| Abstract Scope |
Dimensional shrinkage during sintering of metallic green parts produced by Binderjet 3D printing is anisotropic. Shrinkage is larger along the building direction than in the building plane and even in this plane, it is slightly different along the directions parallel to the printer head and the roller displacement.
The evolution of shrinkage anisotropy during the sintering cycle was investigated by dilatometry and correlated to the microstructural features of the green parts. In particular, the packing of the particles and the evolution of the neck size was characterized by the metallographic analysis and by the measure of thermal conductivity along the three directions.
The influence of gravity was also investigated, by changing the orientation of the parts during the sintering step. |
