Mesh-like parts are employed in order to reduce weight of mechanical structures. This study focused on cylindrical shaped mesh-like spacers. First, the mesh shape was parametrically defined and mechanical strength and strain under specific combination of axial and shear loads were determined by numerical simulation. Manufacture of the best design was then investigated focusing on investment casting under both gravity and vacuum modes with a simple, yet uncommon, top feeding system. The best combination of casting mode and parameter values was determined by numerical simulation on commercially available dedicated software, considering solidification time and lack of defects as primary quality indices accompanied by an investigation of residual stress and deformation fields. To implement simulation-based decisions the part was investment-cast employing 3D printed dies for constructing the wax models.
