Additive manufacturing or 3D printing is a new way of manufacturing components directly from a CAD model by laying material layer by layer. This method has a tool-less manufacturing process, which produces fully dense components in a little time with high accuracy. The characteristics of additive manufacturing are part complexity, freedom from part consolidation, part design, light-weighting, and design for functional gains of special interest in additive manufacturing for oil and gas, aerospace, marine, and automobile applications. The aim of this work is to manufacture an air intake manifold through additive manufacturing. The intake manifold is manufactured by additive manufacturing process using MakerBot fused deposition modeling (FDM) process. The intake manifold is modeled in Creo parametric software. Steady-state thermal and static structural analysis is carried out on the intake manifold using Ansys Workbench. The additive manufacturing process parameters are optimized for layer thickness, extruder speed, and infill density. The intake manifold is printed with optimized process parameters and fastened to the engine.
