Session: 31, Room:
Additive manufacturing, also known as three-dimensional (3D) printing, is a state of the art technology that has been gaining momentum in several applications including aerospace, automotive industry and the medical field. Recently, 3D printing has also gained attention as a promising fabrication pathway for key components of membrane-based systems for desalination and water treatment as well. The unique benefit of 3D printing over conventional manufacturing processes lies in its ability to fabricate structures with complex morphologies that can be optimized for fluid flow, heat transfer, etc., based on the targeted application. One such class of complex geometries are triply periodic minimal surfaces (TPMS), which can be described mathematically such that they have no self-intersecting or enfolded surfaces. “Triply periodic” means that the structure can be patterned in the 3D space and “minimal surface” means that it locally minimizes surface area for a given boundary such that the mean curvature at each point on the surface is zero. These shapes have been shown to have been investigated for applications ranging from aerospace to biomedical tissue engineering. They have various properties with regards to enhanced, smooth fluid flow that make them ideal candidates for a number of applications in water research. Primary among these applications is the design of feed spacers, which was investigated by our research group over the last 3 years.
