“…Given that these 3D-printing scaffolds only have pores formed by the extrusion lines, DIW has also been combined with other conventional pore-forming strategies, such as freeze casting, emulsion, and sacrificial templating, to create hierarchical porous ceramic scaffolds with both large porous frameworks and porous structures in the extrusion lines. 428,429 Feng et al utilized a modified nozzle to fabricate a biomimetic 3D-printing akermanite scaffold with lotus root-like structures. 430 Bredigite scaffolds with a similar hollow-pipe-packed structure and an external diameter of 1 mm and internal dimeter of 500 μm were also directly printed for vascularized bone regeneration (Fig.…”

“…Porous silicon nitride [ 21 ] excels by a unique combination of various mechanical, thermal, chemical, and electric properties such as its light weight, high strain and damage tolerance, high hardness and wear resistance, low thermal expansion coefficient, high-temperature resistance, good thermal shock resistance, oxidation and corrosion resistance, good biocompatibility, and favorable dielectric properties. Its fabrication routes include pressureless sintering [ 27 ], freeze drying [ 28 ], gel casting [ 29 , 30 ], the addition of sacrificial pore formers [ 31 ], the use of replica templates [ 32 ], three-dimensional printing [ 33 ], slip [ 34 ] and tape casting [ 35 ], microwave sintering [ 36 ], and other techniques.…”

Silicon nitride ceramics excel by superior mechanical, thermal, and chemical properties that render the material suitable for applications in several technologically challenging fields. In addition to high temperature, high stress applications have been implemented in aerospace gas turbines and internal combustion engines as well as in tools for metal manufacturing, forming, and machining. During the past few decades, extensive research has been performed to make silicon nitride suitable for use in a variety of biomedical applications. This contribution discusses the structure–property–application relations of silicon nitride. A comparison with traditional oxide-based ceramics confirms that the advantageous mechanical and biomedical properties of silicon nitride are based on a high proportion of covalent bonds. The present biomedical applications are reviewed here, which include intervertebral spacers, orthopedic and dental implants, antibacterial and antiviral applications, and photonic parts for medical diagnostics.

“…In practice, introduction of micropores that exist within the material is also of high interest for many applications. Therefore, in recent years, more effort has been given to combine macropores and micropores to introduce bimodal pore distribution 14,22 . Furthermore, it has been reported that integration of traditional methods into AM may allow controlling the size distribution, orientation, and uniformity of the combination of macropores and micropores 22 .…”

The interest on porous ceramics has increased in the last years with the developments in additive manufacturing methods, enabling design of components with complex geometries for membranes, filters, catalytic converters, or biostructures. In this study, porous alumina samples were produced by using different concentrations of poly(methyl methacrylate) as pore‐forming agent in a photocurable slurry via vat photopolymerization. The effect of layer thickness, poly(methyl methacrylate) particle size and sintering temperature on the mechanical properties and microstructural features of the samples was investigated as a function of poly (methyl methacrylate) concentration.. It is shown that the mechanical properties of 3D‐printed porous alumina are comparable with those fabricated by conventional processes. The Young's modulus, fracture toughness as well as the biaxial strength decreased with increasing weight concentration of pore forming agent (resulting in an increased total porosity). Specially using smaller poly(methyl methacrylate) particles has a positive effect, resulting in higher Young's modulus as well as fracture toughness. The feasibility of vat photopolymerization for fabricating novel parts with more complex porosity regions is explored by printing multi‐material samples and porosity graded architectures. The counterbalance effect between porosity and mechanical properties may be optimized by tailoring material composition and processing parameters.This article is protected by copyright.
