Abstract
A method for forming a three dimensional object, the method including the steps of generating a digital representation of the object, generating a digital representation of a build style lattice having a substantially uniform, conformal tetrahedron structure, overlaying the respective representations of the object and the build style, intersecting the overlaid representations to generate a digital representation of the object incorporating the build style; and fabricating the digital representation of the object incorporating the build style by solid free form fabrication.
Claims27
A three dimensional object formed through use of a free form fabrication technique, said object comprising:
- a boundary skin;
- and
- an open-celled lattice integrally formed with and extending from the skin, the open-celled lattice including a plurality of tetrahedrons, each tetrahedron including four legs, each leg extending from a node and having a uniform length and thickness, the legs extending from the node and positioned with respect to one another so that an angle between any two legs is equal to an angle between any two other legs,
- the boundary skin and the open-celled lattice including a series of layers of photosensitive material, each layer successively cured with an ultraviolet laser beam.
