Berkeley’s 3D printer shot into area for 140 secs, prints toy shuttle

Guess what hitched a trip on Virgin Galactic’s newest mission? A high-tech 3D printer specifically designed for area purposes. 

For astronauts on distant missions, 3D printing might come to their rescue when spare components are working low. The method can merely fabricate and restore any very important spacecraft components that break removed from Earth.

UC Berkeley engineers have developed this superior 3D printer referred to as SpaceCAL to save lots of the day for astronauts on missions to the Moon and Mars. This microgravity 3D printer took its first suborbital area flight aboard the VSS Unity area aircraft on Virgin Galactic’s mission 07 in June. 

It spent a fast 140 seconds floating round and even autonomously printed some cool stuff, just like the area shuttle figurine, utilizing a particular liquid plastic. 

“SpaceCAL carried out effectively below microgravity situations in previous exams aboard parabolic flights, however it nonetheless had one thing to show,” mentioned Ph.D. scholar Taylor Waddell. 

He added: “We hope that sometime it might be used to fabricate every thing from components and instruments for spacecraft to new contact lenses and dental crowns for crew members.”

NASA supplied $1.4 million in grant funding and engineering assist for this venture. 

Employs new printing method

SpaceCal makes use of a brand new sort of additive manufacturing method referred to as Computed Axial Lithography (CAL). Berkeley group developed this 3D printing expertise in 2017 and has been actively working to validate its readiness for area journey.

This 3D printer is alleged to be tremendous quick and environment friendly, creating components in 20 seconds. The builders spotlight that this extraordinary velocity units it aside from different 3D printing applied sciences.

This 3D printing technique makes use of gentle to rapidly print complicated, stable shapes from a viscous liquid. This light-based method holds the potential to broaden the forms of 3D shapes printable in area. 

CAL’s skill to print components on demand may very well be a game-changer for lengthy area missions. It eliminates the necessity for astronauts to lug round hundreds of spare components, considerably lowering total weight.

“You’ll be able to cut back that upmass, make these missions go quicker, and cut back danger by bringing manufacturing applied sciences with you,” mentioned Waddell within the press launch.

Furthermore, the autonomous type might permit the astronauts to be much less frightened in regards to the 3D printing course of.

SpaceCal has 3D printed 60 supplies on Earth

On Earth, the 3D printer has been capable of fabricate over 60 totally different supplies, together with silicones, glass composites, and biomaterials. 

“So, with the cabin, in case your spacecraft is breaking down, you possibly can print O-rings or mechanical mounts and even instruments,” Waddell mentioned. “However CAL can be able to repairing the crew. We are able to print dental replacements, pores and skin grafts or lenses, or issues customized in emergency drugs for astronauts, which is essential in these missions, too.”

Apparently, Waddell and his group have discovered that this printer can produce sure components in microgravity with excessive effectivity as in comparison with Earth.

Constructing on their success, Waddell and his colleagues are teaming up with NASA to develop 3D-printed medical objects for area journey. This may very well be something from a dental crown to a wound closure machine, a major step ahead for astronaut well-being on lengthy missions.”

The longer term holds much more promise. The group envisions CAL printing complicated human organs. Due to a NASA grant, this thrilling risk shall be examined on the Worldwide House Station quickly.
