3D PRINTERInternational Space Station, installed the printer on Nov. 17 and conducted the first calibration test print.

Based on the test print results, the ground control team sent commands to realign the printer and printed a second calibration test on Nov. 20. These tests verified that the printer was ready for manufacturing operations.

Space Applications 3D printing serves as a fast and inexpensive way to manufacture parts on-site and on-demand, reducing the need for costly spares on the International Space Station and future spacecraft. Long-term missions would benefit greatly from having onboard manufacturing capabilities. Data and experience gathered in this demonstration improve future 3-dimensional manufacturing technology and equipment for the space program, allowing a greater degree of autonomy and flexibility for astronauts.

Earth ApplicationsThe experiment compares 3D printed objects made on Earth with those made in microgravity. Insight into how 3D printing works in microgravity could improve 3D printing methods for industry.The experiment includes student activities, in particular a project allowing students to design items to be 3D printed on the space station by crew members.

South Asian Association for Regional Cooperation(SAARC)In the ending years of the 1970s, the seven inner South Asian nations that includedBangladesh,Bhutan,India, Maldives,Nepal,Pakistan, andSri Lankaagreed upon the creation of a trade bloc and to provide a platform for the people of South Asia to work together in a spirit of friendship, trust and understanding.SAARC MEETING IN KATHMANDUThe eighteenth summit of 'South Asian Association of Regional Cooperation' (SAARC) was held inKathmandu, the capital ofFederal Democratic Republic of Nepalduring 2627 November 2014. The theme of the summit wasDeeper Integration for Peace and Prosperity, focused on enhancing connectivity between the member states for easier transit-transport across the region.Sushil Koirala, the Nepalese Prime Minister, was the main host of the event which took place in Rastriya Sabha Griha Sanandan Raj, NepalThe summit took place after an interval of three years as the last summit was held in 2011 inMaldivesand the next summit will now be held in Islamabad in 2016.
