Abstract

Manufaktur aditif teknik Fused Deposition Modeling (FDM) menjadi tekonologi populer dalam industri manufaktur saat ini. Salah satu patokan atau benchmark yang umum digunakan untuk menilai kualitas hasil cetak 3D print FDM adalah dilihat dari surface roughness yang dipengaruhi oleh berbagai hal seperti getaran dan parameter pencetakan. Dari latar belakang tersebut, penelitian ini bertujuan untuk mengidentifikasi parameter yang mempengaruhi kekasaran permukaan dan kekerasan hasil cetak 3D Print material PLA+ menggunakan metode ANOVA. Dengan menurunkan level parameter layer height dan printing speed serta menggunakan level parameter extruder temperature penlitian terdahulu, hasil ANOVA menunjukkan bahwa semakin rendah level layer height, nilai surface roughness juga semakin rendah. Hasil ANOVA juga menunjukkan bahwa semakin rendah level layer height, nilai hardness juga semakin rendah. Sedangkan semakin rendah level print speed, nilai hardness mengalami peningkatan.
Untuk mendapatkan hasil cetak yang baik, diperlukan sistem monitoring getaran dan model prediksi dengan akurasi yang tinggi. Pada penelitian ini, juga dilakukan penambahan data pada model machine learning untuk prediksi surface roughness dari penelitian terdahulu untuk mengetahui pengaruhnya terhadap nilai akurasi model. Setelah dilakukan penambahan data dari penelitian ini, akurasi model machine learning penelitian terdahulu untuk set pelatihan meningkat dari 82% menjadi 85% dan untuk set pengujian meningkat dari 84% menjadi 92%.

Fused Deposition Modeling (FDM) additive manufacturing is becoming a popular technology in the manufacturing industry today. One of the benchmarks commonly used to assess the quality of FDM 3D prints is surface roughness which is influenced by various things such as vibration and printing parameters. From this background, this research aims to identify parameters that affect the surface roughness and hardness of 3D printed PLA+ material using the ANOVA method. By lowering the level of layer height and printing speed parameters and using the extruder temperature parameter level of previous research, the ANOVA results show that the lower the layer height level, the lower the surface roughness value. The ANOVA results also show that the lower the layer height level, the lower the hardness value. While the lower the print speed level, the hardness value increases.
To get good printing results, a vibration monitoring system and a prediction model with high accuracy are needed. In this study, data was also added to the machine learning model for predicting surface roughness from previous studies to determine its effect on the accuracy of the model. After the addition of data from this study, the accuracy of the previous research machine learning model for the training set increased from 82% to 85% and for the testing set increased from 84% to 92%.
