Abstract
In an example, a machine-readable medium stores instructions which, when executed by a processor, cause the processor to: update a 3D printing geometrical compensation model with at least one correction determined using a combination of a dimensional correction determined from measurements of objects generated using a first geometrical compensation and a dimensional correction determined from measurements of objects generated using a modified version of the first geometrical compensation.
Claims15
A method comprising:
- receiving, at a processor, at least one of a first and a second geometrical compensation to compensate for anticipated deformations in additive manufacturing;
- and
- determining a third geometrical compensation based on a combination of
- (i) a first compensation correction for a first build operation which utilised the first geometrical compensation to generate a first set of objects, and
- (ii) a second compensation correction for a second build operation which utilised the second geometrical compensation to generate a second set of objects,
- wherein:
- the first compensation correction was derived to correct for deviations between the dimensions of the first set of objects and their intended dimensions;
- the second compensation correction was derived to correct for deviations between the dimensions of the second set of objects and their intended dimensions;
- and
- the second geometrical compensation is a modified version of the first geometrical compensation.
Apparatus comprising processing circuitry, the processing circuitry comprising:
- a compensation correction module to update a geometrical compensation parameter with a correction parameter determined using a combination of a dimensional correction determined from measurements of objects generated using a first geometrical compensation and a dimensional correction determined from measurements of objects generated using a modified version of the first geometrical compensation.
A machine-readable medium storing instructions which, when executed by a processor, cause the processor to:
- update a 3D printing geometrical compensation model with at least one correction determined using a combination of a dimensional correction determined from measurements of objects generated using a first geometrical compensation and a dimensional correction determined from measurements of objects generated using a modified version of the first geometrical compensation.
