For example, the spinning of fibres, casting of thin films and the molding of complex shapes.
Commonly used preceramic polymers include polycarbosilanes and polysiloxanes, which transform through pyrolysis to SiC and SiOC type ceramics respectively.
[4] This process works with fused filament fabrication (FFF)-based 3-D printing to make fully dense cellular structures,[5] which can be used for scaffolds for bone regeneration that need to be mechanically stable and have a 3D architecture with interconnected pores.
[6] Various other 3D printing techniques (e.g., stereolithography, digital light processing, and two-photon polymerization) that are compatible with this strategy have so far been widely investigated.
[7] For example, through photopolymerization methods, preceramic polymers can be used in stereolithography approaches, enabling the additive manufacturing of complex shaped ceramic objects.
