“…Specimens were printed using a DLP-based stereolithographic device (ADMAFLEX 130, ADMATEC Europe BV, The Netherlands). The main printing parameters were optimised to achieve a good quality printing, following our previous works [22]. Thus, layer thickness, exposure time and LED power were fixed at 30 m, 1000 ms and 250 ‰, respectively.…”

“…The commonly used high-strength materials are ZrO 2 , Al 2 O 3 , etc. Coppola et al 123 compounded Al 2 O 3 and ZrO 2 to obtain a high bending strength and elastic modulus (ranging between 415 and 843 MPa and 188 and 318 GPa, respectively) through DLP. The hardness values were higher than those of pure Al 2 O 3 samples, which was because ZrO 2 exerted effective pinning on the grain boundaries of Al 2 O 3 , thus avoiding the abnormal growth of Al 2 O 3 grains.…”

Treating bone defects is highly challenging because they do not heal on their own inside the patients, so implants are needed to assist in the reconstruction of the bone. Bioceramic implants based on additive manufacturing (AM) are currently emerging as promising treatment options for restoration bone engineering. On the one hand, additively manufactured bioceramic implants have excellent mechanical properties and biocompatibility, which are suitable for bone regeneration. On the other hand, the designable structure and adjustable pores of additively manufactured bioceramic implants allow them to promote suitable cell growth and tissue climbing. Herein, this review unfolds to introduce several frequently employed AM technologies for bioceramic implants. After that, advances in commonly used additively manufactured bioceramic implants, including bioinert ceramic implants, bioactive ceramic implants, and bioceramic/organic composite implants, are categorized and summarized. Finally, the future perspectives of additively manufactured bioceramic implants, in terms of mechanical performance improvement, innovative structural design, biological property enhancement, and other functionalization approaches, are proposed and forecasted. This review is believed to provide some fundamental understanding and cutting-edge knowledge for the additive manufacturing of bioceramic implants for restoration bone engineering.

“…The mechanical properties of nano-composites made using the DLP procedure were tested and related to those of reference materials such as basic zirconia and alumina. Temperatures of the sintering for each composite was tuned based on ending microstructural development and density, with the goal of achieving a target [9]. Rezaee and Ranjbar investigated the thermal conductivity confection of permeable Al2O3 20 wt.…”

The applications of nanotechnology differ in different areas of life. Despite all the advantages of nanomaterials, there are many difficulties that need further research the most important of which is obtaining cheap, practical materials with appropriate specifications for use in various applications. This study examines the addition of multiple proportions of two materials (Silicon Carbide and Zirconia) to 6261 Aluminum alloy. Results were obtained stating that using the two nano-materials together is better than using each one separately. The best ultimate tensile strength (UTS)waders were obtained at (1.5-2.0 wt%) ratios ranging. 1.5% wt. of ZrO2 and (%SiC+% ZrO2). The improvements were (75.1 %) and (92 %) respectively. The UTS improvements (84.3%) for Al/ 2.0wt. %SiC. Also, a significant improvement was seen in the hardness values for all the weight ratios of the nano-additives with respect to the base alloy. The percentage of ductility has decreased after adding nano-materials.
