Assembly Three Dimensional Bismuth Titanate (3d-Bit) By Extrusion-Based Fuse Deposition Modeling Technique

Abstract
Bismuth Titanate (Bi4Ti3O12, BiT) are synthesized via sol-gel technique and combined with polyvinylpyrolidone (PVP) to obtain a thick paste composite for three dimensional shaping by extrusion-based fuse deposition modeling (FDM) technique. The phase compositions were investigated by X-ray diffractometry (XRD). Dilatometry measurement was performed to find out the suitable sintering temperature. Single phase with orthorhombic structure of BiT was obtained after calcination at 850˚C for 1h. The thick paste with different % vol. of PVP (1.0, 3.0, 7.5, 20% vol.) before printing was evaluated by rheology to optimize the extrusion condition. At 3.0% vol. of PVP, the printing speed of thick paste material was enlarged over 50% of BiT gel. Keywords: 3D printing, Bi4Ti3O12, Rheology, Sintering
