A Chinese construction company has unveiled its two largest 3D-printed buildings to date. One is a grand-looking, 3-story mansion, and the other is a more utilitarian 5-story apartment block.
Both are made entirely by 3D printers creating layers of materials that form walls and roofs. Here is the 5-story apartment block.
The parts were fabricated using a diagonal reinforced print pattern
A specially formulated ink made up of concrete, fiberglass, sand and a hardening agent was used in the creation. This special ink is flexible, self-insulating and is resistant to strong earthquakes.
This efficient construction method saves 60% of the materials
The method also saves 70% of the time and 80% of the labour needed when compared to building a traditional home
The apartment and the mention are a proof-of-concept for now. Currently, they are positioned side-by-side in an expo area.
This partially finished wall section shows how the giant 3D printer creates layers of 3D-printed concrete that is later formed into a section of wall. These pre-fabricated elements are then put into place to build the entire structure. The company's name is Winsun.
