The agency NASA has asked public to submit designs for a Mars habitat. NASA, along the National Additive Manufacturing Innovation Institute, is holding a competition to design and build a 3-D printed habitat for deep space explorations like journey to Mars.  The multi-phase 3-D Printed Habitat Challenge has been specifically designed to advance the additive construction technology that is needed to develop sustainable housing solutions for earth and beyond.  As per experts, is among most basic and crucial requirement for humans but carrying bulks of material to build up a habitat during a deep space would unnecessarily take the place in cargo that could be used for something important.  The first phase of the competition that was announced on Saturday will run through September 27. This phase calls on participants to develop state-of-the- architectural that take advantage of the unique capabilities 3-D printing .  The top 30 submissions will be considered and judged. Also winners will be awarded with prize money of $50,000 at the 2015 World Maker Faire in New .  Sam Ortega, Centennial Challenges manager, said, “This challenge definitely raises the bar from what we are currently capable of, and we are excited to see what the maker community does with it”… 

The space agency NASA has asked public to submit designs for a Mars habitat. NASA, along with the National Additive Manufacturing Innovation Institute, is holding a competition to design and build a 3-D printed habitat for deep space explorations like journey to Mars.
The multi-phase 3-D Printed Habitat Challenge has been specifically designed to advance the additive construction technology that is needed to develop sustainable housing solutions for earth and beyond.
As per experts, shelter is among most basic and crucial requirement for humans but carrying bulks of material to build up a habitat during a deep space mission would unnecessarily take the place in cargo that could be used for something important.

The first phase of the competition that was announced on Saturday will run through September 27. This phase calls on participants to develop state-of-the-art architectural concepts that take advantage of the unique capabilities 3-D printing offers.
The top 30 submissions will be considered and judged. Also winners will be awarded with prize money of $50,000 at the 2015 World Maker Faire in New York.
Sam Ortega, Centennial Challenges program manager, said, “This challenge definitely raises the bar from what we are currently capable of, and we are excited to see what the maker community does with it”.
Furthermore the second phase of the competition is divided into two levels i.e., the ( 1) Structural Member Competition and the On- Habitat Competition (Level 2).
The Level 1 focuses on the fabrication technologies that are needed to manufacture structural components from a combination of indigenous materials and recyclables, or indigenous materials alone.
On the other hand, the Level 2 challenges competitors to construct full-scale habitats using indigenous materials or indigenous materials combined with recyclables.
