Hybrid additive/subtractive manufacturing system to prepare dense and complex shape ceramic parts
Abstract
International audience ; As the conventional binder jetting method is limited in terms of achievable density and finish surface, a new concept of hybrid subtractive/additive manufacturing system has been recently developed. The system relies on a modified binder jetting machine which integrates a slurry-based deposition system and a pulsed laser. The slurry-based deposition system is a spray device which can be an alternative to the recoating blade traditionally used to spread layers of coarse powder. By using slurry containing fine ceramic grains, thin layers of highly packed powder can be obtained which is highly beneficial to improve the sintered density of printed parts. The other limitation of binder jetting is the rough finish surface. Thanks to the smallness of the spot size, a pulsed laser is a good option to refine the contour of each printed layers thus enhancing the overall part resolution and smoothness.The present work exhibits some preliminary results obtained using this new concept of hybrid machine. Parts made in alumina have been produced demonstrating the advantages and current limitations of the new approach. Alumina powders have been processed to change the particle size, distribution and morphology in order to assess the influence of these characteristics on printing behavior. Furthermore, process parameters were studied such as layer thickness, deposited amounts of binder on each layer, spreading speed of recoater. This work also reports the results of the first tests using the laser to refine the borders of each printed layer. The influence of this treatment on the finished surface of the sintered parts is highlighted.
