3D printer manufacturing mini ****

Today's 3D printers have revolutionized the medical community. Recently, a U.S. company used 3D printing to create miniature liver organs with a depth of 0.5 mm and a width of 4 mm. Miniature livers produce albumin.

Organovo produced about 20 layers of living cells layer-by-layer using a 3D printer with two print heads to create this miniature organ. A print head of a 3D printer is responsible for printing scaffolds, and another print head prints human cells layer by layer to form an organ structure.

The printed organ has several major functions of a real liver organ, such as the production of proteins that transport hormones, delivery of salts and drugs throughout the body, and delivery of nutrients and oxygen, which can accompany cells from the blood vessels to the liver. Miniature liver organs are a great improvement compared to 2D cultured cells. Not only are the functions more complete, but the number of surviving days is also greatly increased. This 3D honeycomb can survive for more than 5 days.

This has a positive effect on the study of infectious diseases and also has a major impact on the monitoring of drug therapy. For some familial genetic diseases that are closely related to the lack of proteins, micro-hepatic organs will balance the protein in the body and have a tremendous role in the treatment of disease research. At present, scientists are printing larger blood vessel networks to nourish the actual size of human organ tissue.
