Description
In recent years, metal binder jetting has emerged as one of the most promising and efficient technologies for the additive manufacturing of small metal components in mass production, offering a cost-effective and environmentally friendly alternative to other powder-based AM methods, such as L-PBF (Laser Powder Bed Fusion). Despite its high productivity, one of its main limitations is the need for a standalone sintering step, which impacts processing time and energy consumption. Accelerated sintering strategies, such as FAST/SPS, may offer a viable means of shortening processing times; however, the capabilities of this approach for binder-jetted materials and geometries remain under thorough investigation. In this work, we analyze 17-4PH components produced via a metal binder jetting system (Shop System by Desktop Metal) and investigate the potential of combining binder jetting with FAST/SPS sintering for the rapid prototyping of metallic components. Both pressureless and pseudo-isostatic sintering of the green object have been investigated. In the second case, an inert pressure-transfer powder has been used to maintain the green-body geometry. The influence of the various parameters involved in the printing and sintering process have been investigated. In all cases, the use of FAST/SPS reduces the time required for debinding and sintering, enabling the production of fully sintered samples in considerably less time than conventional sintering.
