US 2019/0168453 A1 · PRINTER WARMING DEVICE CONTROL

Abstract

According to an example, a printer may include a warming device to apply energy onto a region of a plurality of regions of a layer of build materials. The printer may also include a controller that may calculate, based upon the region upon which the warming device is to apply energy, an energy curve to be applied to the warming device between occurrences of a plurality of events, in which the energy curve defines timings and levels at which the warming device is to be operated between occurrences of the plurality of events. The controller may also control the warming device to be operated to apply energy onto the region according to the calculated energy curve.

Dependent claims

A printer comprising:

a warming device to apply energy onto a region of a plurality of regions of a layer of build materials;
a controller to:
calculate, based upon the region upon which the warming device is to apply energy, an energy curve to be applied to the warming device between occurrences of a plurality of events, wherein the energy curve defines timings and levels at which the warming device is to be operated between occurrences of the plurality of events;
and
control the warming device to be operated to apply energy onto the region according to the calculated energy curve.

2 more elements

A method comprising:

accessing, by a controller, a master energy curve, wherein the master energy curve defines timings and levels at which a control warming device is to apply energy onto build materials in a control region to maintain the build materials within a predetermined temperature range between occurrences of a plurality of events;
and
calculating, by the controller, a first energy curve for a first warming device from the accessed master energy curve, wherein the first energy curve defines timings and levels at which the first warming device is to be operated to apply energy onto build materials in a first region;
and
controlling, by the controller, the first warming device to be operated to apply energy onto the first region according to the calculated energy curve.
