Pump-fed extrusionRobot & gantry integrationConfigurable mounting
Designed for the realities of concrete printing.
EX-5 is designed around practical integration, adaptable material delivery, and straightforward maintenance. Final performance depends on the connected equipment, mix, and operating conditions.
Robotic integration
Adaptable to robotic arms, gantry platforms, and custom motion systems after mechanical and controls review.
Material-aware setup
No single mix fits every process. Formulations, nozzle selection, and delivery conditions require application testing.
Serviceable construction
Industry-standard components and accessible connections support maintenance and system-level adaptation.
Built to work within your printing system.
EX-5 is the extrusion component in a larger material-delivery and motion-control workflow. Pumps, hoses, robotics, and controls must be selected and integrated for the specific job.
01 / MATERIAL SUPPLYMaterial pump
Mix preparation, pumping, and feed delivery are selected for the application.
02 / EXTRUSION HEADRiver EX-5
Configurable extrusion interface for controlled deposition within the print system.
03 / MOTION SYSTEMRobot or gantry
Toolpath, travel speed, and motion synchronization are managed by the host system.
Configuration dependent. This is a conceptual arrangement, not a claim that a pump, motion system, or additive dosing equipment is included with every EX-5 configuration.
EX-5 technical overview.
The EX-5 is offered as a configurable extrusion component. Hardware interfaces and operating parameters should be confirmed against the proposed application before purchase.

Research and pilot workflows evaluating formulations, toolpaths, and deposition behavior.
Common integration questions
Will EX-5 work with my existing robot or gantry?
Potentially. Mounting, payload, pumping interfaces, operating envelope, and control synchronization need to be reviewed for the specific platform.
Does the EX-5 include a material pump?
The EX-5 is described as pump-fed. Confirm which external pumping, hose, controls, and accessory components are included in your quoted configuration.
Can it process my concrete mix?
Mix suitability depends on particle size, rheology, pumpability, hose configuration, and nozzle selection. A material compatibility review and test plan are recommended.
Is inline accelerator dosing included?
Do not assume it is included. Injection and dosing capabilities are configuration-dependent and must be confirmed before ordering.
