3D concrete printing (3DCP) is an advanced digital construction method that uses layer-by-layer deposition of cementitious materials to create buildings, structural elements and customised components without traditional formwork. This technology enables complex geometries, faster build times and greater design freedom. Sika provides specialised concrete admixture technologies developed for 3D printing, helping ensure rapid material extrusion, high precision and reliable performance throughout the printing process.
Digitalisation in Construction
For decades, traditional reinforced concrete has been used as an economical construction method. Today, the construction industry is experiencing a major shift as digital technologies begin to be implemented in the industry.
As digital tools and automated processes grow, the interest in 3D concrete printing (3DCP) grows too. Digitalisation is driving demand for construction methods that increase productivity, reduce labour requirements and enable highly customised designs.
Across the industry, architects, engineers, contractors and research institutions are recognising the potential of 3D printing in construction as they imagine the design flexibility and potential that comes along with it.
Sika aims to support this growing demand by providing advanced materials and admixture technologies specifically developed for 3D concrete printing.
How Does 3D Concrete Printing Work?
- A print head/nozzle is mounted onto a robot arm or gantry.
- The print head/nozzle is connected to a pump with a hose pipe.
- The components of the material are mixed.
- The mix is pumped into the print head/nozzle.
- Lines are extruded on top of each other.
- Additions or admixtures can be added to alter the properties of the mix.
What Equipment is Needed?
- Positive action pan mixer for cementitious materials
- Pump for conveying fresh mixed material continuously
- Sufficient length of pipe to connect the pump and print head
- Robot arm or gantry, including control software
- Print head/nozzle
- Suitable software for translating a 3D computer model into a machine program, often referred to as slicing
What Type of Objects Can Be 3D Printed?
The possibilities are endless when it comes to 3D concrete printing. It allows you to create custom objects not feasible with traditional concrete casting methods. They can be smaller components like architectural furniture, or large-scale, fully-printed buildings and civil infrastructure.

Sika Products
Sika provides a complete range of solutions for 3D concrete printing, enabling rapid, precise and cost-effective production tailored to your project requirements. With over a century of experience in cement and admixture technology, Sika can support businesses in launching or enhancing their 3D concrete printing operations. In addition to 3DCP products, Sika offers a wide range of solutions designed to add value across every stage of your construction project.
Sika 3D Concrete Printing Solutions
Sika provides cementitious materials for printing objects with your equipment. There are numerous types of mixers, pumps, and robotics on the market. To achieve a successful print, the equipment and material must work together. All these factors play a significant role in achieving optimal results of the finished concrete. Sika works with our partners to evaluate the print quality and find ways to improve it.
Types of information we can discuss:
- What type of equipment do you use?
- What type of objects do you print?
- What line widths, heights, printing speed and ambient temperatures are you working with?
- What are your open time, setting time, strength and performance requirements?
- Do you have any special requirements e.g., testing, colours, maximum grain size, packaging?

FAQ
Please fill out the contact form here, and we will reply to your request.
No, Sika does not sell 3D concrete printing equipment.
Sika has worldwide production factories. Where possible, we like to produce locally to reduce transportation costs and time. If you would like to use local concrete to 3D print, Sika can also assist with pre-testing the concrete using Sika admixtures.
Yes, Sika has a range of concrete admixtures and mortar additives that can help to improve the printing consistency according to the project requirements. Contact one of our techical representatives here to discuss your requirements in more detail.
Yes, Sika can help support with concrete mix design. We support ready-mix and precast concrete manufacturers daily.
