“…In this procedure, a negative mold is generated by one of the SFF fabrication techniques (e.g., stereolithographic working principles [220], the 3D printing system Model Maker II [222,223]) as a first step. In the second step, the scaffold is formed by adding the casting solution [224] to the negative mold using the desired polymeric and/or ceramic biomaterials. After solidification, the negative mold is removed by dissolution, melting or other procedures (FIGURE 6) [225].…”

Polymeric scaffolds for tissue engineering can be prepared with a multitude of different techniques. Many diverse approaches have recently been under development. The adaptation of conventional preparation methods, such as electrospinning, induced phase separation of polymer solutions or porogen leaching, which were developed originally for other research areas, are described. In addition, the utilization of novel fabrication techniques, such as rapid prototyping or solid free-form procedures, with their many different methods to generate or to embody scaffold structures or the usage of selfassembly systems that mimic the properties of the extracellular matrix are also described. These methods are reviewed and evaluated with specific regard to their utility in the area of tissue engineering.Expert Rev. Med. Devices 3(6), 835-851 (2006) The technology of tissue engineering aims to generate new or substitute damaged or malfunctioning tissue or organs and could well become an alternative method to whole organ transplantation [1][2][3][4][5][6]. In the last decade particularly, enormous advances have been made in the area of tissue regeneration for therapeutical purposes. Tissue engineering is an interdisciplinary research area in which principles of material science/engineering and cell biology/life science are combined. The methods of tissue engineering have been applied to different types of tissue, including skin [7][8][9][10][11], bone [12][13][14][15][16], liver [17][18][19][20][21], intestine [22][23][24][25][26][27], esophagus [28][29][30][31][32], valve leaflets [33][34][35][36], muscle [37][38][39] and tongue [40][41][42], the vascular system [43][44][45][46][47], for craniofacial defects [48][49][50], tendons and ligaments [51][52][53][54][55], cartilage [56][57][58][59][60] and nerve tissue [61][62][63][64][65]. Since the early commercialization of tissue-engineered applications, for example, the work of Bell and colleagues [66], research with stem cells [3,[67][68][69] and the use of growth factors [70][71][72][73] that support cell differentiation and proliferation, have provided new opportunities in the field of tissue engineering. At present, tissue engineering methods generally require the use of a porous scaffold that serves as a matrix for initial cell attachment and subsequently for tissue formation in vitro and in vivo. Up to now scaffolds made from biomaterials have temporarily substituted the extracellular matrix (ECM). Such biomaterials can be of natural origin, such as organic collagen [74][75][76], fibrin glue [77][78][79], hyaluronic acid [80][81][82] or the inorganic-like coralline [83,84]. Synthetic polymeric materials have also been investigated, including, for example, aliphatic, copolyesters [85][86][87], polyhydroxyalkanoates [88][89][90] and polyethylene glycol [91,92], or inorganic materials, such as hydroxyapatite [48,93,94], tricalciumphosphate [95,96], glass ceramics and glass [97][98][99].The intrinsic material properties, such as the mechanical [100] or thermal [101,102] be...

“…Comparing with the traditional metal or polymethyl methacrylate (mechanical and semimechanical) bone repair materials, most of the 3D printed bone repair materials have two obvious characteristics: one is made of biodegradable polymers, and the other is having go-through channels or pores. The predefined channels in the 3D printed construct are useful for nutrient supply and metabolite elimination for the in-growth of osteoblasts [69][70][71][72][73] . Some of the bone repair materials have showed good osteogenic effects and bone formation capabilities.…”

Three dimensional (3D) printing is a hot topic in today's scientific, technological and commercial areas. It is recognized as the main field which promotes "the Third Industrial Revolution". Recently, human organ 3D bioprinting has been put forward into equity market as a concept stock and attracted a lot of attention. A large number of outstanding scientists have flung themselves into this field and made some remarkable headways. Nevertheless, organ 3D bioprinting is a sophisticated manufacture procedure which needs profound scientific/technological backgrounds/knowledges to accomplish. Especially, large organ 3D bioprinting encounters enormous difficulties and challenges. One of them is to build implantable branched vascular networks in a predefined 3D construct. At present, organ 3D bioprinting still in its infancy and a great deal of work needs to be done. Here we briefly overview some of the achievements of 3D bioprinting technologies in large organ, such as the bone, liver, heart, cartilage and skin, manufacturing.Keywords: organ; 3D bioprinting; bone; heart; liver; cartilage; skin

Three-dimensional (3D) printing technology has been widely used in various manufacturing operations including automotive, defence and space industries. 3D printing has the advantages of personalization, flexibility and high resolution, and is therefore becoming increasingly visible in the high-tech fields. Three-dimensional bio-printing technology also holds promise for future use in medical applications. At present 3D bio-printing is mainly used for simulating and reconstructing some hard tissues or for preparing drug-delivery systems in the medical area. The fabrication of 3D structures with living cells and bioactive moieties spatially distributed throughout will be realisable. Fabrication of complex tissues and organs is still at the exploratory stage. This review summarize the development of 3D bio-printing and its potential in medical applications, as well as discussing the current challenges faced by 3D bio-printing.
