“…Beam melting is a technique that uses a tungsten electron beam instead of laser to selectively melt metal powder particles layer by layer under vacuum conditions. Similarly, when facing critical bone defects, Abdullah et al [11] combined electron beam melting with piezoelectric BaTio 3 to create titanium alloy scaffolds with both biomechanical stability and electroactivity. The sintered Ti6Al4V lattice structure did not show significant deformation when combined The nozzle is versatile and flexible with multiple types.…”

“…The epidermal tissue of the skin has a gradient of porosity, and the muscle fibers in the cardiovascular system form structural gradients. The interface between cartilage and bone, bone and tendon, also shows structural and molecular gradients along the longitudinal axis [11]. There are different amounts and types of minerals in bone tissue, and the concentration of ion components such as sodium, potassium, and calcium in the extracellular matrix (ECM) exists in the form of compositional gradient.…”

“…It is, therefore, reasonable to transfer the piezoelectric properties of bone to engineered biomaterials and thus, facilitate bone regeneration in a biomimicry approach. Recent studies have explored the use of lead-free piezoelectric ceramics such as barium titanate (BaTiO 3 ) [ [35] , [36] , [37] , [38] , [39] , [40] , [41] , [42] ], lithium niobate (LN) [ [43] , [44] , [45] ], lithium potassium sodium niobate (LNKN) [ 23 , 46 , 47 ] and potassium sodium niobate (KNN) [ 48 , 49 ] showing enhanced protein adsorption on charged surfaces and increased cell proliferation and metabolic activity. Therefore, combining a piezoelectric ceramic which causes autonomous stimulation of bone cells through bioelectric cues with a classical bioactive material that leads to rapid biomineralisation in the interface is quite promising.…”
