Abstract
3D Printing fused deposition modeling (FDM) merupakan salah satu proses additive manufacturing dengan cara mencetak lapis demi lapis material hingga membentuk suatu produk tiga dimensi. Pada saat proses pencetakan diperlukan temperatur lingkungan yang tepat untuk menghasilkan produk yang baik, oleh karena itu dibutuhkan ruang ber pemanas untuk mengatur temperatur saat proses pencetakan. Maka diperlukan simulasi Computational Fluid Dynamics (CFD) yang bertujuan untuk menganalisis distribusi temperatur yang terjadi di dalam ruang ber pemanas saat proses pencetakan. Penelitian ini menggunakan metode eksperimen dengan software CFD Ansys 2022. Simulasi dijalankan dengan dua kondisi berbeda yaitu menonaktifkan pemanas tambahan dan pemanas tambahan dinyalakan dengan variasi temperatur 70oC, 80oC, 90oC dan 100oC dengan kecepatan aliran udara sebesar 3 m/s. Material produk yang digunakan adalah acrylonitrile butadiene styrene (ABS) dengan ukuran 70 x 30 x 30 mm dengan variasi geometry X, Y dan Z. Berdasarkan dari data hasil simulasi bahwa temperatur di dalam ruang ber pemanas mengalami peningkatan dan pendistribusian temperatur yang merata saat proses pencetakan seiring dengan peningkatan variasi temperatur pada pemanas tambahan hal ini juga menyebabkan pendistribusian heat flux pada produk merata. **** 3D Printing fused deposition modeling (FDM) is one of the additive manufacturing processes by printing layer by layer of material to form a three-dimensional product. At the time of the printing process, the right ambient temperature is needed to produce good products, therefore a heated – chamber is needed to set the temperature during the process printing. Therefore a Computational Fluid Dynamics (CFD) simulation is needed which aims to analyze the temperature distribution that occurs in a heated – chamber during the printing process. This research uses an experiment method with the CFD Ansys 2022 software. The simulation was carried out under two different conditions, the additional heater was turned off and the additional heater was turned on with a Temperatur variation of 70oC, 80oC, 90oC and 100oC with an airflow speed of 3 m/s. Product material used is acrylonitrile butadiene styrene (ABS) with a size of 70 x 30 x 30 mm with variations of geometry X, Y and Z. Based on simulated data, the temperature in the heated – chamber has increased and the Temperatur distribution is evenly distributed during the printing process along with the increase in temperature variations in the Additional heating This also leads to an even distribution of the heat flux in the product.
