Progress has been made in this area at Rice University, where researchers designed a 3D printer to make vessels in biocompatible hydrogels and designed a model of lungs that can oxygenate blood. [42] However, accompanied with this technique is the challenge of replicating the other minute details of organs. [ 42 ]
Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
Because a microfluidic lung-on-a-chip can more exactly reproduce the mechanical properties of a living human lung, its physiological responses will be quicker and more accurate than a Transwell culture system. Nevertheless, published studies admit that responses of a lung-on-a-chip do not yet fully reproduce the responses of native alveolar ...
By 2014, there had been various tissues regenerated by the 3D printer and these tissues included: muscle, vagina, penis and the thymus. In 2014, a conceptual human lung was first bioengineered in the lab. [16] [17] In 2015, the lab robustly tested its technique and regenerated a pig lung.

Magnetic 3D bioprinting is an alternative to other 3D printing methods such as extrusion, photolithography, and stereolithography.Benefits of the technique include its rapid process (15 minutes – 1 hour), compared to the often days-long processes of others, [4] [5] the capacity for endogenous synthesis of extracellular matrix (ECM) without the need for an artificial protein substrate and ...

Volume segmentation include automatic bone removal, such as used in the right image in this CT angiography. Volume segmentation of a 3D-rendered CT scan of the thorax: The anterior thoracic wall, the airways and the pulmonary vessels anterior to the root of the lung have been digitally removed in order to visualize thoracic contents:
