Scientists take "4D printing" a step further

Scientists take "4D printing" a step further | 3D and 4D Printing | Scoop.it

Using a 3D printer, people can already determine the length, width and depth of an object that they create. Thanks to research being conducted at the University of Colorado, Boulder, however, a fourth dimension can now be included – time. And no, we're not talking about how long it takes to 3D-print an item. Instead, it's now possible to print objects that change their shape at a given time.

 

The scientists, led by Prof. H. Jerry Qi, have developed a "4D printing" process in which shape-memory polymer fibers are deposited in key areas of a composite material item as it's being printed. By carefully controlling factors such as the location and orientation of the fibers, those areas of the item will fold, stretch, curl or twist in a predictable fashion when exposed to a stimulus such as water, heat or mechanical pressure.

 

The concept was proposed earlier this year by MIT's Skylar Tibbits, who used his own 4D printing process to create a variety of small self-assembling objects. "We advanced this concept by creating composite materials that can morph into several different, complicated shapes based on a different physical mechanism,” said Martin L. Dunn of the Singapore University of Technology and Design, who collaborated with Qi on the latest research.

 

This means that one 4D-printed object could change shape in different ways, depending on the type of stimulus to which it was exposed. That functionality could make it possible (for example) to print a photovoltaic panel in a flat shape, expose it to water to cause it to fold up for shipping, and then expose it to heat to make it fold out to yet another shape that's optimal for catching sunlight.

Wow! Interested to see what the next step will be in 3D printing!

This 4D printing is reminding me of Star Trek's replicator...is food next?

Sugar, chocolate 3D printing machines debut at US consumer show

Sugar, chocolate 3D printing machines debut at US consumer show | 3D and 4D Printing | Scoop.it

 

A husband and wife team has created a confectionery 3D printer that has debuted at the Consumer Electronics Show in Las Vegas.

 

The BBC and others report that The Sugar Lab’s ChefJet 3D printers are able to create intricate shapes out of both sugar and chocolate.

 

The Sugar Lab was founded by a Los Angeles husband and wife team, Liz and Kyle van Hasseln, who came up with the idea while studying as graduate architectural design students.

"We tried sugar," Kyle told The Atlantic.

 

"just because it was cheap—and then we realized that if we modified it, we could eat it."

 

The ChefJet and ChefJet Pro machines use a water and alcohol mix to moisten sugar (or chocolate) into a solution that is then extruded into a set design.

 

The machines start at over $US4,000 for a black and white model.

 

“We definitely think 3D printed sugar could catch on more widely, and we're excited about the potential of the concept being available to a wide audience,” Liz told The Daily Mail in an article published last year.

I really wish I was at the CES how this year in Vegas.  So many awesome innovations with a large showing from 3D Printing.  Food is another consumer related 3D Printing field that is just coming to the forefront.

How 3D Printing Supercharges Nike’s New NFL Shoe Designs

How 3D Printing Supercharges Nike’s New NFL Shoe Designs | 3D and 4D Printing | Scoop.it

Almost a full year ago, Nike introduced its first shoe ever built with the help of 3D printing technology.

 

The thing was, that cleat, the Vapor Laser Talon (seen below), was built for an absurdly specific purpose and market—just the 40 yard dash, just for NFL players.

 

Now, though, Nike is bringing what it's learned from the VLT to the consumer market—innovations that, without 3D printing, we might not have seen for years to come.
