3D printing for environment less waste, more sustainability

Posted on Updated on

According to Cartridge World, “3D printing also has the ability to create particularly fine details on its products, which could be useful in building artificial coral reefs to replace those lost by rising water temperatures and “inconsiderate tourist behaviour”. Previously, biologists have dropped concrete blocks into shallow waters in the hope of recreating reefs, yet studies have shown much marine life prefers surfaces with small holes and crevices to give protection from predators something 3D printing would be able to create”.

Lynn Rothschild has short brown hair and smiley eyes. She cracks jokes about biology and microscopes with ease. Diana Gentry, her decades-younger Ph.D. student, loves classic video games and vegetarian cooking. She lives near Silicon Valley. The two colleagues have a funny banter, and have spent holidays together. But they share one unique goal. They’re trying to 3D-print wood in space. Read More

3D Printer in Space
————————–
They use micro gravity. they are making keep sacks,it takes hour and hour and half to make an object.
“It’s not only the first part printed in space, it’s really the first object truly manufactured off planet Earth, Where there was not an object before, we essentially ‘teleported’ an object by sending the bits and having it made on the printer. It’s a big milestone, not only for NASA and Made In Space, but for humanity as a whole.”

“An astronaut might be installing it on the printer,” says Mr. Aaron Kemmer, he is the chief executive officer of Made In Space in Nasa.

“As we print more parts we’ll be able to learn whether some of the effects we are seeing are caused by microgravity or just part of the normal fine-tuning process for printing,” Werkheiser said in a NASA news release. “When we get the parts back on Earth, we’ll be able to do a more detailed analysis to find out how they compare to parts printed on Earth.” Niki Werkheiser,he is program manager in Nasa.
