China3D printingNet January 28th, recently, Boeing 777X made its first flight. This is3D printingAt an important moment in history, each of the two GE9X engines driving the aircraft has about 3003D printingComponents, these components are manufactured by the GE Additive Technology Center in Ohio and the team of Avio Aero, Italy. The incident was so important that Boeing was tracking the flight that day.
The Boeing 777X is an upgraded version of the Boeing 777 launched in 1994. Its carbon fiber and folding wingtips can be instantly identified.As fuel usage and emissions have been reduced by 10%,777XIt is recognized as the largest and most fuel-efficient twin-engine jet aircraft on the planet.Considering the huge carbon emissions of the aerospace industry, and777X can effectively controlcarbon emission.
Part of the reduction in emissions is due to the new aerodynamic design and GE9X engine. The GE9X is as wide as the Boeing 737 and is the world’s largest engine on any commercial aircraft. This size is achieved through the use of advanced fiber composite materials, which reduces the number of blades in the system from 22 in GE90 to 16.In addition, GE9X also uses the now famous3D printingFuel nozzle, reducing the number of parts from 20 to one.

Other features, such as the use of lightweight and heat-resistant ceramic composites on the engine cover, can not only increase weight and save fuel, but also make the GE9X the most powerful engine on any commercial aircraft. It can provide up to 100,000 pounds of thrust.
After GE9X conducted a test flight in March 2018, they have been installed on the 777x. The aircraft was originally scheduled to take off on Saturday, January 25, but was delayed due to weather. On January 26, the plane took off and landed from the Boeing Airport outside Seattle.
Boeing 777X in size, performance and3D printingThe number of parts is competing with Airbus A350 XWB. A350 already has more than 1,0003D printingParts, including cabin parts manufactured using Stratasys technology, titanium alloy pylon brackets and 3D cabin spacers printed by Materialise. What it does not have is the recent history of catastrophic engine failures related to the 737 MAX engine.
Although we may not have forgotten the tragedy related to the 737 MAX, the company will have to do more work to obtain FAA certification to reassure its customers and the public. Of course, the FAA stated that it will ensure that the aircraft is strictly reviewed after ignoring the 737 Max, and Boeing also stated that it will conduct a comprehensive test to obtain FAA certification. Emirates, the aircraft’s launch customer, has stated that it hopes to be more rigorous in the testing process.
777X is expected to be put into use in 2021, one year later than the original plan. On the other hand, the A350 has already started flying.
