| Abstract Scope |
Spark plasma sintering (SPS) and stereolithography (SLA) are two sintering and shaping methods with opposite pros and cons. SPS can sinter advanced materials from metals to ultrarefractories but SPS is limited to cylindrical shapes as it uses a uniaxial press. On the contrary, SLA is one of the most precise additive manufacturing methods capable of printing highly elaborated structures but the sintering is based on conventional approaches which significantly limit the materials choice and the quality of the sintered object. We will present a new method called “DEFORMINT” which enable the fabrication of complex shapes by SPS thanks to the coupling of SLA with SPS. Such approach gathers the advantages of SPS in terms of high material properties and the high shapes complexity inherited from the SLA method. We will illustrate this approach by the fabrication of Ti64 turbine blades with high hardness microstructures. |
