| Abstract | ||||
| Ceramic additive manufacturing (AM) has emerged as a transformative alternative to traditional fabrication methods, offering unparalleled design freedom and customization. This study compares two AM techniques Binder Jetting (BJ) and Selective Laser Sintering (SLS) for ceramic part production, evaluating their process mechanisms, material compatibility, post-processing requirements, and applications. BJ excels in scalability and complex geometries, utilizing inkjet-based binder deposition to achieve high-speed printing without support structures, though it necessitates extensive post-processing (e.g., sintering, infiltration) to enhance density. In contrast, SLS employs laser-driven powder fusion, enabling finer feature resolution but requiring high-energy inputs and polymer binders for ceramics, followed by thermal treatments to reduce porosity. The comparison includes BJ’s superior design flexibility and SLS’s higher precision, with material choices (e.g., alumina, SiC, hydroxyapatite) influencing mechanical properties and shrinkage behaviour. The paper highlights BJ’s dominance in biomedical scaffolds and large structural components, while SLS proves effectiveness for high-performance applications demanding tight tolerances. By addressing differences such as shrinkage control and densification, the research tries to analyse the fundamental differences in how BJ (inkjet-based binder deposition) and SLS (laser-based powder fusion) build ceramic parts layer by layer. | ||||
