Abstract
This presentation summarises recent work at The University of Manchester on additive manufacturing of multiple material components and functionally graded components, based on modified laser powder bed fusion. Selective powder delivery via multiple ultrasonic nozzles is combined with selective powder removal and powder bed fusion. Such a system has been used to manufacture metal-metal, metal-ceramic, metal-glass, metal-polymer, ceramic-polymer components. The material characteristics at the multiple material interfaces are analysed. Modelling and simulation are used to understand the process behaviour. Examples of potential applications are given.
