Abstract
Method for manufacturing three-dimensional objects (W) consisting of superimposed layers (L) of a base material (M), liquid at ambient temperature and capable of solidifying permanently following a stimulating action, comprising the following operations: spreading a layer (L1) of the liquid base material (M) on the preceding layer (L), selectively exposing the layer (L1) to stimulation in one or more predefined areas (K), repeating the spreading operation and the exposure for each successive layer of the three-dimensional object (W), cooling the layers (L) to a predefined operating temperature below ambient temperature before the stimulation, in order to make the base material (M) solidify.
Claims14
Method for manufacturing three-dimensional objects consisting of a plurality of superimposed layers of a base material, liquid at ambient temperature and capable of solidifying permanently following a stimulating action, comprising the operations described below:
- spreading a layer of said liquid base material on a preceding layer;
- selectively exposing said preceding layer to said stimulation in one or more predefined areas;
- repeating said spreading operation and said exposure for each successive layer of said three-dimensional object, and
- cooling said layers to a predefined operating temperature below said ambient temperature before said stimulation, in order to make said base material solidify,
- wherein it comprises an operation for spreading a base layer of said base material before spreading the first layer of said three-dimensional object, said base layer not being subjected to said stimulation.
