Abstract
In an example, a method includes identifying, by processing circuitry, a feature of less than a threshold size of an object to be generated in additive manufacturing. In some examples the method further includes determining, by processing circuitry, a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object. The method may further include determining, by processing circuitry, a second density of print agent to be applied to build material when generating another feature of the object.
Claims17
A method comprising:
- identifying, by processing circuitry, a feature of less than a threshold size of an object to be generated in additive manufacturing, by:
- reducing an initial volume of the object by a threshold amount in at least one spatial dimension to provide an eroded object volume;
- increasing the eroded object volume in the at least one spatial dimension by the threshold amount to provide a dilated object volume;
- comparing the dilated object volume to the initial object volume;
- and
- identifying differences between the dilated object volume and the initial object volume as a candidate feature of less than a threshold size;
- determining, by processing circuitry, a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object;
- determining, by processing circuitry, a second density of print agent to be applied to build material when generating another feature of the object;
- and
- additively manufacturing the object such that the print agent is applied at the determined first density when generating the identified feature of the object and is applied at the determined second density when generating the another feature of the object.
A non-transitory computer-readable data storage medium storing instructions executable by processing circuitry to perform processing comprising:
- identifying a feature of less than a threshold size of an object to be generated in additive manufacturing;
- determining a first density of a print agent to be applied to build material when generating the identified feature of the object based on an intended flexibility of the feature of the object;
- determining a second density of print agent to be applied to build material when generating another feature of the object, by:
- determining an initial density value;
- and
- modifying the initial density value for at least one location on a layer of build material based on one or more than one of:
- a predicted or measured temperature distribution within a build chamber;
- a location of the object within a build chamber;
- proximity of the object to another object to be generated within the build chamber;
- and
- anticipated distortions of the object;
- and
- causing the object to be additively manufactured such that the print agent is applied at the determined first density when generating the identified feature of the object and is applied at the determined second density when generating the another feature of the object.
