Abstract (en)

[origin: EP2397245A1] The set of layers comprises a first layer (10), and a second layer to be stacked on the first layer in a direction of stacking. The first layer includes three non-functional projections (20, 21, 22) that extend in the direction of stacking and along non-colinear axis, and a functional projection (16, 18) with shield, where the functional projection is in contact with a refractory material when the two layers are stacked. The second layer comprises a recess capable of completely covering the non-functional projections when the two layers are stacked. The set of layers comprises a first layer (10), and a second layer to be stacked on the first layer in a direction of stacking. The first layer includes three non-functional projections (20, 21, 22) that extend in the direction of stacking and along non-colinear axis, and a functional projection (16, 18) with shield, where the functional projection is in contact with a refractory material when the two layers are stacked. The second layer comprises a recess capable of completely covering the non-functional projections when the two layers are stacked so as to prevent contact between the non-functional projection and the refractory material. A height of the non-functional projection in the direction of stacking is greater than a height of the functional projection in the same direction of stacking. Independent claims are included for: (1) a non-permanent mold; and (2) a process for making a model for manufacturing a part by a non-permanent mold made of refractory material.
