“…Silicon has already displayed its potential in biocalcification, biomineralization, osteogenesis, and BTE [ 151 , 152 , 153 ]. The potential of pure silicon in the powder bed through Nd:YAG laser interaction was also unveiled [ 154 ]. Apart from the earthbound silica-based biomaterial applications in the biomedical sector, silica-based material research through SLM has been further extended to other extraterrestrial planets like the Moon and Mars because of their abundance [ 155 ].…”

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.

“…SLS has some strengths over other additive manufacturing techniques, for instance, materials can be reused and high-precision parts can be fabricated [ 8 ]. At present, the powder materials applied in SLS technology mainly focus on metals composites [ 9 , 10 , 11 ], ceramics composites [ 12 , 13 ], and polymers composites [ 14 , 15 , 16 , 17 ]. Because most SLS materials have high cost, the research and development of new powder materials suitable for SLS technology have become a hot spot in current research.…”

The agricultural and forestry waste walnut shell and copolyester hot-melt adhesives (Co-PES) powder were selected as feedstock. A kind of low-cost, low-power consumption, and environmentally friendly walnut shell/Co-PES powder composites (WSPC) was used for selective laser sintering (SLS). Though analyzing the size and morphology of walnut shell particle (≤550 μm) as well as performing an analysis of surface roughness, density, and mechanical test of WSPC parts with different particle sizes, results showed that the optimal mechanical performance (tensile strength of 2.011 MPa, bending strength of 3.5 MPa, impact strength of 0.718 KJ/m2) as walnut shell powder particle size was 80 to 120 μm. When walnut shell powder particle diameter was 120 to 180 μm, the minimum value of surface roughness of WSPC parts was 15.711 μm and density was approximately the maximum (0.926 g/cm3).
