3D-printed lattice for bone repair
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
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.”

4D printing Programmable Textiles
According to the comments from the videos, ” 4D printing Programmable Textiles looks like, Lays potato chips are made. Once they’re produced on 3D printers, objects made of programmable materials continue to take shape, folding, unfolding or assembling themselves in response to outside stimuli such as light, movement, heat, pressure or water.
The programmable Materials consist of material compositions that are designed to become highly dynamic in form and function, yet they are as cost-effective as traditional materials, easily fabricated and capable of flat-pack shipping and self-assembly. These new materials include self-transforming carbon fiber, printed wood grain, custom textile composites and other rubbers/plastics, which offer unprecedented capabilities including programmable actuation, sensing and self-transformation, from a simple material”. 🙂
