Patent number: 7402265Abstract: Techniques for generating a stable, force-resisting positive or negative representation of a shape. A state-changeable mixture includes uniform, generally ordered, closely-spaced solid bodies and a liquid carrier medium, with the liquid filling any voids or interstices between the bodies and excluding air or gas bubbles from the mixture. Within the mixture, the solid bodies can be caused to transition from a near-liquid or fluent condition of mobility to a stable, force-resisting condition. To create mobility, a small excess quantity or transition liquid is introduced to create a fluent condition by providing a slight clearance between the bodies which permits the gently-forced introduction of at least two simultaneous slip planes between ordered bulk masses of the bodies at any point in the mixture. Transition to the stable condition is caused by extraction of the transition liquid, removing the clearance between bodies and causing them to make stable, consolidated contact.Type: GrantFiled: December 5, 2006Date of Patent: July 22, 2008Assignee: 2Phase Technologies, Inc.Inventor: Theodore L.

Publication number: 20070152379Abstract: 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.Type: ApplicationFiled: December 12, 2006Publication date: July 5, 2007Applicant: 2Phase Technologies, Inc.Inventor: Theodore Jacobson

Publication number: 20050035477Abstract: Techniques for generating a stable, force-resisting positive or negative representation of a shape. A state-changeable mixture comprises uniform, generally ordered, closely-spaced solid bodies and a liquid carrier medium of relatively similar density, with the liquid medium filling any voids or interstices between the bodies and excluding air or gas bubbles from the mixture. Within the mixture, the solid bodies can be caused to transition from a near-liquid or fluent condition of mobility to a stable, force-resisting condition through introduction and then extraction of a slight excess quantity of the carrier medium. To create mobility, this excess quantity or transition liquid is introduced to create a fluent condition by providing a slight clearance between the bodies which permits the gently-forced introduction of at least two simultaneous slip planes between ordered bulk masses of the bodies at any point in the mixture.Type: ApplicationFiled: April 13, 2004Publication date: February 17, 2005Applicant: 2Phase Technologies, Inc.Inventor: Theodore Jacobson
