StoneFlower3D launches lab-scale 3D printer for concrete, mortars, clays

StoneFlower3D, a Munich-based developer of ceramic and mineral 3D printing hardware, announced in mid-February 2026 a laboratory-scale printer aimed at researchers working with concrete, mortars, clays and other mineral-based pastes. The system is configurable for 1K single-component and 2K two-component printing, and the manufacturer’s specification table lists a nominal material feed rate of up to 5 L/min while also supporting integration with larger pumps up to 10 L/min.

Mechanically the machine ships on a high-grade aluminium alloy and painted steel frame with hardened stainless-steel linear guides and industrial-grade control electronics, including a Duet 6HC controller. StoneFlower3D specifies a 7-inch touchscreen and remote web interface over Ethernet, accepts Marlin/Repetier-style G-code and includes a ready-to-use Cura configuration; compatible slicers named include Cura, Simplify3D, PrusaSlicer and SuperSlicer. Electrical requirements are 110–230 V AC at 1000 W.

Build volumes are configurable to order across axis ranges cited between roughly 50 cm and 300 cm; the company provides a footprint formula of horizontal effective stroke length plus 70 cm and height equal to twice the effective printing height plus 50 cm. Using the manufacturer’s example, a 100 × 100 × 100 cm print volume requires a workspace of about 170 × 170 × 250 cm. A baseline weight of 350 kg is listed for the example configuration.

Material delivery options include continuous mortar/plaster pumps and small piston or ram extruders. StoneFlower3D lists examples such as an automated concrete pump with 55 L capacity and flow up to 10 L/min, and a 5 L ram extruder; a separate article reference noted 3 L/min for a mixing print head, creating a range of reported feed figures across sources. The system supports two-component mixing for rapidly curing combinations, such as cement with accelerator, and the printhead arrangements are intended to simulate higher-pressure on-site pumping workflows as well as smaller laboratory extrusions.

Compatibility specifications preserve concrete mixes including fiber-reinforced formulations with fiber length up to 30 mm, mortars with aggregate sizes up to 6 mm, foamed concrete, clay, porcelain, earth and certain biomaterials. Axis motion is rated up to 150 mm/s on X/Y and up to 15 mm/s on Z, matching the manufacturer table and republished technical summaries.

StoneFlower3D positions the product for material science, construction 3D printing research, prototyping and small-series production rather than for structural certification or full-scale building work. The company frames the system as occupying the mid ground between small desktop clay machines and full construction-scale printers from vendors such as COBOD and ICON.
