“…Boccaccio et al suggested that the circular pore demonstrated a certain amount of mechanical properties when its porosity distribution law is varied [ 27 ]. A circular pore with a low amount of porosity also helps in ensuring a high amount of mechanical strength [ 28 ]. Although the porosity amount of a circular-shaped pore is high, its mechanical strength was lower in a study carried out by Jahir-Hussain et al [ 29 ].…”

The design of a scaffold of bone tissue engineering plays an important role in ensuring cell viability and cell growth. Therefore, it is a necessity to produce an ideal scaffold by predicting and simulating the properties of the scaffold. Hence, the computational method should be adopted since it has a huge potential to be used in the implementation of the scaffold of bone tissue engineering. To explore the field of computational method in the area of bone tissue engineering, this paper provides an overview of the usage of a computational method in designing a unit cell of bone tissue engineering scaffold. In order to design a unit cell of the scaffold, we discussed two categories of unit cells that can be used to design a feasible scaffold, which are non-parametric and parametric designs. These designs were later described and being categorised into multiple types according to their characteristics, such as circular structures and Triply Periodic Minimal Surface (TPMS) structures. The advantages and disadvantages of these designs were discussed. Moreover, this paper also represents some software that was used in simulating and designing the bone tissue scaffold. The challenges and future work recommendations had also been included in this paper.

“…According to Equation (1), a lower scanning speed increases the energy density and, therefore, increases the contact time between the laser and powder bed. The energy density window has to be carefully designed to achieve the desired functional scaffold for BTE [ 17 ].…”

“…It is also possible to temper the grain size of nano-HA from acicular to a near spherical or ellipsoidal shape to achieve partial or full melting [ 42 ]. The potential of SLM technology to fabricate CS/silicon bioactive ceramic composites with high compressive strength is unleashed [ 17 , 35 ], It is also possible to achieve higher hardness and good fracture toughness when HA is reinforced into the metal matrix [ 43 , 44 ]. Hence, SLM provides the freedom to interfere with the morphology of the powder because of the rapid heating and cooling process unfolding (solidification at a rate of 105–108 K/s) and to have an upper hand in the other AM processes with regards to superior mechanical properties.…”

“…Although CS bioceramics exhibit relatively higher mechanical properties as compared to CaP, these materials can hardly be used for cortical bone replacement or load-bearing applications. However, on the other hand, silicon-based CS bioactive ceramics fabricated through PBSLP with a large proportion of silicate in the composite can be used for load-bearing applications, also shown in Figure 8 [ 17 ].…”

The implementation of a powder bed selective laser processing (PBSLP) technique for bioactive ceramics, including selective laser sintering and melting (SLM/SLS), a laser powder bed fusion (L-PBF) approach is far more challenging when compared to its metallic and polymeric counterparts for the fabrication of biomedical materials. Direct PBSLP can offer binder-free fabrication of bioactive scaffolds without involving postprocessing techniques. This review explicitly focuses on the PBSLP technique for bioactive ceramics and encompasses a detailed overview of the PBSLP process and the general requirements and properties of the bioactive scaffolds for bone tissue growth. The bioactive ceramics enclosing calcium phosphate (CaP) and calcium silicates (CS) and their respective composite scaffolds processed through PBSLP are also extensively discussed. This review paper also categorizes the bone regeneration strategies of the bioactive scaffolds processed through PBSLP with the various modes of functionalization through the incorporation of drugs, stem cells, and growth factors to ameliorate critical-sized bone defects based on the fracture site length for personalized medicine.

“…[ 17,18 ] Powder bed fusion such as laser sintering (LS) uses a laser beam to sinter or fuse a thin layer of powders. [ 19,20 ] Currently, the raw materials employed for LS are mainly metal powders such as stainless steel, titanium, and aluminum. Material jetting deposits droplets of the build and support materials onto the platform, [ 21 ] while binder jetting fuses the powder materials with a liquid bonding agent.…”
