Additive Manufactoring by Extrusion
Whereas conventional AM processes involve the application of discrete volumes of different consistencies, the AMbE process is characterized by the continuous application of strands of ceramic and related materials, whereby strands with a wide variety of cross-sections can be extruded depending on requirements thanks to the largely variable geometry of the nozzle.
Not only for plastics and metallic materials, additive manufacturing is gradually establishing itself as an alternative to existing molding processes such as injection molding, dry pressing, film casting, etc.

Economical & efficient - New perspectives through AMbE
Within the scope of the various AM variants, the "AM by extrusion" variant, both in the form of thermoplastic extrusion with immediate curing, and in the form of "cold extrusion" without immediate curing, opens up interesting possibilities in different fields:
The ability to use different nozzles to shape the continuously exiting ceramic strand as a compact or perforated profile, rather than generating the workpiece from discrete dots or layers, is likely to prove an advantage, particularly in terms of the efficiency of the process.
