Abstract
An example system includes a simulation engine to determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume as a result of printing a particular build. Each thermal state corresponds to a time during the printing or cooling from the printing. The system includes a stress engine to calculate a stress to the powder at the voxel based on the plurality of thermal states. The system includes a degradation engine to determine an amount of degradation of the powder at the voxel based on the stress.
Claims16
A system comprising:
- a processor;
- and
- a memory storing instructions executable by the processor to:
- determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume as a result of printing a particular build, wherein each thermal state corresponds to a time during printing or during cooling after printing;
- determine an initial amount of powder degradation prior to printing, based on an initial color of the powder;
- calculate a stress to the powder at the voxel based on the plurality of thermal states;
- and
- determine an amount of degradation of the powder at the voxel based on the initial amount of powder degradation and the stress, by determining a final color of the powder after printing.
A method comprising:
- simulating, by a processor, a three-dimensional print of a build to determine a plurality of thermal states that will be experienced by powder at a voxel of a three-dimensional print volume due to the three-dimensional print, wherein each thermal state corresponds to a time during printing or during cooling after printing;
- determining, by the processor, an initial amount of powder degradation prior to printing, based on an initial color of the powder;
- calculating, by the processor, a stress based on the plurality of thermal states;
- determining, by the processor, an amount of degradation of the powder at the voxel that will result from the stress, based on the initial amount of powder degradation and the stress, by determining a final color of the powder after printing;
- and
- selecting, by the processor, a three-dimensional print configuration based on the amount of degradation.
A non-transitory computer-readable medium storing instructions that when executed by a processor, cause the processor to:
- determine a first impact of a first environmental factor that will cause degradation of powder at a voxel of a three-dimensional print volume due to printing a particular build;
- determine an initial amount of powder degradation prior to printing, based on an initial color of the powder;
- determine a second impact of a second environmental factor that will cause degradation of the powder at the voxel of the three-dimensional print volume due to printing the particular build;
- and
- determine an amount of degradation of the powder at the voxel based on the initial amount of powder degradation, the first impact, and the second impact, by determining a final color of the powder after printing.
