New 3D printing technology to print multiple alloys in a single object

3D printing and 3D printers have seen a lot of development lately, they have been used to create a lot of things ranging from gadgets and accessories to bio-medical implants and prosthesis equipment. 3D printed metal alloys and compounds have been long been fabricated, however no major breakthrough has yet been made on 3D printed spacecraft’s or jet crafts, for that matter.

A lot of research has been going on, on this and recently scientists and researcher’s at NASA’s jet Propulsion Laboratory in Pasadena, California have come forward with a revolutionary new 3D printing technology that can 3D print more than one metal alloy in a single 3D printed object.

Why would you need to make such an Object?

Let’s imagine a thermostat, it is made up of two metals joined or welded together, the difference in how the two metals react to temperature, causes the device to react differently to different temperatures. This helps us in deploying this device as a safety cut-off measure, in the case of over-heating or vice – versa. However, imagine if there is a defect in the weld or it is too brittle, would you still trust that device with over-heating problems? No – definitely not.

This is exactly why such a technology is needed, he fact that it came alive with 3D printing technology, is just another feather on the hat.

How does it work?

We’re taking a standard 3D printing process and combining the ability to change the metal powder that the part is being built with on the fly,” said Douglas Hofmann, a researcher in material science and metallurgy at JPL, and visiting associate at Caltech. “You can constantly be changing the composition of the material.

Rather than adding layers from the bottom, as in the other 3D printing technology, Hofmann and his colleagues are depositing layers of metal on a rotating rod, thus transitioning metals from the inside out. They are using a laser deposition (LD) technique to fabricate multifunctional metal alloys. Using the technique in parallel with rotational deposition enables fabrication of compositional gradients radially from the center, thereby altering the mechanical and physical properties of the alloy.

The research work was funded by NASA, further details on this revolutionary new 3D printing technique can be found here.

 

TI Cycles makes first 3D printed light weight titanium bike

US Army to use 3D printing to create ballistic warheads

The U.S. Army plans to use 3D printing to print warheads that could not only save the military cash, but also expand its capability of making simpler weapons, per the newest issue of Army Technology. 3D printers will manufacture gold shapes that are not possible or much dearer to supply on traditional machine tools. And also the limitless potential of the shapes created by additive producing evokes style engineers within the Army.

Warhead designers plan to produce blast effects that meet specific criteria, explained James Zunino, a man of science at the Armament analysis, Engineering, and style Center. They will need blast fragments of specific sizes to radiate in specific directions such their blasts will most effectively destroy desired targets.

Warheads can be designed to satisfy specific mission necessities whether or not it’s to enhance safety or to satisfy Insensitive Ammunition demand, or it may have tailor able effects, higher management, and be ascendible to attain desired morbidness,” James Zunino, a man of science at the Armament analysis, Engineering, and style Center wrote to Motherboard.

The limits on what will be created by using machine tools limit load shapes. By lifting limitations through the swollen capabilities that escort additive producing, the house is can expel a lot of expeditiousness.

Once you get into detonation physics you open up a full new universe,” Zunino aforementioned. “The real worth you get is you’ll be able to get a lot of safety, morbidness or operational capability from an equivalent house,” Zunino aforementioned.

In addition, 3D printing conjointly helps the military saving cash on obtaining components or tools delivered to a forward-deployed soldier. If you add up all the price, as well as the transportation prices, fuel, security, it’ll be less expensive to simply print them out.

3D printing conjointly permits for integration parts along to feature capabilities at reduced total life cycle prices,” Zunino explained. “It is anticipated that 3D printing can scale back life-cycle prices of sure things and create munitions more cost-effective within the end of the day through implementation of style for manufacturability, and capitalizing on the add capabilities that 3D printing and additive producing will bring back munitions and warheads.

Eventually, the military needs to print the entire factor in one print job. “Maybe sometime a complete load or rocket can be created because the technology any matures,” Zunino wrote.

NASA releases 3D models for 3D printing fans

More than a dozen NASA satellites and space vehicle perpetually monitor our planet’s very important signs. So, as to urge individuals inquisitive about our galaxy and permit those with access to a 3D printer to supply their own version of space vehicle, NASA has recently released twenty one such 3D models of asteroids, NASA’s space vehicle and satellite, and planetary surfaces etc, on their web site.

These .stl-formatted 3D printable models are scaled to four inches (100 mm) within the longest dimension and they are offered for transfer at no cost, to help make it simple for users, NASA has even pre-cut the big items to make them 3D printable.

However, NASA is aware that 3D printing usually involves trial and error therefore in all probability not each model is 3D printable. NASA states on every page that “the .stl file was made by scaling the initial model and changing it on to .stl format; it should not nonetheless be ideal for 3D printing, we tend to welcome your feedback on your expertise.

On NASA’s web site, you’ll realize a growing assortment of 3D models, textures, and pictures from within NASA. All of those resources are absolve to transfer and use. “Our team’s goal is to produce a one-stop solution for 3D models, images, textures, and visualizations.

We may soon have 3D cell printed tissues

Tissue engineering and tube biology expert Guohao Dai, professor within the Department of medical specialty engineering at Rensselaer polytechnic, has won a Career Development Award (CAREER) from the National Science Foundation (NSF) for his analysis into bio-fabricating human tissues with 3D cell printing.

Adult neural stem cells are celebrated to carry an excellent potential for treating illness and harm to the systema nervosum. However, these cells are rare and tough to breed during a laboratory setting, as a result the cells lose their efficiency quickly upon being far away from their native setting. Dai can use the five-year, $440,000 grant to style and develop a replacement approach using 3D cell printing technology to make a “vascular niche” that replicates the native setting of adult neural stem cells.

Unlike the cells within the body, a significant challenge in making and learning 3D tissues is the diffusion limit within the tissues, which quickly lose efficiency or die while not on a flow of blood to supply gas and nutrients. To help overcome this challenge, Dai and his team have spent years developing a 3D tissue printer that prints biological tissue by rigorously depositing cells, hydrogels, and alternative materials one layer at a time. Using this platform, Dai developed the technology to make perfused tube channels, which offer nutrients and gas to the 3D cell printed tissues.

Blood vessels run throughout virtually each a part of our body, transferring the gas and nutrients that enables our cells to survive. Constant is not true of 3D cell cultures they have a system so as to survive,” Dai said. “Our device will print 3D tissues with tiny channels that perform as blood vessels this allows to print cells with animated matrices that closely replicate those found at intervals in the body.”

If productive, the project might considerably expand the efficiency and life of the cells in laboratory settings, and cause a more robust understanding of however this animate thing influences the behavior of the cells.
