Super-fast drying concrete from Sika: perfect for creative objects

At Studio DrieDay, we frequently work with this concrete. It is designed for ultra-fast drying, precision, and high production quality — making it ideal for printing creative objects. Printing small layers, creating overhangs, and under the right conditions, the results are truly impressive. 


Material specifics

  • A combination of the cementitious powder and a liquid polymer is mixed in the mixing station. During printing, an activator is added in the printhead, enabling setting ‘on demand’ — giving you full control over drying time and strength development.
  • Thanks to this flexible activation, you can not only print at high speed but also move prints immediately after printing. The automation therefore significantly increases efficiency.

The benefits at a glance:

  • Fast printing speeds and immediate placement — prints can be moved almost instantly after printing, without long waiting times.​
  • Refined finish – fine particles create a smooth surface in light grey or in a color of your choice.
  • High accuracy – precise setting ensures consistent, high-quality prints without deformation.
  • High productivity – without traditional formwork, with a longer workable period (pot life), allowing interruptions without loss of quality.

In short: with Sika’s 2K solution you combine an innovative, automated printing process with a fast-drying, adjustable material that delivers excellent performance — perfect for those seeking efficiency, quality, and flexibility in 3D concrete printing.
