Abstract
A system and a method of mitigating color discrepancies in three-dimensional (3D) printing systems may including a plurality of printing heads may include: printing one or more samples according to one or more sample parameters; obtaining a color offset vector from the one or more samples; receiving a model representing a 3D object, the model comprising a plurality of model printing points associated with respective color; analyzing the model in view of the obtained color offset vector to produce a calibrated data structure, adapted to mitigate color discrepancies; and printing the 3D object according to the calibrated data structure.
Claims20
A method of mitigating, by at least one processor, color discrepancies in a three-dimensional (3D) printing system comprising a plurality of printing heads, the method comprising:
- obtaining a color offset vector from one or more samples;
- receiving a model representing a 3D object, the model comprising a plurality of model printing points associated with respective color;
- analyzing the model in view of the obtained color offset vector;
- producing a calibrated data structure, adapted to mitigate color discrepancies, wherein producing the calibrated data structure comprises modifying the plurality of model printing points to comprise one or more of a transparent envelope region, a clarity enhancement region, a color compensation region and a white region;
- and
- printing the 3D object according to the calibrated data structure.
A system for mitigating color discrepancies in a 3D printing system comprising a plurality of printing heads, the system comprising:
- a non-transitory memory device storing instruction code and a processor associated with the memory device, and configured to execute the instruction code, such that when the processor executes the instructions code, the processor is configured to:
- obtain a color offset vector from one or more samples;
- receive a model representing a 3D object, the model comprising a plurality of model printing points associated with respective color;
- analyze the model in view of the obtained color offset vector to produce a calibrated data structure, adapted to mitigate color discrepancies by modifying the plurality of model printing points to comprise one or more of a transparent envelope region, a clarity enhancement region, a color compensation region and a white region;
- and
- propagating the calibrated data structure to the 3D printing system so as to print a 3D object according to the calibrated data structure.
