A three-dimensional printing device to produce organs and tissues for transplant

摘要

Organ failure is a condition where an organ system not able to function as intended, preventing the body from maintaining homeostasis. An organ transplant replaces the patient's organ with a donated organ, but the procedure includes several risks, such as rejection or infection. Organ printers aim to eliminate some risks involved with organ transplantation by producing an organ from the patient's own cells. This organ printer uses a system of motors with three degrees of freedom controlled by a custom written algorithm. The printer will lay down polyethylene glycol and cells onto a biocompatible scaffold where the cells will combine and create a new tissue or organ. Tests will be performed to ensure nozzle precision and flow, speed of printing, and cell survivability.
