<p>SYSTEMS AND METHODS FOR TRANSFORMING REFORMABLE MATERIALS INTO SOLID OBJECTS ABSTRACT OF THE DISCLOSURE A method of forming an object in accordance with a master shape includes providing a container having first and second elastomeric membranes, providing a volume of particles in the container, introducing a sufficient amount of liquid into the volume of particles to cause a mixture of the particles and liquid to assume a formable state, pressing the master shape into the first membrane with atmospheric pressure to cause the mixture to conform to the master shape, and extracting a sufficient amount of liquid from the container to cause the mixture to assume a stable, force-resisting state, thereby forming the object. The formed object may, if desired, be used as a master to form a complementary shaped object.</p> |
