Abstract
Printers are disclosed. An example printer includes a build controller to access metrics of a layer on a work area and to select a dosing profile from a plurality of dosing profiles to fuse the layer based on the metrics.
Claims19
A printer, comprising:
- instructions stored in a memory;
- and
- a build controller to execute the instructions to:
- determine a thickness of a first layer of a build material based on a difference between (a) first height data of the build material including the first layer and one or more other layers and (b) second height data of the build material including the one or more other layers and not including the first layer;
- select a first dosing profile from a plurality of dosing profiles to fuse a first layer based on the thickness determined and a fluid penetration depth of the first layer defined by metrics associated with the first layer;
- cause the first dosing profile to be used to fuse the first layer to generate a first fused layer;
- perform a comparison of metrics associated with the first fused layer to a reference threshold;
- in response to the comparison, update the first dosing profile to generate a second dosing profile;
- and
- cause the second dosing profile to be used to fuse a second layer to generate a second fused layer.

An apparatus, comprising:
- a build metrics determiner to determine a thickness of a first layer of build material associated with an additive manufacturing process based on a difference between (a) first height data of a build material including a plurality of layers including the first layer and (b) second height data of the build material including a subset of the plurality of layers;
- a quality determiner to determine if the thickness satisfies a threshold;
- a dosing profile determiner to:
- when the thickness satisfies the threshold, determine a first dosing profile to fuse the first layer to generate a first fused layer;
- and
- when the thickness does not satisfy the threshold, determine a second dosing profile to fuse the first layer to generate the first fused layer;
- an updater to update one of the first dosing profile or the second dosing profile based on metrics associated with the first fused layer to generate one of an updated first dosing profile or an updated second dosing profile based on a thickness and a fluid penetration depth of the first fused layer defined by metrics associated with the first fused layer;
- the dosing profile determiner to select the one of the updated first dosing profile or the updated second dosing profile to fuse a second layer of the build material.

A method, comprising:
- determining, by executing an instruction with at least one processor, a thickness of a first layer of build material associated with an additive manufacturing process based on a difference between (a) first height data of a build material including the first layer and one or more other layers and (b) second height data of the build material including the one or more other layers and not including the first layer;
- determining, by executing an instruction with the at least one processor whether the thickness of the first layer satisfies a threshold;
- when the thickness satisfies the threshold;
- determining, by executing an instruction with the at least one processor, a first dosing profile to fuse the first layer to generate a first fused layer;
- and
- causing, by executing an instruction with the at least one processor, the first layer to be fused based on the first dosing profile;
- when the thickness does not satisfy the threshold,
- determining, by executing an instruction with the at least one processor, a second dosing profile to fuse the first layer to generate the first fused layer;
- and
- causing, by executing an instruction with the at least one processor, the first layer to be fused based on the second dosing profile;
- updating, by executing an instruction with the at least one processor, one of the first dosing profile or the second dosing profile based on metrics associated with the first fused layer to generate one of an updated first dosing profile or an updated second dosing profile based on a thickness and a fluid penetration depth of the first fused layer defined by metrics associated with the first fused layer;
- and
- selecting the one of the updated first dosing profile or the updated second dosing profile to fuse a second layer of the build material.
