Concrete and black concrete 3D printing

One of Shahaf's goals is to elevate cement-based 3D construction printing (3DCP) from its theoretical phase to a whole new practical era of liberation from past inhibitors. We, at Shahaf, concentrate our experience, knowledge and expertise in order to take 3D printing to the next level.


Concrete printing can also be defined as a form of additive manufacturing used to construct buildings or any type of concrete construction, components in new and completely new shapes that were not previously possible with the traditional concrete form of work.


Black concrete has always been a challenge to many architectures and in the construction industry. Not many architecture or builders are successful in building using black concrete, but now, with the help of 3D printers, builders can now expect zero errors. The process injection of the black concreates using a 3D printer is fast and that the material combinations developed are inexpensive and economically well within the range of common building materials.

3D printing on a large scale?


While traditionally complex large objects or machines had to be molded, today's large scale 3D printing is becoming more and more available. Large scale 3D printing is cost-effective since there is no material wastage and less time is used to mold intricate concrete geometrics that usually requires multiple parts to assemble and shape.


3D printing key challenge


3D printing in construction is in the early stages of adoption, and furthermore, this tech offers promising future potential for the architecture and construction industry. Today one of the most popular for 3D printing in this industry is 3D precast formworks.

The term Formworks refers to a temporary mold where concrete is poured and formed. Formworks are used to create anything, including foundations and the walls of a building.

When the framework is produced manually using wood, it is not durable, but 3D printing can help provide a more substantial structure.


A key challenge of this technology is to print a top frame or surface that has a void below (like a roof). This problem forces the structure to use many printed "scaffoldings" to support the top frame, resulting in material and time waste. One way to tackle this problem is to form a plastic framework to hold the top surface. After concrete stables, the frame is easily removed.



Concrete 3D printed structure


3D printing of concrete is a promising technology that can save billions of dollars in the construction industry. When given enough time, 3D printing is the future of the architecture and construction industry. furthermore, this is a rapidly growing industry. 3D printing is estimated to be worth over $45.7 billion by 2025.


Shahaf Ltd. is leading the 3D printing revolution by researching and developing technologies and materials and by providing complex solutions to entrepreneurs, engineers, architects, designers and other professionals in the field.
