Abstract
A system and method for building three dimensional objects may adjust data used to build the objects to, for example, improve quality or correct for defects. A printer may, for example, accept data representing the object and modify the data according to an adjustment parameter; the printer may build the object according to the parameter. The parameter may be, for example, fixed in the printer, user entered, and/or calculated by the printer. In one embodiment, a support pedestal may be built of deposited material before the object is built.
Claims58
A method for building a three dimensional object the method comprising:
- accepting data representing the object;
- and
- modifying the data according to an adjustment parameter.
A method for building a three dimensional object, the method comprising:
- building a support pedestal by depositing material;
- and
- building the object on top of the pedestal.
A system for building a three dimensional object, the system comprising:
