Elucidating the Powder Flow Mechanics of Additive Manufacturing
| In an effort to create an innovation-driven manufacturing sector that delivers huge cost-savings without sacrificing part strength, the addition of materials like metals and ceramics to Additive Manufacturing (AM) has emerged as a game changer. AM presents the opportunity to achieve mass customization and the manufacturing of complex internal geometries by simply printing a three-dimensional computer aided design (CAD) file slice by slice. This project focuses on elucidating the powder mechanics involved in creating complex geometries without sacrificing strength and speed. Using in-house modeling and fundamental powder experiments, the PFTL is working with the world's leading AM machines and consumable providers to advance the state-of-the-art.
