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
Future proof solution for concrete 3D printing
Although in its infancy, 3D Concrete printing is giving 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 which all have an impact on the performance of the material.
Essentials for assessment of 3D printed structures
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 that 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.
