The Egg Nebula (also known as RAFGL 2688 and CRL 2688) is a bipolar protoplanetary nebula approximately 3,000 light-years away from Earth.
Its peculiar properties were first described in 1975 using data from the 11 µm survey obtained with sounding rocket by Air Force Geophysical Laboratory (AFGL) in 1971 to 1974.
Pieces like the example in this photo were shown in the London Science Museum, UK, on Oct. 15 where international experts presented the world’s largest metal 3D-printing project, lead by ESA and the EU. AMAZE – Additive Manufacturing Aiming Towards Zero Waste and Efficient Production of High-Tech Metal Products – involves 28 industrial partners across Europe. 3D printing builds a solid object from a series of layers, each one printed on top of the last. This ‘additive manufacturing’ technique produces very complex structures with minimal waste and maximum flexibility.
