3D printers can print models and other small 3D objects, but a finished house? A British company has now made it possible.
The British firm D-Shape has allegedly built the world's largest 3D printer that can print objects the size of a house. 3D printers are already in limited use in industry to produce models of such. cars or buildings, and they are also used in the art world.
3D printers based on inkjet technology builds the finished object up layer by layer, where each layer has approximately the same thickness as a piece of paper. The printers use a special powder which is very expensive, but work on finding cheaper materials.
D-Shape has been dealing with another problem - namely how to get the printer to print larger objects.
The big machine consists of an aluminum frame of six times six meters (can be extended almost indefinitely) that resembles an ordinary building scaffolds. And it's not completely wrong. Printer head moves back and forth on a bridge, mounted on the tripod and running up and down, back and forth in the racks.
Head inside the team 300 servo nozzles that spray a combination of sand and a special bonding material out with a speed of 0-500 mm / sec.
First, the architect designing his object in an ordinary 3D CAD program on your computer, then file is converted to STL format (stereolithography) and imported into the program that controls D-Shape printer head. The process starts from scratch and build the object up layer by layer.
D-Shape says that it takes 24 hours before the material is firm and dry. The machine itself takes a few hours to assemble and disassemble. The entire facility weighs five tonnes and uses 40 kW during normal operation.
The British producer imagines that the machine can be used to print everything from benches, sofas and bridges for gravestones.
A presentation of the unusual 3D printer can be obtained from D-Shape. Apparently not what giant printer to cost.
