“…19 However, fine powder can agglomerate due to attractive interactions between spherical particles (van der Waals forces) 21 that can dominate gravitational forces and reduce flowability, resulting in poor compaction and unacceptable powder bed recoating. However, Butscher et al 21 also subjected their fine powder to plasma treatment with monomer hexamethyldisiloxane, which deposited tiny point -like nanostructures on the powder surface that acted as spacers between the nanoparticles, increased the interparticle distance, reduced van der Waals forces, and improved flowability. Thus, a trade -off between flowability and resolution is unavoidable.…”

“…Seitz et al 22 recommends using spherical granules (e.g., CaP) of mean diameter below 100 μ m to ensure good resolution. Butscher et al 21 conducted a systematic evaluation of powder properties such as powder size and flowability in order to better understand the effect of these characteristics on printability of CaP. They fabricated and tested CaP powders of 6, 18, 29, 35, and 50 μ m size.…”

“…The most relevant RP techniques in the design of 3D scaffolds for tissue engineering are 3D printing (3DP), selective laser sintering (SLS), stereolithography (SLA), robocasting (RC), and Figure 6 shows a schematic diagram of the processing of each RP based-technique [80].…”

Millions of peoples in the world suffer from their bone damage tissues by disease or trauma. Every day, thousands of surgical procedures are performed to replace or repair these tissues. The availability of these tissues is a big problem, and their costs are expensive. The repair of these defects has become a major clinical and socioeconomic need with the increase of aging population and social development. The emerge of tissue engineering (TE) is considered as a glimmer of hope to contribute in solving this problem. It aims at the regeneration of damaged tissues with restoring and maintaining the function of human bone tissues using the combination of cell biology, materials science, and engineering principles. In this chapter, the current state of the tissue engineering in particular bioceramic scaffolds was discussed. Concept of tissue engineering was explored. Bioceramic scaffold materials, their processing techniques, challenges taken into consideration the design of the scaffolds, and their in-vitro and in-vivo studies were highlighted. The scaffolds with extra-functionalities such as drug release ability and clinical applications were mentioned.

“…By the end of the printing process, another stage is needed, to remove the excess dust in the object, using compressed air [54]. The term "3D printability" was first defined by Butscher and collaborators (2012) as "powder characteristics essential for the 3DP process" and it intrinsically depend on: (1) powder topology, including particle size, particle size distribution, morphology and specific surface area and (2) material reactivity with the binder [123]. Among the powder topological characteristics, particle size has been demonstrated as the dominant factor in determining the quality of printed products [200].…”

Due to the high incidence of bone fractures in the population, it became necessary to produce scaffolds that are able to assist in tissue regeneration. It is necessary to find an appropriate balance between the mechanical and biological properties, in order to mimic the natural tissue, these properties are directly related to the architecture and their degree of porosity, as well as the size of their pores and their interconnectivity. In this perspective, the 3D printing stands out, where the structure is obtained layer by layer, according to a predetermined computational model which provides a greater control of architecture and scaffold geometry and overcomes, in this way, the limitations of traditional techniques of scaffolds manufacturing. In this way, the objective of this seminar is to present the state of the art of the polymer scaffolds produced by 3D printing and applied to bone tissue regeneration, highlighting the advantages and limitations of this process.
