3D-Print Eyes(bonafide eye)

Posted on Updated on

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.”

3D printed Swiss watch

Posted on Updated on

We all love to have unique things. It is human nature.
When we visited Europe, I bought the Swiss watch at the Geneva airport.
The watch had the unique color. I never ever find that watch here in the USA before.
Recently when I was shopping at the mall. I visited Swiss watch store. I love shopping. You know what did I found. The same watch I bought at the airport. I can’t believe it.

Some people who were working for the store told me this is only for Geneva.

It is fine. We can get 3D printed watch, any color, any style:)
According to Bellouard and TAG Heuer Chief Executive Officer Jean-Claude Biver says”A personalized watch—a certain type of watch for one single person—would certainly be added value, and people would buy it for that, so the price could go up. Simplified manufacturing by reducing the number of components could also make it cheaper in certain aspects of transition is still in the beginning stages. Customers are increasingly looking for bespoke and unique pieces.”

3D print one of the strongest materials on Earth

Posted on Updated on

According to Xiaoyu “Rayne” Zheng and “Hensleigh”, assistant professor with the Department of Mechanical Engineering in the College of Engineering and director of the Advanced Manufacturing and Metamaterials Lab,“Now a designer can design three-dimensional topology comprised of interconnected graphene sheets. This new design and manufacturing freedom will lead to optimization of strength, conductivity, mass transport, strength, and weight density that are not achievable in graphene aerogels.
We’ve been able to show you can make a complex, three-dimensional architecture of graphene while still preserving some of its intrinsic prime properties, Usually, when you try to 3D print graphene or scale up, you lose most of their lucrative mechanical properties found in its single sheet form. It’s a significant breakthrough compared to what’s been done, We can access pretty much any desired structure you want”.

3D-printed lattice for bone repair

Posted on Updated on

When I was a little kid, one of my foot had the plaster cast for 2 months, I was unable to walk properly because it was stiff and thick.
I think it will be good for people who need a cast for any injury.
Some of the comments on the video, I am using different video and different comments for my post.

I am giving you just an idea.
Please check the link for more information. I can’t find the video for those things.
The biggest problem with this is the holes in the cast. I recently have a broken scaphoid and they cut a hole in the cast as a port for a bone stimulator. They had to fashion a plug for the hole and I need to wear a tensor bandage there to keep the swelling from pushing out at the hole. A cast doesn’t have holes in it for a very good reason – to contain swelling. No Doctor would design this.
This is just another use of a 3D printer, that’s all and it is not ‘revolutionary’ at all. Moreover, you’d need to scan the patient’s limb – we are all different. Then there is time. A hospital will have this done in ten minutes, so how long before this comes out of the printer? Another thing is that you have to clean up a 3D print, or it has rough edges left on it – rather you than me! Then ether is the cost. Are they trying to tell us that this much 3D print filament costs less than plaster?
According to Dr Jeffers and Renishaw, which is one of the world’s leading engineering and scientific technology companies, with expertise in precision measurement and healthcare, the partnership between Imperial College London and Renishaw is creating really exciting data on new materials that can control the way bone repairs itself these materials could change the way orthopaedic implants are designed in the future, and certainly provide an opportunity to improve patient outcomes by repairing the musculoskeletal system with materials that can invoke the desired response in bone.
On display at the show will be a portfolio of additive manufacturing builds to showcase what can be achieved on the Renishaw platform with Beta type capability. The builds include lattice structures which are more complex, in terms of resolution and density, than anything that can usually be achieved using traditional manufacturing techniques”.

Artificial placenta created in the laboratory

Posted on Updated on

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.”
