On-Site Speaker (Planned) William Carter
Abstract Scope Structural direct-write additive-manufacturing is a layered filament based metal manufacturing technology wherein liquid material is deposited from a print head directly onto a print bed, where it solidifies, retaining an intended shape and bonding with a layer of the same material upon which it is deposited. This process has been enabled for metals by the unique rheological properties of rare-earth modified aluminum alloys to create a scalable direct metal write system. Tailoring the rheology of the alloy has allowed for a system that is capable of direct write additive manufacturing of metal parts at room temperature in air. Removing the requirement for large ovens and tailored atmospheres significantly increases the accessibility of metal additive manufacturing. The system can also be used to create large and small scale parts with faster build rates than traditional metal additive manufacturing methods.
