| dc.description.abstract | Teknologi pencetakan 3D telah maju pesat sebagai metode manufaktur aditif yang mampu menghasilkan objek dengan bentuk yang kompleks. Penelitian ini bertujuan untuk menganalisis kekuatan tekan hasil pencetakan 3D printer berbahan logam melalui teknologi pengelasan MIG (Metal Inert Gas) dengan menggunakan kawat las MIG tipe E71T-GS sebagai material dasar. Spesimen dicetak dengan variasi arus listrik 50 A, 60 A, dan 70 A, kemudian diuji tekan menggunakan mesin Universal Testing Machine (UTM) sesuai standar ASTM E9-19. Hasil pengujian menunjukkan bahwa peningkatan arus pencetakan meningkatkan kekuatan tekan spesimen. Tegangan tekan tertinggi rata–rata sebesar 844,31 MPa diperoleh pada arus 70 A, Arus 60 A menghasilkan tegangan rata-rata sebesar 821,41 Mpa dan Arus 50A menghasilkan tegangan rata- rata 788,09 MPa. Penelitian ini membuktikan bahwa teknik pencetakan logam 3D dengan integrasi proses pengelasan MIG dapat menghasilkan komponen yang memiliki karakteristik mekanik yang baik dan dapat dikembangkan untuk aplikasi industri otomotif, medis, dan manufaktur. 3D printing technology has advanced rapidly as an additive manufacturing method capable of producing objects with complex shapes. This study aims to analyze the compressive strength of 3D printing results from metal printers through MIG (Metal Inert Gas) welding technology using MIG welding wire type E71T-GS as the base material. Specimens were printed with varying electric currents of 50 A, 60 A, and 70 A, then tested in compression using a Universal Testing Machine (UTM) according to ASTM E9-19 standards. The test results showed that increasing the printing current increased the compressive strength of the specimens. The highest average compressive stress of 844.31 MPa was obtained at a current of 70 A, a current of 60 A produced an average stress of 821.41 MPa and a current of 50A produced an average stress of 788.09 MPa. This study proves that 3D metal printing techniques with the integration of the MIG welding process can produce components that have good mechanical characteristics and can be developed for applications in the automotive, medical, and manufacturing industries. | en_US |
