ABSTRACT
SUSTAINABLE BONE REPLACEMENT MATERIAL : ADDITIVE MANUFACTURING OF TCP-HAP-WOLLASTONITE COMPOSITE FOR TISSUE ENGINEERING APPLICATIONS
Additive manufacturing (AM) has emerged as a transformative technology, enabling the layer-by-layer construction of three-dimensional objects directly from digital models. Among its diverse applications, ceramic additive manufacturing holds considerable promise across various sectors, including medical, aerospace, and academia. This research specifically focuses on the utilization of Direct Ink Writing (DIW) or robocasting techniques for bio ceramic applications, particularly tri-calcium phosphate (TCP), hydroxyapatite (HAP) and wollastonite as a bone replacement material in Tissue Engineering (TE). Despite advancements in AM technologies, challenges persist in optimizing printability, necessitating thorough investigations into factors such as powder-to-binder and binder-water ratios, rheological properties, and alternative binder materials. The invention introduces a novel bone replacement material that is both cost-effective and sustainable, showcasing enhanced mechanical properties. This composite material is primarily composed of TCP, HAP, and wollastonite. A significant aspect of this development is the synthesis of HAP from orange peels, which exemplifies an environmentally friendly approach and aligns with the project’s motto, “GREEN PRINT HEALTH.” This innovative production method not only minimizes waste but also effectively reduces overall production costs. To comprehensively evaluate the properties of the TCP-HAP-wollastonite composite, a series of characterization tests were conducted. X-Ray Diffraction (XRD) analysis confirmed the crystalline phases present in the composite, while in vitro bioactivity assessments demonstrated the formation of a bone-like apatite layer on the surface upon immersion in simulated body fluid (SBF). The compressive strength of the composite scaffolds was evaluated, revealing enhanced mechanical properties with the addition of wollastonite. Cytocompatibility studies using human osteoblast-like cells (MG-63) indicated that the composite supported cell attachment, viability, and proliferation.
Through systematic exploration and experimentation, this study provides valuable insights into optimizing additive manufacturing processes for bio ceramic applications, thereby laying the groundwork for future advancements in the field of bone tissue engineering. The combination of bioactivity, enhanced mechanical properties, and controlled biodegradation makes this composite a viable candidate for further in vivo evaluation and clinical translation.
