Braskem takes technology to the International Space Station

Various types of parts using sugar cane-based 'I’m green' plastic to be located on NASA ISS

Green plastic producer Braskem has announced that, as a result of its partnership with U.S.-based Made In Space, the leading developer of zero gravity 3D printers and an official supplier to NASA, its bio-polyethylene is now also being used in space for 3D printing spare parts and tools.

wimage-1The first part made from the raw material outside of Earth was a pipe connector for a vegetable irrigation system, which was fabricated by the Additive Manufacturing Facility (AMF), the first commercial 3D printer permanently allocated in space. The equipment, which will fabricate various types of parts using sugar cane-based I’m green plastic, is located on the International Space Station (ISS) and was developed by Made In Space with the support of the Center for the Advancement of Science in Space (CASIS).

Over the past year, Braskem’s Innovation & Technology team has been working with Made In Space to develop a Green Plastic solution especially for 3D printing in zero gravity. The partnership will enable astronauts to receive by e-mail digital designs of the parts and then print them, which means dramatic savings in terms of time and costs.

“Through this partnership, we combined one of the greatest innovations in polymers, Green Plastic, with advanced space technology to print 3D objects in zero gravity. Putting a renewable polymer in space for printing applications represents an important milestone in our history,” said Patrick Teyssonneyre, director of Innovation & Technology at Braskem.

Polyethylene made from sugarcane was the material chosen for the project because of its combination of properties, such as flexibility, chemical resistance and recyclability, and also because it is made from a renewable resource. There are great expectations surrounding the project’s benefits, since 3D printing in space was defined by NASA as one of the advances essential for a future mission to Mars.

“The ability to print parts and tools in 3D on demand increases the reliability and safety of space missions. This partnership with Braskem is fundamental for diversifying the raw materials used by the AMF and for making this technology more robust and versatile,” said Andrew Rush, CEO of Made In Space.

The equipment’s printing bed is made of Braskem’s ultra-high molecular weight polyethylene (UHMW-PE), which is marketed under the brand UTEC. The resin provides increased tack for printing with Green Polyethylene and offers mechanical properties, such as superior abrasion and impact resistance.
