Advances in 3D-Printed Surface-Modified Ca-Si Bioceramic Structures and Their Potential for Bone Tumor Therapy.

Traditional bioceramic scaffolds face limitations in achieving optimal structural complexity for photothermal therapy and drug delivery. These scaffolds are known for their mechanical stability and biocompatibility, making them suitable for bone regeneration and cancer treatment. However, conventional fabrication methods hinder the development of macro-, micro-, and nanostructures necessary for enhanced therapeutic outcomes. Researchers have explored alternative fabrication techniques to overcome these constraints. 3D printing has emerged as a promising solution, enabling precise control over scaffold architecture. This method supports the creation of complex geometries and reproducible structures. Surface modification of bioceramics remains a key challenge in maximizing their therapeutic potential. The need for scalable and sustainable fabrication methods has driven recent innovations in the field. This gap motivated the exploration of 3D printing as a novel approach for bioceramic scaffold development.

This review aims to evaluate the use of 3D printing for fabricating surface-modified calcium silicate (Ca-Si) bioceramic scaffolds. The goal is to assess how these scaffolds can be optimized for photothermal therapy and drug delivery in bone tumor treatment. The study focuses on the functionalization of both external and internal scaffold surfaces. Researchers sought to identify the most effective photothermal materials for integration into Ca-Si scaffolds. The review also examines how 3D printing enables precise control over scaffold architecture. The motivation stems from the limitations of traditional synthesis methods in achieving structural complexity. The study highlights the potential of 3D-printed Ca-Si as a dual-function platform for cancer treatment and tissue regeneration. This approach addresses the need for scalable and reproducible fabrication techniques in biomedical applications.
