4D printing technology can change the shape of printed objects

Researchers at the Massachusetts Institute of Technology have used 4D printing technology to create objects that can change shape. MIT mathematician is also the principal person in charge of the research Danaviev and his colleagues are studying 4D printing, which involves shaping the shape of the 3D printing project. The researchers used two materials with different properties for 3D printing. One type of material is hard plastic and is fixed in shape after printing, while the other material is water-absorbing and may double when immersed in water.
This water-absorbing material, developed by the 3D printing company Stratasys in Minnesota, has not been disclosed. In this study, the researchers printed a square grid measuring approximately 15 inches or 38 centimeters on each side. When they placed the grid in water, they found that the absorbent material began to stretch. The researchers used 3D printing to create a shape similar to the English abbreviation MIT and transform it into another SAL-like English abbreviation. Researchers said: "In the future, the technology will be widely used."

AMRTA series air cooled water chillers and heat pumps are designed for outdoor installation and generally for both commercial and industrial application with the ability of 24 hours/day operation. The units are factory tested and on site installation will be completed only by connecting with the water kit components and power supply.
