Purpose and goal
The project aims at developing a new process for feeding of materials for additive manufacturing in metals, enabling components with locally varying alloys for increased performance. At the end of the project, fundamental process mechanisms and resulting materials structures should have been evaluated and efficiency analysis for the process compared to other AM-processes executed. Also, concepts for fast multi material feeding will be developed.
Expected results and effects
There is a spoken interest by companies for Multi-Material Additive Manufacturing (MMAM). The impact of successful development of the process is in the long run expected to be of significance for the Swedish industry. This could be a new paradigm for design possibilities and cost efficient production of high value components. The project results will be the basis for future development of the process via follow up projects with the aim to come closer to commercial manufacturing of the system and end use for product development and industrial collaboration.
Planned approach and implementation
The project aims initially to answer issues about the process and later find means to further develop the concept closer towards implementation. By sufficient control the droplets can be placed next to one another while maintaining sufficient material properties in the transition regions, enabling multi voxel based material structures (voxel = 3D block vs pixel = 2D block). Aspects in the project is among others to investigate: process control for creating and driving of droplets, deposition rate, multi material concepts and transition regions for deposited droplets
