3D printing

3D printing is an innovative technology that uses material placement software to create a 3D object or structure without the need for standard formwork. The most common paving process is based on the extrusion of cement-based composites, be it fine-aggregate mortar or coarse-aggregate concrete. 3D printing makes it possible to produce products of complex geometry on a fully automated plant. Printing is possible with a robotic arm, which is more suitable for "experienced" operators (usually robot suppliers themselves) to print individual elements with high complexity and detail, and a portal 3D printer - ideal for printing much larger structures, for example, entire buildings.

Key advantages of the technology:

how to save materials,
increasing the efficiency of production of complex concrete products,
new architectural ideas and design strategies.

3D construction process

Construction speed depends on many factors: building size, material properties, worker experience, and other project management factors. Small buildings less than 50 m2 can be built in one day. It is possible to build high-rise structures and multi-storey buildings.

It usually takes 4 hours to set up a 3D printer. Curing time is highly dependent on weather conditions and the composition of your mix and can take anywhere from 1 to 20 minutes or more. At the same time, as a rule, there are no strict requirements for the use of materials for the building mix - it can vary greatly depending on local conditions.

The construction process using a 3D printer can vary, but for example, when building a standard building, it will consist of:

Site preparation
Printer settings
Foundation Outline Prints
Wall prints on the first floor
Decks settings
Repeat procedure for multi-storey buildings
House closings (roof, windows, doors)
Finishes (paint, floors, electricity, HVAC).

Terraforming Market is a service for selecting innovative solutions and technologies for sustainable urban development from well-known brands, research institutes and startups from around the world. Terraforming Market is designed to help state and municipal employees, architects and developers, as well as active citizens to find a modern and environmentally friendly approach to the development of the territory and the creation of the city.

The project is implemented by the Institute of Environmental Conservation and Ecosystem Development Technologies.
We study and summarize the experience of leaders in the field of nature conservation and ecosystem development in the era of the Anthropocene and disseminate best practices.
