The event

Concrete is already used in many ways as a stylistic element in architecture. If you want to go even further, you can combine concrete with other technologies. Light fixtures, advertising spaces and screens, charging connections and other technology combinations put objects in the spotlight in the modern and smart world. 3D concrete technology creates forms of the future and combines them with technologies of the present. This is the only way to create the functional free-form concepts for modern furniture design as well as durable and timeless urban designs. 

There are no limits to the imagination. Almost all shapes and sizes are feasible. This opens up completely new and individual possibilities for designers, planners and architects as well as for their customers. In the case of a high degree of complexity or if elements are assembled manually, a 3D model can be printed in several individual parts. The object is reassembled in the factory or on site, depending on the requirements.

For design objects, furniture, object covers or wall coverings, pure 3D concrete print objects are usually created. This means that the entire component is created robotically using the 3D concrete printing process. Size and complexity determine the print mode of an object. Which printing mode makes sense and can be used for printing depends on the object and is decided by the 3D concrete technology experts at uniQum.

The production is done by creating a so-called "lost formwork". The 3D concrete printer creates the outer silhouette of the concrete part. This silhouette is the formwork and is later filled with concrete. Before that, a reinforcement cage is created and inserted into the 3D concrete silhouette. The reinforcement cage is made of structural steel or carbon fabric. The concrete formwork already acts as a concrete cover to prevent carbonation (in the case of steel reinforcements). The type of reinforcement used depends on the area of application, shape and static specifications. With this type of production, partial elements can also be created and cast together in the second work step.

Colour printing with concrete is also possible. This is made possible by 4FP colour printing using special liquid pigments for 3D concrete. The designs of the concrete furniture are individually adapted to the desired appearance by the planners and designers.
