Abstract

Music box merupakan alat musik mekanik yang menghasilkan melodi melalui petikan bilah logam (comb) oleh tonjolan pada barrel yang berputar. Umumnya, komponen utama seperti rangka atau base dari music box dibuat menggunakan bahan logam karena sifat akustiknya yang baik dalam menghantarkan resonansi suara. Namun, penggunaan logam memiliki kekurangan seperti proses manufaktur yang rumit, dan keterbatasan kustomisasi bentuk. Penelitian ini menggunakan mesin 3D printing dengan metode Fused Deposition Modeling (FDM). Material yang digunakan adalah PLA (Polylactic Acid) karena mudah dicetak, ringan, dan terjangkau, meskipun memiliki karakteristik akustik yang berbeda dibandingkan logam. Tujuan dari penelitian ini adalah untuk mencari parameter proses pencetakan 3D printing yang optimal terhadap kekuatan suara yang dihasilkan oleh base music box. Parameter yang divariasikan meliputi kecepatan cetak (printing speed) dan ketebalan lapisan (layer height), serta penambahan spacer logam. Pengaturan parameter dilakukan melalui software Creality Print, dan hasil cetakan diuji dengan pengukuran intensitas suara menggunakan software Audacity. Data dianalisis menggunakan uji ANOVA satu arah (One Way ANOVA) untuk mengetahui pengaruh parameter terhadap respon intensitas suara. Hasil penelitian menunjukkan bahwa kombinasi parameter terbaik untuk base tanpa spacer terdapat pada printing speed 40 mm/s dan layer height 0,2 mm, menghasilkan intensitas suara tertinggi sebesar –55,00 dB. Sementara itu, pada base dengan spacer, kombinasi parameter yang sama menghasilkan intensitas tertinggi sebesar –52,67 dB. Penambahan spacer logam terbukti meningkatkan power suara dan memperbaiki distribusi resonansi. Sebagai pembanding, intensitas suara music box pabrikan berbahan logam mencapai –51,00 dB, menunjukkan bahwa hasil dari base PLA dengan parameter optimal mendekati performa akustik dari produk pabrikan.

A music box is a mechanical musical instrument that produces melodies through the plucking of metal tines (comb) by rotating barrel pins. Generally, the main structural component such as the base of a music box is made from metal due to its excellent acoustic properties in transmitting sound resonance. However, metal-based manufacturing has several drawbacks, including complex fabrication processes and limited shape customization. This study utilizes a 3D printing machine with the Fused Deposition Modeling (FDM) method. The material used is PLA (Polylactic Acid) due to its ease of printing, light weight, and affordability, although it has different acoustic characteristics compared to metal. The objective of this research is to determine the optimal 3D printing process parameters that affect the sound strength generated by the music box base. The varied parameters include printing speed and layer height, along with the addition of a metal spacer. Parameter settings were configured using Creality Print software, and the printed bases were tested by measuring sound intensity using Audacity software. The data were analyzed using One-Way ANOVA to identify the effect of each parameter on the sound intensity response. The results show that the best combination for the base without a spacer was at 40 mm/s printing speed and 0.2 mm layer height, producing the highest sound intensity of –55.00 dB. Meanwhile, with the addition of a spacer, the same parameter combination yielded an improved intensity of –52.67 dB. The addition of a metal spacer significantly enhanced sound power and improved vibration distribution. As a comparison, the sound intensity of a factory-made metal music box reached –51.00 dB, indicating that the optimally printed PLA base can approach the acoustic performance of commercially manufactured music boxes.
