Earth magic of 3D printing to dry "God" event!

3D printing technology on Earth, will help mankind to plant on the ground to move in space? This is not sensational. Domestic 3D printing and aerospace scientists recently announced that, as a disruptive manufacturing technology, 3D printing will bring significant changes in the field of aerospace.

The magic of 3D printing, aerospace bring what to give? It had to start from the principle features of 3D printing technology.

Principle: Two-dimensional "slice" of the three-dimensional object heap

3D printing technology was born in the 1980s in the United States, the object is three-dimensional structure design, hierarchical processing, forming a superimposed manner to a laser beam or an electron beam as a heat source, the plastic, metal alloys, ceramics and other materials powder graphics layer by layer according to the pre-designed high-temperature melting, solidification, and finally fully consistent with the three-dimensional model of the part real part, also called "increasing material manufacturing."

If the die casting technology as frozen popsicles in the freezer, like a blacksmith forging technology is tempered blacksmith, so 3D printing is a new overall manufacturing technology.

Imagine aircraft turbine disc, box beams, aerospace engine pump casing, spacecraft capsule mesh panels and other components from the 3D model to cut several layers of two-dimensional "slice", just two print layer by layer dimensional "slice" is superimposed and bonded, you can quickly complete the product to make it.
