3D Concrete Printing

Working without concrete forms, the calculation of the exact mix and speed of the print is essential. DIANA can help you predict the behavior of the flow, and ultimately the behavior of the structure.

Pioneering the next generation of concrete technology 

3D concrete printing gives structural designers a new creative opportunity to design intricate decorative features and innovative designs of larger structures such as small bridges or houses. Concrete technology is leaping forward, with fiber reinforcement and ultra-high-performance fiber reinforcement becoming more widely used, along with a range of other concrete additives, all of which impact the material’s performance. DIANA provides a future-proof solution for concrete 3D printing, enabling designers to explore new possibilities and push the boundaries of what is achievable in construction.

Stability assessment of concrete printed structures

Whilst this new technology should result in structures being built in a fraction of the time, and fraction of the cost – it should not be a case of trial and error. In conjunction with major concrete manufacturers, DIANA provides you with the ability to predict the performance of the concrete as it is poured, including a range of analyses.

Not forgetting that the way these structures are constructed is new to the market, there also needs to be different types of analysis carried out to ensure that it will stand up to the test of time, how will the joints react to heat, cold, and movement. DIANA has been at the forefront of this technology, working with research institutions to ensure that the right analysis features are available to DIANA users.

Special features for 3D Concrete Printing
