Key features
Concrenetics’ 2K PRINTING UNIT packs all the components needed for 2K (or bicomponent) concrete printing at the end effector. It generally includes the latest generation of our in-house developed 2K inline mixing barrel, accelerator feeding system and other auxiliaries needed to transform a 1K print head to 2K.
The printing unit was optimized to be used with our own dedicated 3d-ink material formulation based on widely available raw materials and additives. However, other type of materials can be used, with aggregates sizes up to 2 mm in the standard rotor/stator pin configuration. The mixing quality was optimized to work with mortar flow rates between 5 and 10 L/min (and acc flow rates between 40 and 400 mL/min)
The key advantages of our system are high shear inline mixing with low torque requirements and allows for accelerated mix designs (with rapid vertical build rate, large overhangs…), aesthetic benefits like adding colours, or weight optimization (foaming agents) among others. The mixer is reliable, and easy to maintain due to the flexible liner on the inside. Furthermore, the system follows the KISS principle, is adaptable and can be integrated/expanded upon easily.
