Make the mold with the dough
Don't know what material are you going to make up, but the estimate is made of liquid class can be solidified material. So note that, if the material to be heated to a liquid to prevent the high temperature burn silly putty cavity (silly putty is usually made of flour and salt). In addition to prevent leakage of liquid. (recommended materials choose gesso)
When injecting the material into the dough, be careful to avoid excessive fluid pressure.
Theoretically possible, but be aware of the following points: When taking the true model out, try to avoid the distortion of the internal cavity of the dough. The deformation of the cavity directly affects the later production accuracy.
