Recent years have witnessed surging demand for bone repair/regeneration implants due to the increasing number of bone defects caused by trauma, cancer, infection, and arthritis worldwide. In addition to bone autografts and allografts, biomaterial substitutes have been widely used in clinical practice. Personalized implants with precise and personalized control of shape, porosity, composition, surface chemistry, and mechanical properties will greatly facilitate the regeneration of bone tissue and satiate the clinical needs. Additive manufacturing (AM) techniques, also known as 3D printing, are drawing fast growing attention in the fabrication of implants or scaffolding materials due to their capability of manufacturing complex and irregularly shaped scaffolds in repairing bone defects in clinical practice. This review aims to provide a comprehensive overview of recent progress in the development of materials and techniques used in the additive manufacturing of bone scaffolds. In addition, clinical application, pre-clinical trials and future prospects of AM based bone implants are also summarized and discussed.

Anionic homo- and copolymerization of p-diethynylbenzene in the presence of n-BuLi in polar solvents was carried out. The use of hexamethylphosphortriamide (HMPA) makes it possible to synthesize a completely linear soluble polymer that does not have branching and phenylene fragments. A copolymer of p-diethynylbenzene with diphenyldiacetylene was synthesized. Homo- and copolymers of p-diethynylbenzene have high thermo- and thermo-oxidative stability. By the interaction of side reactive ethynylphenylene groups with various reagents, it is proposed to synthesize clusters along the conducting chain of poly-p-diethynylbenzene. Due to presenting C≡CH side groups, boron, copper, and cobalt derivatives were synthesized. It is shown that not all theoretically possible stereoisomers can be formed as a result of the polymerization. The application of p-diethynylbenzene polymers for the modification of industrial samples of epoxy novolac resin, oligoester acrylates, and carbon fibers has been demonstrated.

“…Another way to obtain porous polymer materials is the PPC curing in the presence of a nonreactive component (NC), which does not participate in the polymerization reaction and is incompatible with the polymer 1,8,27–35 . After NC removal from in the polymer matrix, pores remain, and their parameters are determined by the nature and amount of the pore‐generating additive.…”

“…After NC removal from in the polymer matrix, pores remain, and their parameters are determined by the nature and amount of the pore‐generating additive. Moreover, from the PPC based on polyfunctional monomers, depending on the initial content of NC, it is possible to create both a porous and a monolithic polymer 1,27,35 . By acting with inhomogeneous light, or by moving illumination boundary, it is possible to form spatial distribution of the NC concentration, and, consequently, to vary the structure of the resulting polymer 36–42 .…”

The possibility of optically forming adjacent monolithic and porous fragments of a given geometry in a photopolymer layer by scanning stereolithography is considered. Using computer simulation of the diffusion process during such photo‐curing, the optimal modes of scanning with a light spot both for obtaining a monolithic polymer and for implementing the self‐formation of a porous structure in one photopolymerizable composition with a nonreactive component are determined. The results of experiments on the creation of porous polymer layers reinforced with monolithic stiffeners made from polyfunctional monomers using a scanning polymerizing spot with a diameter exceeding the pore size are presented.
