Binder Jetting – at once the new kid on the block yet one of the industry’s earliest processes – holds the promise of taking metal Additive Manufacturing into the territory of true high-volume production. Yet progress towards this goal appears to be struggling, with machine sales lower than many hoped and two new ‘big players’ appearing to be holding back on full commercialisation. In this report, Joseph Kowen considers the development of this industry to date, the obstacles facing its growth, and, of course, the recent announcement of two of Binder Jetting’s biggest rivals coming together in the most unexpected acquisition.

In this article, Dr Samuel von Karsa-Wilberforce, Emery Oleochemicals, Germany, and co-authors report on the tensile strength of sintered 316L specimens produced via Fused Filament Fabrication (FFF), a Material Extrusion (MEX)-based Additive Manufacturing process. The parameters studied include printing nozzle temperature, flow percent or extrusion multiplier and nozzle diameter of print head. The 316L feedstock filaments are based on Emery Oleochemicals’ evolutionary binder system, which has been used in MIM for more than thirty years. The partner in the study for debinding, sintering and mechanical testing is CMG Technologies Ltd, UK.
