SKU N/A Category Tag


LDM WASP Extruder is a ceramic extruder, a professional instrument for the deposition of dense fluid material as clay mixture and experimental materials. It is equipped with a screw system capable of regulating the output flow of the material, allowing a rapid flow interruction and a good retraction control.

Bubble eliminating extruder, it eliminates air bubbles in the mixture.
Extrusion controlling system with retraction option.
Outward pressure multiplier.

1.2 mm steel nozzle ideal for accurate printing, medium difficulty.
2 mm steel nozzle ideal for fast printing, low difficulty.

WASP’s work has always been focused on the development of systems that allow the use of functional materials like ceramics, porcelain, clay, alumine, zirconium and advanced ceramics, in order to promote digital handicraft and self-production. By launching this new ceramic extruder the group aims to promote the print of fluid-dense materials and advanced ceramics in the world.

In two years of time and after experimenting all the possible combinations of pressure, nozzles and materials WASP has created a model of extruder which is able to interrupt and restart the extrusion flow.

The new LDM WASP Extruder can reach a level of precision which is very close to that of plastic polymers extruders thanks to the combination of a screw extruder and a pressure extruder. With this technology it is possible to control with accuracy the flow of material and also to use retraction to interrupt deposition.


Adaptability to other machines

The extruder was created to be installed on WASP printers, but can be adapted to most of the existing machines.

It is very easy to install WASP LDM extruder on other machines. Firstly, it is necessary to print the supporting cover (the source files are provided by WASP). Secondly, the extruder must be linked to the wire and the “number of steps per millimeter” must be set to 400.  This configurations are provided by the most common slicing softwares, like Slic3r or Cura.
