Enables Long-Distance & High-Pressure Stable Feeding

As a core link between the concrete mixer and 3D printer nozzle, the auxiliary pump supports material delivery over 10-50 meters (adapting to large-scale construction or on-site printing). Its high-pressure output system avoids slurry interruption or accumulation during transportation, ensuring continuous and uniform slurry supply to the nozzle—effectively preventing printing layer gaps and component scrapping caused by feeding breaks.

Precisely Controls Feeding Speed to Match Printing Rhythm

Equipped with frequency conversion or flow control valves, the pump adjusts slurry delivery volume in real time based on 3D printing parameters (e.g., nozzle moving speed, layer height, component density). It prevents component deformation from excessive feeding and internal voids from insufficient feeding, directly guaranteeing printing accuracy and component structural integrity.

Adapts to High-Viscosity Slurry & Protects Printer Nozzle

Designed with anti-adhesion and strong pushing structures (screw/plunger type), the pump smoothly conveys high-viscosity 3D printing concrete slurry (to avoid post-printing collapse). It also features a secondary filtration function to block tiny impurities missed by the mixer, preventing nozzle clogging and reducing printer maintenance costs—while improving the surface finish and internal density of printed components.
