The manually fed WASP extruder for LDM (Liquid Deposition Modeling)/LAM (Liquid Additive Manufacturing) technology is designed to deliver optimal performance in 3D printing with fluid and dense materials such as cements and geopolymers. Its robust and functional structure allows for direct and continuous material loading into a high-capacity cone, while its modular design enables quick and easy cleaning after each use.

This system integrates a high-precision stepper motor that drives a technopolymer screw responsible for regulating material flow. It also includes a stainless steel funnel with an internal mixer that prevents material hardening and ensures the ideal rheology for consistent extrusion. The manual direct feeding through the hopper allows reloading of material without stopping the process, optimizing productivity, and making it the ideal accessory for the Delta WASP 40100 3D printer.

Thanks to its stainless steel design with internal mixer, cleaning after each printing session is simple, reducing the risk of material solidification inside. For optimal performance, it is recommended to periodically inspect the feed screw and nozzle, as well as to empty and clean the hopper after each use to ensure continuous and uniform extrusion.

The extruder is specifically designed for integration into platforms compatible with LDM and large-format equipment aimed at 3D printing with cementitious and geopolymeric materials. Among its main applications are research projects, architectural prototyping, and the production of industrial or artistic parts requiring precision and control in the deposition of dense materials.

Check that the feed hopper (capacity of approximately 2.5 L) is clean, free of hardened material, and properly secured to the extrusion system.

Ensure that the material mixture (e.g., cement, geopolymer) has an appropriate consistency for extrusion: free of large lumps and excessive trapped air to prevent flow discontinuities.

Pay attention to the nozzle diameter: stainless steel nozzles of 6 mm and 8 mm are available; there is also an optional plastic nozzle that can be cut to the required diameter. Adapt the nozzle to the type of mixture and geometry to ensure optimal flow.

Maintain an active mixture inside the hopper: the system includes an internal mixing blade that prevents the material from settling or hardening before extrusion.

During printing, ensure that the material path from the hopper to the nozzle is free of obstructions and properly aligned, avoiding sharp direction changes that could cause pressure loss or air bubbles.

Program the machine and define parameters for layer height, extrusion speed, and retraction according to the viscosity of the mixture and the nozzle diameter used. As a reference, for dense-fluid mixtures it is recommended to start with moderate extrusion and controlled retraction to prevent dripping or unwanted threads.

After each cycle or at the end of the job, thoroughly clean the hopper, feed screw, and nozzle to avoid residual material hardening and extend the equipment’s service life.

When operating in thermally sensitive environments, monitor ambient temperature (ideally between ~15 °C and ~30 °C) to ensure mixture stability and consistent extrusion behavior.

Verify the extruder’s compatibility with the printer used: this system is indicated as compatible with models such as the Delta WASP 40100 Clay.
