodegradable and possess good mechanical properties. The fiber composition variations used were 0, 0.4, 0.8, 1.2, and 1.6 wt%. The composites were fabricated using additive manufacturing 3D printing with process parameters including a layer thickness of 0.050 mm, normal exposure time of 25 seconds, and bottom exposure time of 25 seconds. This method was selected for its ability to print complex geometries. The study aimed to analyze the effect of fiber type and composition on the mechanical properties and structure. Characterization was performed to evaluate morphology using Scanning Electron Microscopy (SEM), chemical functional group identification through Fourier Transform Infrared Spectroscopy (FTIR), and crystal structure observation by X-Ray Diffraction (XRD). The results showed that the addition of natural microfibers influenced mechanical properties, viscosity, and water absorption. The PF 1.2% composite exhibited the best combination of properties, with a tensile strength of 44 MPa, Young’s modulus of 8 GPa, elongation at break of 8.63%, and density of 1.17 g/cm³, outperforming other composites in terms of strength and density.
