About 15 years ago, bioprinting was coined as one of the ultimate solutions to engineer vascularized tissues, which was impossible to accomplish using the conventional tissue fabrication approaches. With the advances of 3D‐printing technology during the past decades, one may expect 3D bioprinting being developed as much as 3D printing. Unfortunately, this is not the case. The printing principles of bioprinting are dramatically different from those applied in industrialized 3D printing, as they have to take the living components into account. While the conventional 3D‐printing technologies are actually applied for biological or biomedical applications, true 3D bioprinting involving direct printing of cells and other biological substances for tissue reconstruction is still in its infancy. In this progress report, the current status of bioprinting in academia and industry is subjectively evaluated. The progress made is acknowledged, and the existing bottlenecks in bioprinting are discussed. Recent breakthroughs from a variety of associated fields, including mechanical engineering, robotic engineering, computing engineering, chemistry, material science, cellular biology, molecular biology, system control, and medicine may overcome some of these current bottlenecks. For this to happen, a convergence of these areas into a systemic research area “3D bioprinting” is needed to develop bioprinting as a viable approach for creating fully functional organs for standard clinical diagnosis and treatment including transplantation.
