In this article, the author describes the work of Enrico Dini, who has developed a 3D printer able to print house-sized objects:<\/p>\n\n\n\n

3D Printing A Whole Building<\/a><\/p>\n\n\n\n

In Pisa, Italy, Enrico Dini has developed a machine called D-Shape which sprays a magnesium-based glue onto a thin layer of sand (at a resolution of about 25 dpi) to bind it into solid rock, which can be built up, layer over layer in a process that can include internal curves, ducting and partitions.<\/p><\/blockquote>\n\n\n\n

The following video is in Italian, but the images show you how the machine works. You have a big pile of sand and a spray arm that dispenses the glue that binds the sand together. After spraying a layer, more sand is added to the pile, it is leveled, and then sprayed again. You can jump forward 1 minute to see the machine and some of its output:<\/p>\n\n\n\n
