Additive Manufacturing technology can now speed up and improve the accuracy of the manufacturing process. Manufacturing products with 3D Metal printing gets simpler, quicker, and more precise. Recent studies showed that 3D metal printing with the type laser powder bed fusion (LPBF) could produce primary air fans (PAF) for industrial applications with a quality that can be compared with the existing model. LPBF manufacturing process showed errorless and had advantages compared with the traditional process, allowing the development of precise 3D shapes and sizes. The penetration tests with visual inspection revealed that the 3D printed product has no surface defects. The surface roughness test showed that the specimen has a slightly more refined surface than the original product. The chemical test showed that 3D metal printing materials resemble original model materials, with Aluminium 89.6% wt. and Silicon 9.57% wt., while other elements are less than 1%. The average hardness of 3D material metal printing is 91.6 HV, while the original model material is 106.03 HV. Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX) tests indicate that the oxide that forms is Al2O3. |
