Daemon3D Print is pleased to offer the Wasp Clay Printing category on our webshop, WASP has launched the first professional extruder for ceramic materials adaptable to other 3D printers. The Liquid Deposit Modelling (LDM for short) extruder is the new extruder for ceramic materials and it can be adapted to most 3D printers on the market.

 

WASP has launched this product in an aim to promote the print of fluid-dense materials and advanced ceramics in the world. Through development by WASP they have created an extruder, which is able to interrupt and restart the extrusion flow. This new LDM extruder reaches a level of precision, which is close to that of plastic polymers extruders because of the combination of a screw extruder and a pressure extruder. With this new technology it’s possible to control, with accuracy, the flow of material and with the use of retraction, to interrupt deposition.

 

The bubble eliminating extruder removes air bubbles in the clay mixture and the extruder has an extrusion controlling system with retraction option.

 

The WASP clay kit 2.0 has a 3kg tank (which can also be substituted with a 15kg one), the tank can be refilled or cleaned by opening the caps located at either end. Inside the tank there is a piston with two 4 bar gaskets which pushes the material through the Teflon pipe into the extruder. The cap located on the back has a safety valve set at 8 bar. On the stand of the tank there is a pressure regulator and a non-return valve, inside the chamber the material is funnelled toward a screw which pushes the clay out producing an effective pressure of 40 bar without damaging the system.

 

This new technology from WASP allows the air to outflow upward, eliminating bubbles inside the mixture. Thanks to the screw extruder, the density of the printed clay materials is also higher, reducing the time for the state change from liquid to solid, eliminating the risk of the printed object collapsing.

 

The LDM extruder was created to be installed on WASP 3D printers, but can be adapted for most existing FFF machines. It’s simple to install the LDM extruder, as WASP provide a print file for the supporting cover that is required, and after that all that is required is that the extruder must be linked to the extruder signal lines and the “number of steps per millimetre” set to 400.
