Manufacturing of ceramic components with a geometrically complex 3D architecture and highly detailed features for use in a variety of practical applications is still a challenge. In our investigation, we adopted a synergistic strategy for fabricating SiOC ceramics with intricate 3D morphologies by additive manufacturing and origami technique or assemblage, taking advantage of the high printability and flexibility of a commercially available silicone elastomer. Secondary shaping using origami of different 2D layers with varied design allowed the manufacturing of spiral, flower-like and polyhedron architectures, which are difficult to fabricate without adding supports or by any conventional ceramic fabrication processes. Produced samples showed no cracks or pores and fully retained the given shape after pyrolysis.

Abstract

Manufacturing of ceramic components with a geometrically complex 3D architecture and highly detailed features for use in a variety of practical applications is still a challenge. In our investigation, we adopted a synergistic strategy for fabricating SiOC ceramics with intricate 3D morphologies by additive manufacturing and origami technique or assemblage, taking advantage of the high printability and flexibility of a commercially available silicone elastomer. Secondary shaping using origami of different 2D layers with varied design allowed the manufacturing of spiral, flower-like and polyhedron architectures, which are difficult to fabricate without adding supports or by any conventional ceramic fabrication processes. Produced samples showed no cracks or pores and fully retained the given shape after pyrolysis.
