Abstract
Perkembangan teknologi cetak 3D telah memberikan kemudahan dalam mencetak objek dengan bentuk yang kompleks. Namun, harga 3D print komersial yang cukup tinggi yaitu sekitar Rp 4.000.000 masih menjadi kendala khususnya di lingkungan Pendidikan. Oleh karena itu, penelitian ini bertujuan untuk merancang dan membuat mesin 3D printer berbiaya rendah (low-cost) yaitu dibawah Rp 2.500.000 dengan mempertimbangkan pemilihan komponen, material, serta performa mekaniknya. Penelitian ini melalui tahapan desain mekanik, pemilihan material, perakitan, hingga pengujian akurasi hasil cetak. Material utama yang digunakan adalah aluminium untuk rangka karena ringan dan kuat, serta PLA untuk komponen pendukung. Sistem penggerak menggunakan kombinasi belt dan pulley untuk sumbu X dan Y, serta lead screw untuk sumbu Z. Analisa tegangan dilakukan menggunakan simulasi finite element analysis (FEA) dan nilai tegangan maksimunya adalah 0,536 MPa, yang menunjukkan bahwa seluruh komponen mekanik berada dalam batas aman tegangan ijinnnya adalah 36,67 MPa. Pengujian hasil cetak menunjukkan bahwa printer dapat mencetak objek dengan bentuk dan dimensi yang mendekati dimensi desain, dengan toleransi kurang lebih 2 mm. Dengan demikian, 3D printer ini layak digunakan untuk kebutuhan Pendidikan dan penelitian dengan biaya yang lebih terjangkau.

The development of 3D printing technology has made it easier to produce objects with complex shapes. However, the relatively high cost of commercial 3D printers around IDR 4,000,000 remains a major obstacle, particularly in educational environments. Therefore, this research aims to design and build a low-cost 3D printer priced below IDR 2,500,000 by considering component selection, material choice, and mechanical performance. The research process includes mechanical design, material selection, assembly, and print accuracy testing. The main materials used are aluminum for the frame due to its light weight and strength, and PLA for supporting components. The motion system combines belt and pulley mechanisms for the X and Y axes, and a lead screw for the Z axis. Stress analysis was conducted using finite element analysis (FEA), and the maximum stress obtained was 0.536 MPa, which is well below the allowable stress of 36.67 MPa, indicating that all mechanical components are operating within safe limits. The print accuracy tests show that the printer can produce objects with dimensions close to the original design, with a tolerance of approximately 2 mm. Therefore, this low-cost 3D printer is suitable for educational and research purposes at a more affordable cost.
