WASP launch a new professional Kit with extruder, LDM (Liquid Deposit Modeling) Wasp Extruder for fluid-dense and ceramic materials.
-Bubble eliminating extruder, it eliminates air bubbles in the mixture
-Extrusion controlling system with retraction option
-Outward pressure multiplier until 40 bar in the screw extruder
The WASP LDM Clay Kit 2.0 includes a 3 litre tank (which can be substituted with a 5 litre one, on specific demand). The preceding needle experimental models did not allow middle size printing because of the limited amount of mixture they could contain.
The tank can be refilled or cleaned simply by opening the caps located at the extremes. Inside, there is a piston with two 4 bar gaskets which pushes the material through the teflon pipe (diameter 12mm) which supplies the extruder. The cap located on the back has a safety valve set at 8 bar.
This technology allows the air to outflow upward , eliminating the probability of finding bubbles inside the mixture. Like for a common pressure extruder, if there were bubbles the flow would be interrupted and the print would be damaged.
Furthermore, thanks to the screw, the density of the printing materials is higher. This allows to reduce the time for their change of state, from liquid to solid, thus eliminating the risk of collapse of the printed object.
