3d-nanoprinting speed record set by vienna university

New world record of fastest 3D speed-printed nano-
Researchers in Austria claim to own the items.
The team was able to create sculptures that were small to a grain of sand in a fraction of the time it took before.
To demonstrate the process, the team created a model of f1 racing 0. 285mm (0. 011in)
More than 4 minutes.
Scientists say the technology can be used to make small biomedical parts.
In order to produce the car, the equipment of the Vienna University of Technology has created about 100 layers, each of which consists of 200 printing lines.
\"The technology itself is well known in the scientific community, but the problem is that it is always very slow,\" Professor Jurgen Stampfl told the BBC . \".
\"It\'s a great show, but it\'s too long for real-world apps --consuming.
It takes hours or even days to make complex large 3D structures. \"Using our set-
And materials, we can increase the speed by 500 times, or in some cases by 1,000 times.
\"The formal name of the process is\" two-
Photon exposure \".
It involves focusing the laser on the liquid resin to harden it, leaving a solid polymer line that is several nanometers wide.
Different from traditional 3D
By adding layers to the surface of the object to construct the printing technology of the object, the laser can create solid materials anywhere in the liquid material.
This process gets its name because the resin is only set when the molecules inside the resin absorb both light from the beam at the same time --
It only happens at the center of the beam.
The team\'s breakthroughs included improving the control mechanism of the mirrors used to focus the laser and developing special resins involved in the process.
Researchers are now developing creatures.
Compatible resin so that the objects they create can be used by doctors.
One suggested application is to create a scaffold that cells can use to build new biological tissues.
Engineers at Washington State University have shown 3D-
The printer can be used to make the stand to promote the regeneration of the damaged bone.
Professor Stampfl says his team\'s technology can work in the water
Based on the environment, this means that it is also able to create a scaffold suitable for more soft tissues such as cartilage and muscle tissue.
\"When we use infrared lasers that are completely harmless to biological tissues, we can also\" write \"these structures in the presence of cells,\" he added . \".
\"This is impossible for other 3D --
Printing technology, which relies first on the manufacture of a scaffold, then seeding the cells, or using a thin inkjet nozzle to pass through the cells that may damage the cells. \"The two-
Photon exposure technology allows us to write in the same space as cells.
What we said-vivo writing.
