Abstract
In an example, a method may include obtaining a first measurement of a first object generated using additive manufacturing apparatus based on object model data and obtaining a second measurement of a second object generated using the additive manufacturing apparatus based on object model data to which a first geometrical compensation parameter has been applied. An effect of the first geometrical compensation parameter may be determined based on the first and second measurements and, based on the determined effect, the first geometrical compensation parameter may be evaluated.
Claims15
A method comprising:
- obtaining a first measurement of a first object generated using additive manufacturing apparatus based on object model data;
- obtaining a second measurement of a second object generated using additive manufacturing apparatus based on object model data to which a first geometrical compensation parameter has been applied;
- determining, using at least one processor, an effect of the first geometrical compensation parameter based on the first and second measurements;
- and
- evaluating, using at least one processor, the first geometrical compensation parameter based on the determined effect of the first geometrical compensation parameter.
Apparatus comprising processing circuitry, the processing circuitry comprising a comparison module and an evaluation module,
- wherein the comparison module is to compare a first data set with a second data set, wherein the first data set is based on measurements of at least a part of an object printed using object model data, and the second data set is based on measurements of at least one object printed using the object model data modified using a first compensation model to compensate for anticipated deformation in object printing;
- and
- the evaluation module is to evaluate the first compensation model based on the comparison.
Machine readable medium comprising instructions which, when executed by a processor cause the processor to:
- determine at least one of a correction factor and an offset parameter to adapt a compensation model for additive manufacturing by comparing:
- a first data set derived from measurements of objects printed by a 3D printer using object model data to which the compensation model was applied, and
- a second data set derived from measurements of objects printed by the 3D printer using object model data to which the compensation model was not applied.
