The 90 to 200m 2 3D printed homes take around five to seven days to print, compared to a timber frame which would take up to 16 weeks in the same area. [22] ICON also completed a project in March 2020 for seven 3D-printed homes in Austin, Texas. Each 400 ft 2 home was printed in just 27 hours using ICON's Vulcan printer. The first residents ...
By January 2013, working versions of 3D-printing building technology were printing 2 metres (6 ft 7 in) of building material per hour, with a follow-on generation of printers proposed to be capable of 3.5 metres (11 ft) per hour, sufficient to complete a building in a week. [81]
Icon's 3D printer system constructed the walls of the over 2,000-square-foot home and its ADU in eight days despite weather and hardware issues. Icon's 3D printer system constructed the walls of ...
The system was announced in 2017 [26] and launched in 2018, consisting of the Metal X printer, Wash-1 debinding station, and Sinter-1 furnace. The Metal X printer has a build volume of 300mm x 220mm x 180mm. Available materials on the Metal X system include 17-4PH stainless steel, tool steels (H13, A2, D2), Inconel 625, and pure Copper.

3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
The tieback-deadman structure resists forces that would otherwise cause the wall to lean, as for example, when a seawall is pushed seaward by water trapped on the landward side after a heavy rain. Tiebacks are drilled into soil using a small diameter shaft, and usually installed at an angle of 15 to 45 degrees.
RepRap (a contraction of replicating rapid prototyper) is a project to develop low-cost 3D printers that can print most of their own components. As open designs , all of the designs produced by the project are released under a free software license , the GNU General Public License .
