Abstract
An example method to control a 3D printing system is described. In that example a print agent is selectively deposited onto a portion of a build material layer and based on a reflectance of the portion of the build material layer, an amount of energy to be applied to the portion is determined.
Claims15
A method of controlling a 3D printing system comprising:
- forming a build material layer;
- selectively depositing a print agent onto a portion of the build material layer;
- based on a reflectance of the portion of the build material layer, determining an amount of energy to be applied to the portion;
- and
- applying the determined amount of energy to the portion of the build material layer.
2 more elements
A 3D printing system comprising:
- a printhead controllable to selectively deposit a print agent onto a surface of a build material layer based on a three-dimensional object model;
- a controller to determine an amount of energy to be uniformly applied to the surface based on a reflectance of that surface;
- and
- an energy source to uniformly apply the determined amount of energy to the surface.
1 more element
A non-transitory computer readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
- control a printhead assembly to selectively deposit at least one print agent onto a surface of build material based on a three-dimensional object model;
- adapt an amount of electro-magnetic radiation to be uniformly applied to the surface of build material based on a reflectance of the surface;
- and
- control a fusing lamp to apply the adapted amount of electro-magnetic radiation to the surface of build material.
