With the help of Stratasys 3D printers a UK based company called Brightwake Ltd. have been able to produce a machine which recovers lost blood from a patient during surgery in a way that allows the blood to be transfused back into the body. This is great news for people with religious beleifs that cause them to be unable to recieve blood transfusions. It is also great news for people with very rare blood types that may require emergency surgery but their hospital is under-supplied with their rare blood type for whatever reason. This device could help save their lives, and the lives of many others. Just another way additive manufacturing is helping the world change in positive ways.
