By altering conventional 3D printing methods, bioprinting creates complex biological structures using living cells, biomolecules, and biomaterials. Bioinks take the role of ink, while biodegradable supports take the place of paper. Bioprinting is currently only \begin{table}

In order to create functioning tissues and organs for transplants or medication trials, tissue engineering has a great deal of promise with this cutting-edge manufacturing technique. Researchers at Rice University created a bio-additive manufacturing method that combines tissue engineering with bioprinting. They print tissue constructs with their own blood supply using a bioink made of stem cells, blood vessels, and hydrogel. These structures can develop into liver, cartilage, bone, and skin [46; 63; 64; 65]. Bioprinting for tissue regeneration has made significant strides in replicating tissues like skin, bone, and cartilage using 3D printing techniques. Key advancements include 3D-printed skin, which shows promise for wound healing, burn treatment, and in vitro testing. Researchers like [PERSON] and [PERSON] achieved high cell viability and survival rates by printing layered skin with keratinocytes and fibroblasts. [PERSON] et al. successfully implanted bioprinted skin into mice, while [PERSON] introduced a gelatin-chitosan hydrogel to improve printability and antimicrobial properties. [PERSON] advanced the field by bioprinting human bilayered skin that mimicked the structure and function of human skin. [PERSON]'s innovative strategy combined extrusion and inkjet bioprinting for 3D skin models, creating stable dermal and epidermal layers. [PERSON] developed gelatin-sulfonated silk scaffolds that enhanced skin regeneration and cell proliferation in animal models, demonstrating potential for clinical use. Bone bioprinting has emerged as a viable alternative to traditional bone grafting methods, addressing limitations such as graft availability, immunogenicity, and risk of disease transmission. Through 3D printing techniques, researchers have developed scaffolds that facilitate enhanced bone regeneration and promote cellular differentiation. For instance, [PERSON] et al. incorporated bone morphogenetic protein-2 (BMP-2) into 3D-printed poly (DL-lactic-co-glycolic acid) (PLGA) scaffolds, resulting in successful bone regeneration in rat models. [PERSON] et al. fabricated mechanically robust tricalcium phosphate (TCP) scaffolds, further enhancing their osteogenic properties through the addition of strontium and magnesium, which significantly improved osteogenesis and bone formation. Similarly, [PERSON] et al. created polycaprolactone (PCL) scaffolds with nano-structured pores, demonstrating effective osteointegration in animal studies.
