Abstract
The method comprises sequentially forming a plurality of layers in a configured pattern corresponding to the shape of the object, thereby forming the object. The formation of each layer comprises dispensing at least one uncured building material, and at least partially curing the uncured building material, wherein for at least one layer, the curing is initiated at least t seconds after commencement of curing of a layer immediately preceding that layer. The t parameter is longer than the number of seconds required for the formation of the layer.
Claims26
A method of additive manufacturing of a three-dimensional object, comprising sequentially forming a plurality of layers in a configured pattern corresponding to the shape of the object, thereby forming the object;
- wherein said formation of each layer comprises dispensing at least one uncured building material, and at least partially curing said uncured building material, and wherein for at least one layer of said layers, said curing is initiated at least t seconds after commencement of curing of a layer immediately preceding said at least one layer, said t being longer than an overall time required for said formation;
- said method further comprising receiving characteristic heat deflection temperature (HDT) data of said at least one cured building material, and selecting a value of said t responsively to said HDT.
(canceled)
A system for additive manufacturing of a three-dimensional object, comprising;
- a dispensing unit configured for dispensing at least one type of uncured building material;
- a curing unit configured for curing said uncured building material;
- and
- a controller configured for operating said dispensing unit and said curing unit to sequentially form a plurality of layers in a configured pattern corresponding to the shape of the three-dimensional object, such that for at least one layer of said layers, said curing is initiated at least t seconds after commencement of curing of a layer immediately preceding said at least one layer, said t being longer than an overall time required for said formation,
- wherein said controller is configured to receive characteristic heat deflection temperature (HDT) data of said at least one cured building material, and to select a value of said t responsively to said HDT.
