3D Printing easy diagnose and replace parts
At the beginning of 2015, Ray Flynn couldn’t see a thing in front of him. The 80-year-old suffered from a common disease called dry age-related macular degeneration (AMD), which caused him to lose his central line of sight and required him to rely on his peripheral vision instead. Flynn couldn’t use ATMs and had trouble distinguishing weeds from flowers in his garden. But in June, Flynn received the world’s first retinal implant to treat AMD, a procedure that left the patient with a bonafide bionic eye.
According to the researchers and Michael McAlpine, a co-author of the study and professor at the University of Minnesota at the University of Minnesota,” we were able to 3D-print on a hemispherical surface an array of light receptors. Published in the journal Advanced Materials on Tuesday, the study is the first to reveal a way to create a 3D-printed bionic eye with this method.
Bionic eyes are usually thought of as science fiction, but now we are closer than ever using a multi-material 3D printer he also mention that we have a long way to go to routinely print active electronics reliably, but our 3D-printed semiconductors are now starting to show that they could potentially rival the efficiency of semiconducting devices fabricated in micro-fabrication facilities plus, we can easily print a semiconducting device on a curved surface, and they can’t.”
This is incredible to know about the placenta. the placenta is the most important part of pregnancy. I wish they had this discovery before.
It’s fine now we all know. I had complete placenta previa.
Since then really wanted to know more aggressively about new researches regarding placenta:)
Artificial placenta created in the laboratory
Complex substance exchange between mother and child
“The transport of substances through biological membranes plays an important role in various areas of medicine”, says Prof. Aleksandr Ovsianikov of the Institute of Materials Science and Technology at TU Wien. “These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”
The placenta protects the infant by filtering out harmful substances while allowing others to pass through with ease. The Austrian scientists have now mimicked the natural processes that created the placenta with the help of novel, laser-based 3D printing process. The researchers claimed the artificial material is the closest scientists have come to replicating the fundamental human organ. Professor Aleksandr Ovsianikov, Institute of Materials Science and Technology in Vienna, said the placenta is a vital element of the human body. The expert said: “The transport system of substances through biological membranes plays an important role in various areas of medicine. “These include the blood-brain barrier, ingestion of food in the stomach and intestine, and also the placenta.”
My Father In-law was the famous surgeon for doing cleft lip surgery. According to the Scientific Reports volume,”Computer-aided design and computer-aided manufacturing (CAD/CAM) technology have been implemented in the treatment of cleft lip and palates (CLP) by several research groups. This pilot study presents a technique that combines intraoral moulding with a semi-automated plate generation and 3D-printing”.
