Researchers from both Rice University & Baylor College of Medicine have 3D printed capillaries that are actually capable of transporting blood to tissue. This process, known as tubulogenesis, allows for patient-specific cells to be extracted and will offer great potential for 3D printed organs. Immediately though, the researchers see their 3D printed capillaries offering great benefit to drug testing labs. Learn more at 3DPrint.com: http://3dprint.com/180632/rice-baylo...d-capillaries/
