The Green Polymer Additives team of Emery Oleochemicals, Düsseldorf, Germany, will showcase its new binder system for filament-based Additive Manufacturing at this year’s Formnext, taking place in Frankfurt, Germany from November 19 – 22. The binder is designed for use with a wide range of sinterable metal and ceramic powders to create the filament used in Fused Filament Fabrication (FFF).
Emery Oleochemicals began developing its first binder system for the Metal and Ceramic Injection Moulding (MIM and CIM) process in the early 1990s. With the development of metal and ceramic Additive Manufacturing processes, which use filaments made from sinterable feedstock, the company has developed a new binder to target this market.
The filaments contain a high content of metal or ceramic powder, usually greater than 80 wt.%. After the AM build process, the green part undergoes post-processing steps similar to those required in the MIM and CIM process, involving solvent debinding and thermal treatment or sintering.
