“…In this section, GelMA will be used as a photosensitive hydrogel bioink to verify the printing ability of the cell 3D printing system developed in this paper in terms of photosensitive ink. The previous work has introduced the effect of UV light irradiation on the biological activity of the cells in printed structures when GelMA is used as a bioink[ 61 , 62 ]. Therefore, this section uses the previous experimental conclusions to directly verify the structure printing capability of the system and the cell survival rate after printing.…”

Three-dimensional (3D) bioprinting offers a potentially powerful new approach to reverse engineering human pathophysiology to address the problem of developing more biomimetic experimental systems. Human tissues and organs are multiscale and multi-material structures. The greatest challenge for organ printing is the complexity of the structural elements, from the shape of the macroscopic structure to the details of the nanostructure. A highly bionic tissue-organ model requires the use of multiple printing processes. Some printers with multiple nozzles and multiple processes are currently reported. However, the bulk volume, which is inconvenient to move, and the high cost of these printing systems limits the expansion of their applications. Scientists urgently need a multifunctional miniaturized 3D bioprinter. In this study, a portable multifunctional 3D bioprinting system was built based on a modular design and a custom written operating application. Using this platform, constructs with detailed surface structures, hollow structures, and multiscale complex tissue analogs were successfully printed using commercial polymers and a series of hydrogel-based inks. With further development, this portable, modular, low-cost, and easy-to-use Bluetooth-enabled 3D printer promises exciting opportunities for resource-constrained application scenarios, not only in biomedical engineering but also in the education field and may be used in space experiments.

“…TC4 alloy is one of the most researched and widely used materials for SLM molding because of its high specific strength, good corrosion resistance and biocompatibility properties. SLM TC4 alloy formed components had been used in areas such as space engines and biological implant materials [4][5][6][7][8][9].…”

In the selective laser melting (SLM) technology, the microstructure and mechanical properties of the sample were affected by the building direction. In this paper, the effects of building direction on the microstructure and mechanical properties of SLM TC4 alloy were investigated of using optical microscope, scanning electron microscope, microhardness tester and MTS-Landmar material testing machine. The results show that the microstructure of SLM TC4 alloy consists of acicular martensitic α′ phase. The microstructure of SLM TC4 alloy in the horizontal build direction (H) was observed to have “checkerboard” shape, while the microstructure of SLM TC4 alloy in the vertical build direction (V) was observed to have column shape. The microhardness of SLM TC4 alloy with different building directions are almost the same and the tensile properties are different. The yield and tensile strengths of sample H are higher at 995.5 MPa and 1139.3 MPa, but the fracture elongation of sample V is better at 10.3%. The fracture mechanism of SLM TC4 alloy is ductile fracture and the V sample has large and deep dimples.
