With a build area of big dimension and its versatility, concrete 3D printer Delta WASP 3MT CONCRETE offers a new option in additive manufacturing of concrete mortars.
This concrete 3D printer, Delta WASP 3MT INDUSTRIAL 4.0 LDM is optimized for large 3D printing and can be configured with the following tools:
LDM WASP Extruder XXL* screw extruder for cement mortars, mixtures based on raw earth and natural fibers and clay based mixtures with continuous feeding system:
- Nozzle diameter: 8 to 30 mm.
- Clay: 8–18 mm
- Cement mortars and natural mixtures: 18–30 mm
- Tool standard with the printer
LDM WASP Extruder XL screw extruder for dense fluid materials: clay, porcelain, stoneware with 3/5 kg tank.
- Nozzle diameter: 4–6–8 mm.
The LDM WASP Extruder XXL is feeded using a mortar pump that delivers the material through a tube. The flow rate is controlled via a pressure sensor mounted on the extruder inlet that is capable of continuously measuring the pressure and therefore the flow of outbound material to achieve the best extrusion conditions. By using the pump control unit, all the pumping variables can be set according to the type of material and to the paste consistency.
Delta WASP 3MT CONCRETE is manufactured in metal with strong steel cored belts and is equipped with special grid panels to work in complete safety.
With this dimension 3D printer is possible to create concrete mortar products thanks to an extrusion system equipped with a special mortar pump and a screw-driven extruder.
The MDF pallet bed and the removable front lower beam allow to remove, once the printing activity is completed, the objects printed both via pallet truck and forklift.
