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.
Claims8
A method for building a three-dimensional object by depositing materials onto a printing surface, layer upon layer, within a printing system, the method comprising:
- providing data representing a three-dimensional object, the data comprising X, Y and Z coordinates;
- calculating an adjustment parameter to compensate for a height error caused by material rounding at a top surface of thin walls or structures, said adjustment parameter including a set of non-printed pixels in the interior of said thin walls or structures;
- modifying the data representing the three dimensional-object based on the adjustment parameter;
- and
- printing at least one layer of the three-dimensional object according to modified data.
A system for building a three-dimensional object, the system comprising:
- a controller capable of accepting data representing a three-dimensional object, calculating an adjustment parameter to compensate for a height error caused by material rounding at a top surface of thin walls or structures, the adjustment parameter including a set of non-printed pixels in the interior of said thin walls or structures and modifying in the data representing the three dimensional-object according to the adjustment parameter;
- a printing head connected to the controller capable of depositing materials onto a surface according to said data to form the three-dimensional object;
- and
- a curing unit.
