代替タイトル: Binder Jetting Technology for Structural Ceramics: Process Development and Sintered Density Improvement

説明:

This study introduces the Particle Homogenization Modeling (PHM) method, an advanced binder jetting approach for structural ceramics. Targeting applications that demand high reliability, the method improves strength through optimized densification and defect reduction. Flexural strength tests and Weibull analysis revealed that low-strength fractures originate from poorly sintered grain boundaries, while higher strength specimens fractured from spherical defects. At strengths exceeding 300 MPa, fewer spherical defects were observed, correlating with densities above 96%. Comparison with other additive manufacturing techniques highlights PHM’s advantage in fabricating dense and reliable ceramic components. This report discusses processing optimization, defect origins, and performance benchmarking against other additive manufacturing methods.
