4D print self-transformation

3D Printing News Alert(Higher temperature responsive 4D printing)

Posted on Updated on

According to Chen X, Liu X, Ouyang M and Dr Connor Myant, a lecturer at the Dyson School of Design Engineering and Imperial College London (ICL),”explored 4D printing and its potential to herald new opportunities for industries and consumers.,”a novel electrochemical 3D printer with 2 deposition nozzles was presented which is capable of printing temperature responsive multi-metal (copper and nickel) 4D structures. An electrospun nanofibre nib was used to provide sufficient back pressure to the hydraulic head exerted by the electrolyte, replacing the porous sponge material used in prior works”.

4D printer could accelerate technology

Posted on Updated on

American Chemical Society is researching about 4D Printer. They have the ACS 255th National Meeting & Exposition in New Orleans.
4D printer could accelerate technology. Scientists report that they have developed a powerful new printer that could streamline the creation of self-assembling structures that can change shape after being exposed to heat and other stimuli.
American Chemical Society says this unique technology could accelerate the use of 4D printing in aerospace, medicine, and other industries.:)

NASA’s Meteorite resistant chain mail 4D Printed fabric.

NASA are stepping straight into the future of textiles with their 4D printed ‘space fabric’—a metallic material intended to be used like ‘chain mail’ to protect astronauts and spacecraft alike during their missions.The material remains fold-able and retains the ability to change shape easily.

4D print self-transformation can be more useful in future wearable technologies.:)

Dr. 4D printing (4D printing is copycat of mother nature)

Posted on Updated on

Mr.Jonathan Stickland, is our specialist in 4d print technology. We know some of the parts of 4D printing. 4D printing is emerging technology.

4d printing would be useful for car manufacturing.The structured technology of 4d printing is designed for repairing damage without command cars can be safer with less regular maintenance and servicing 4d printing can be used to ensure that the manufacturing process of cities can be built on time efficient schedules.

This will benefits our future medical technologies. 🙂

 

first 4D-printed water valve

Posted on Updated on

ACES researchers have turned their attention to the medical field of soft robotics, manufacturing a valve that actuates in response to its surrounding water’s temperature. ACES is the first group to combine printing a 4D device with four different cartridges simultaneously, while using tough gels with the incorporated actuating materials.

The fourth dimension is time, shape shifting in fact, and the ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong is helping to set the pace in the next revolution in additive manufacturing.

4D printed water valve will save our money

Mystery of 4D printer

Posted on Updated on

We always wonder it will be fun to buy 4D printer. But the 4D printers mystery is solved !!!!

Jenny is from BBC, she got in touch with the chief scientist, Professor Marc in het Panhuis.

What will be 4D printing future, where can we buy 4D printers, what technology are we using our product 4D printed. This is an advance technology.

For these questions, we need to go to this site.

Dr. 4D printer (4D printing Programmable Wood)

Posted on Updated on

Dr. 4D printer is informing us what is good and what is not good, 4D printing’s Programmable wood.

Meri asked about 4D printing wood, “is this 100% wood? concerns: are 3d and 4d printing materials biodegradable, earth-friendly, environmentally friendly and safe for people during use and production of items made by the 3d and 4d printing? I read at the University California Irvine facebook that student(s) are having to build something extra to help with the fume created during 3d printing. The fumes can be very bad for health as we inhale and surround ourselves in the fume during production and into the environment…air and so on…which then rains into the land, wildlife, river, and ocean contributing to global warming and destruction of the planet just to have accumulation of stuff…for joy and happiness of people. it could be like second hand smoking…what about other people in the planet and other animals and fish and the entire earth?? why should we all suffer needlessly for the joy of those who print excessively just to have stuff”.

For this comment. We still don’t have sufficient answer. 4D printing still in research stage.

I am sure in future we will use 4D printing more often.:)

4D printed’ material

Posted on Updated on

Lawrence Livermore National Laboratory, is in Livermore California.

Researchers from the laboratory, add hollow gas-filled “micro-balloons” into silicone-based ink, the researchers engineered the material so it can be compressed or “programmed” at an elevated temperature, remaining in that state as it cools. When reheated, the gas in the micro-balloons expands, causing the structures to return to their original shape. When combined with 3D printing, this shape memory behavior is often referred to as “4D printing,” with the fourth dimension being time.

“The impressive part was how well the structures could recover their shape after they were reheated,” said LLNL researcher Amanda Wu, the lead author. “We didn’t see a distorted structure, we saw a fully recovered structure. Because the silicone network is completely cross-linked, it holds the part together, so the structure recovers its original shape in a predictable, repeatable way.”

In the beginning, the process was an accelerated aging test to see if the material would be useful. 4D printing took on a pretty large compression set and that made them think if it was permanent. We weren’t really thrilled about that, but researchers tried to see if it could recover its shape when heated. They tested it and it was a successful experiment.
