An apparatus comprising:
- means to apply heat to a layer of build material when present on a build platform, wherein the build material is to absorb a first portion of the heat and reflects a second portion of the heat;
- and
- a plate disposed between the material heating means and the build material, the plate to absorb the second portion of the heat and re-emit the second portion of the heat to the build material.
A method comprising:
- absorbing, by a plate disposed between a lamp and a material when formed/present on a target zone, energy reflected from the material;
- and
- emitting the reflected energy absorbed by the plate to the material.
An apparatus comprising:
- a plate disposed between a lamp and a layer of material when formed on a build platform, the material to be heated by the lamp, wherein the plate absorbs energy reflected from the material and emits the absorbed energy toward the material.
