Video: 3D printer prints at home entirely

Big Delta is a giant 3D printer big enough to print a building. According to WASP, the Italian company that assembled it, it is the largest 3D printer in the world, and is intended for the construction of houses in developing countries.
WASP makes smaller printers, essentially the same design. They look like small boxes with three arms that work up and down in three directions. By moving the arms to different heights, the print head, which is attached to all three arms, can also move horizontally.
The head itself is the extruder from which the material comes out. Once the printer is set in motion, it creates a ceramic structure using a continuously flowing volume of material.
Big Delta works the same way, only its structure is an open matrix of steel trusses. It looks like a cross between a street festival scene and the skeleton of a gas meter. The hexagonal structure allows the oversized printhead to work anywhere inside.
The video below demonstrates a scaled-down version of the same giant printer at work.
The idea is to be able to place the superstructure anywhere, and fill the refueling cartridge with materials from local sources, such as clay. Then the printer prints the entire residential building, without the need for human labor, except for refueling the cartridge with material.
Big Delta was showcased at a three-day event in Massa Lombarda, Italy. “We have shown that this is not just a dream - low cost housing is possible - and that homes can be 3D printed,” said WASP creator Massimo Moretti.
The sale of small 3D printers brings the company about $ 2.2 million a year, this money, they claim, is invested exclusively in research.
Low cost and high quality housing is just the beginning. WASP is working with another Italian company, Health R&S, to 3D print buildings with insect repellent walls. The project, says Giorgio Noera of Health R&S, "is not far from completion and will be critical in areas where populations have to constantly fight infections in order to survive."
