| Abstract Scope |
Silicon carbide (SiC) remains the material of choice for many industrial and energy applications at high temperatures. However, SiC can be difficult to shape and process to high density, especially by additive manufacturing. For materials with high refractive indexes, vat photopolymerization techniques remain difficult. Thus, alternative methods are being evaluated that utilize aqueous colloid SiC suspensions. This newer technique for ceramic green state 3D printing with alumina and preliminary results for SiC will be presented. The laser induced slip casting (LIS) technique requires a low viscosity slurry that can be dried in-situ with the laser to build up layers for a 3D printed part. Details of the requirements necessary for achieving this will be highlighted. In addition, preliminary mechanical and physical properties of sintered components will be discussed. These show that LIS technology has the potential to print ceramics with high light absorption and high refractive index at large scale. |
