Melt the sand with 1600 c of sunlight, making a bowl just to eat earth!

The sand in the desert will be roasted by the sun? It sounds like the sun is coming out of the west.
but the sand that is smoking tells you that it's true.
put the lens on a filter, we can see that the sand seems to be experiencing a volcanic eruption, melting a little bit into magma.
sunlight paints the seven stars of Beidou on the surface of the sand.
was stunned by the moment the sand was cut out after it was finished, and a real sand sculpture was removed from it.
the 3D printer, named Solar Sinter, Chinese "solar sintering machine."
developer was German designer Marcus Kaiser, who at first went to the desert to play ball, cutting and carving pieces of paper with crystal balls.
he later processed these pieces of paper into sunglasses, did not expect to be the fashion industry's pursuit.
the road to carving was out of control, and he began his own 3D printing in the Moroccan desert.
first need to lay the sand in the sand box, sunglasses are necessary, or will be reflected by the sand flash blind.
is responsible for heating the sand is the top Ofiel lens, short focal length, small size, light transmission performance, the sun focuses up to 1600 degrees Celsius of the beam.
and the photosensor can track the sun at all times, and the machine rotates the angle on the base to maximize the solar energy generated by the Fresnel lens.
driven by solar energy, the mechanical shaft controls the pattern of the sandbox on the X-axis and the Y-axis.
after each layer of sand pattern is printed, a new layer of sand is covered on the surface, cycling back and forth, printing the three-dimensional structure on the Z-axis.
the sand is melted and fully cooled and converted into glass, a powdered substance that eventually converts it into a solid, known as "sintering".
this series of operations is done by the computer, only the 3D modeling data needs to be copied to the computer, the program can automatically implement a variety of shapes of printing, such as this spiral sand bowl.
in 1933 in the Journal of Modern Machinery, scientists at the time came up with a vision of focusing sunlight with a lens and using solar energy to burn a road in the desert, and 78 years later, the idea finally came true.
it seems that the sand grain, this "slag" substance, will have great prospects.
