Description of the continuous feeding

2 DESCRIPTION OF THE CONTINUOUS FEEDING
The Continuous Feeding System (or CFS for short) is the new WASP product for the ceramic sector.
The CFS is the world’s first continuous supply system for dense fluid materials for additive manufacturing that
replaces the limited capacity tank with a virtually infinite power system.
The CFS can be fed continuously without ever interrupting the printing process. The material, after being mixed
and brought to the correct consistency for printing, can then be introduced before the start of the system from
the circular inlet hole during the printing phase.
However, it no longer matters that the material is compacted and degassed before being introduced, since the
continuous movement of the mixer can easily remove all the air bubbles. An outcome that is difficult to achieve
with standard tanks.
The lower transport area has an auger that has the task of pushing the material up to the extruder mounted on the
printer. The connection PTFE/INOX tube is in fact solid enough to work in harmony with the whole system without
creating any particular effort either for the 3D printer or for the CFS.
All areas exposed to contact with the wet material are made of resistant stainless steel in order to prevent
oxidation. The system can be easily disassembled and is precisely designed for cleaning and maintenance.
