Detailed explanation-1: -Which country has developed ‘GRX-810’, a 3D printed superalloy? Explanation: The USA has developed ‘GRX-810’, a 3D printed superalloy.

Detailed explanation-2: -The 3D Print Canal House was a construction project. The first residential building in Europe and the CIS, constructed using the 3D printing construction technology, was the home in Yaroslavl (Russia) with the area of 298.5 sq. meters. The walls of the building were printed by the company SPECAVIA in December 2015.

Detailed explanation-3: -The world’s first 3D printed car or ‘Strati’ was the product of a design contest and was created entirely using direct digital manufacturing. The 49 parts that make up the Strati took 44 hours to print.

Detailed explanation-4: -GRX-810 is made primarily of nickel, cobalt, and chrome, but it is laced with nanoscale particles of a ceramic oxide called yttrium, yielding an “oxide-dispersion-strengthened” (ODS) alloy. It’s long been known that incorporating such materials into metal alloys can enhance their strength, ductility, and hardness.
