Claims32
A method of solid free form fabrication of an object, comprising:
- (a) mixing respective amounts of a plurality of materials such as to provide a building material characterized by at least one predetermined attribute of combination;
- and
- (b) using said building material for fabricating a three-dimensional object;
- said steps (a) and (b) being performed in the same facility.
Apparatus for preparing a building material for solid freeform fabrication, the apparatus comprising:
- an input unit, for inputting at least one attribute of the building material;
- a control unit, configured to transmit data pertaining to respective amounts of a plurality of different materials according to said at least one attribute, said control unit being supplemented with an algorithm for determining said amounts;
- a supply unit, operatively associated with reservoirs of said plurality of materials and being controllable by said control unit to supply a respective amount of materials according to said data;
- and
- a container, configured for receiving said plurality of materials.
A system for solid freeform fabrication, comprising a preparation apparatus, for preparing a building material characterized by at least one attribute, and a solid freeform fabrication apparatus, for fabricating a three-dimensional object using said building material, wherein said preparation apparatus is designed and constructed for mixing respective amounts of a plurality of materials according to said at least one attribute, such as to provide said building material.
