“…They found that encapsulation of Mg aids in the sintering and compactness of CaSi bioceramics, like AK, and reduces dissolution rate, as well as modifies the compressive and flexural strength of CaSi porous scaffolds. 43 In fact, AK with low fracture toughness cannot meet the requiring range of cortical bone that restricts its biomedical application. One viable solution is to add a second phase into the matrix as fillers, such as boron nitride nanosheets (BNNSs) with a great elastic modulus and significant specific surface area.…”

“…The focus on the magnitude of heat treatment temperature and time on the resulting structures was a common theme recorded in previous studies. 43 MgO, SiO 2 , and eggshell (as a calcium base) powders were employed as initial components by Najafinezhad et al 44 For the fabrication of akermanite powders, the raw materials mixture was ball milled for 6 h in a planetary ball mill. Duman et al 45 employed a couple of approaches to prepare akermanite powders, such as sol-gel, ball-milling, and spray drying accompanied by heat treatment.…”

The need for operative treatment also comes from injury, degeneration, and illnesses. This typically includes removing skeletal components such as ankles, legs, finger joints, wrists, vertebrae, jaws, and other essential organ systems such as the liver, heart, skin, etc. 1 These materials are indicative as a distinctive group of biomedical well-designed materials that most likely conducted a wide range of biological functions in the absence of the specific living tissue/organ, as a consequence, replace the issues found with the defective tissue/ organ and assist the living organism. 1,2 These structural and

“…In polymer materials, poly-l-lactide (PLLA) is widely used because of its good biocompatibility [39][40][41]. However, the traditional scaffold preparation methods usually struggle to realize the personalized customization of the macroscopic and internal structure of the scaffold simultaneously [42,43]. The introduction of 3D printing technology has effectively solved this problem.…”

Tissue engineering is one of the most effective ways to treat bone defects in recent years. However, current highly active bone tissue engineering (BTE) scaffolds are mainly based on the addition of active biological components (such as growth factors) to promote bone repair. High cost, easy inactivation and complex regulatory requirements greatly limit their practical applications. In addition, conventional fabrication methods make it difficult to meet the needs of personalized customization for the macroscopic and internal structure of tissue engineering scaffolds. Herein, this paper proposes to select five natural biominerals (eggshell, pearl, turtle shell, degelatinated deer antler and cuttlebone) with widely available sources, low price and potential osteo-inductive activity as functional particles. Subsequently compounding them into L-polylactic acid (PLLA) biomaterial ink to further explore 3D printing processes of the composite scaffold, and reveal their potential as biomimetic 3D scaffolds for bone tissue repair. The research results of this project provide a new idea for the construction of a 3D scaffold with growth-factor-free biomimetic structure, personalized customization ability and osteo-inductive activity.
