The advanced pressure assisted sintering techniques, such as spark plasma sintering, are very useful for the fabrication of high performance materials, but their main drawback are the difficulties to generate complex shapes. To address this problem a new processing approach enabling the integration of the advanced complex shapes-rendering methods of 3D printing and the high quality of the material microstructures obtained by the pressure assisted sintering techniques is developed.
The advantages of the new powder shaping and consolidation technique include the possibility to generate fully dense very high complexity shapes based on the use of 3D printing, the possibility to fabricate high performance materials, using consolidation techniques like spark plasma sintering or hot pressing, and the possibility to generate multiple parts by sintering them simultaneously thereby considerably increasing the productivity of the method.
Examples of the fabrication of complex shape components based on metallic or ceramic powders are provided.
