Munich, 17 February 2026 – Munich-based ceramic 3D printing company StoneFlower3D has introduced a new laboratory-scale 3D printer designed specifically for researchers working with concrete, mortars, clays, and other mineral-based materials. The system aims to bridge the long-standing gap between laboratory experiments and real-world construction conditions.

In simple terms, this new printer allows scientists and engineers to test building materials in a controlled lab environment while using methods that closely resemble actual construction processes. This makes research results more reliable when materials are later scaled up for real applications.

The printer supports both single-component and two-component material formulations, such as cement combined with fast-acting accelerators. Build volumes are customizable, with printable dimensions ranging from 50 centimeters to as large as 300 centimeters, depending on the chosen configuration.

The system can handle a wide variety of materials, including standard concrete mixes, mortars with aggregates up to 6 millimeters, fiber-reinforced concrete, clays with fibers up to 30 millimeters long, foamed concrete, porcelain, earth-based materials, and even biomaterials. Material flow rates can reach up to 3 liters per minute, while printing speeds can go as high as 150 millimeters per second.

Designed for Reliability and Ease of Use

Built for long-term laboratory use, the printer features hardened stainless steel linear guides, robust belt drives, and industrial-grade electronics. Users can operate the system through a 7-inch color touchscreen or control it remotely via a web interface.

The printer works with standard G-code and is compatible with popular slicing software used in the 3D printing community, including Cura, Simplify3D, Repetier, Slic3R, SuperSlicer, and PrusaSlicer. Each system ships with Cura software and a ready-to-use configuration file, helping researchers get started quickly.

For material delivery, users can choose from several pumping options. These include an automated concrete pump capable of handling up to 10 liters per minute at pressures of up to 40 bar, a 5-liter ram extruder, or a continuous mortar pump designed for steady material flow. These options allow researchers to match their setup to specific testing needs.

Closing the Gap Between Lab and Construction

Many existing laboratory concrete printers rely on small aggregates and low-pressure extrusion, which often limits how accurately results translate to real construction sites. StoneFlower3D’s system takes a different approach by allowing larger aggregates and higher pressures, closely simulating on-site pumping conditions while remaining within a laboratory environment.

The printer is intended for research, material development, prototyping, and small-series production. It is not designed for structural certification or full-scale building construction but focuses instead on advancing material science and process testing.

The base configuration, which includes the printer frame and mixing print head, starts at approximately €14,500 net and comes with operator training. Customers can customize their setup by specifying build size, pump type, and delivery requirements.

By offering industrial-grade performance in a laboratory-scale system, StoneFlower3D is helping researchers explore the future of concrete and ceramic 3D printing with greater accuracy and confidence.
