The present disclosure relates to a method of making a powder of dense and spherically shaped cemented carbide or cermet granules. The present disclosure also relates to a powder produced by the method and use of said powder in additive manufacturing such as 3D printing by the binder jetting technique. Furthermore, the present disclosure relates to a Hot Isostatic Pressing (HIP) process for manufacturing a product by using said powder.

Process for forming tiles which provides for pressing a building material in a cell of a mold of a press by means of an isostatic punch, in which the punch has a compaction surface that is elastically deformable and provided with projections in order to attain cavities on an internal face of a tile and with recesses in order to shape feet projecting on the internal face, in which such punch comprises means for feeding a pressurized fluid and a pressure compensation circuit shaped in order to form pockets of the aforesaid fluid at the recesses.
