In this paper we report on the most recent achievements of the ATLAS 3D Sensors Collaboration in the development of silicon 3D sensors. Results from 3D pixels production for the ATLAS Insertable B-Layer (IBL) are presented, showing the high quality and good process reproducibility of the technology. In view of the future detector upgrades at the LHC, a new generation of 3D pixel sensors will be developed. This will require some new ideas and the solution of technological challenges. Both will briefly be addressed in this paper.
