| Abstract Scope |
Stereolithography (SLA) based 3D printing offers a unique platform to fabricate ceramic-polymer composites in a discrete layer by layer manner, with unique capability to realize complex geometries and structural architectures. Critical to successful SLA printing for ceramic is to have a homogenous and stable suspension. We activated the surface of Silicone Carbide (SiC) and report on the integration of surface activated SiC with photocurable acrylic based polymer matrix for developing 3D ceramic objects with densified microstructure. The surface activated SiC has a higher affinity to bond with acrylic polymer, resulting in a uniform distribution of the SiC particles in the polymer matrix that eliminates the ceramic aggregation The ceramic filler volume ratio has been correlated to the 3D printed part characteristics i.e., porosity and density. The subsequent sintering of the 3D printed surface activated SiC object results in silica nanowire growth inside the pores leading to high densification. |
