3D printed ceramics hold great promise in aerospace industry

Baba Health Tips

Researchers have come up with a new and original way to power 3D printing technology.

3D printing technology is the ability to create custom ceramics that are far more durable than these objects traditionally are. This ability to make crack-proof ceramics may even hint at some tantalizing potential in the aerospace industry.

Tobias Schaedler of Malibu-based HRL Laboratories said that “If you go very fast, about ten time’s speed of sound within the atmosphere, then any vehicle will heat up tremendously because vehicle will heat up tremendously because of air friction”.

People want to build hypersonic vehicles and you need ceramics for the whole shell of the vehicle. This could suggest the eventual arrival of hypersonic planes that could travel from one side of the globe to another in just a couple hours’ time.

According to HRL, the secret to its success in 3D-printing ceramics was the development of “pre-ceramic polymers” that convert to ceramic when heated in invention. This goes against the classical method of heating ceramic powder, which tends to result in a lot of tiny issues that ultimately manifest in the form of cracks, or even more severe forms of damage such as fracturing. That said, the process isn’t 100 percent perfect as of the moment, though close to it.

Schaedler further explained, “We have a pre-ceramic resin that you can print like a polymer, then you fire the polymer and it converts to a ceramic and there is some contraction involved, but it’s very uniform so you can predict it.”

HRL added that it may be probable to print out a very technical, highly-detailed ceramic part much faster than usual stereo lithography methods and try about 100 to 1,000 times faster than what is classically accepted. This would be due to the exploit of ultraviolet light and concentrated masks with patterns.
