Abstract
There is disclosed a method of producing a heating structure, comprising the steps of: (a) using a first laser beam configured to irradiate an encapsulated, sub-surface region of a carbon pre-cursor material below a surface of the carbon pre-cursor material, parameters of the first laser beam being selected to create carbon foam in that encapsulated, sub-surface region and a carbon-based material above the carbon foam; and (b) using a second laser beam configured to remove or ablate the carbon-based material sitting above the carbon foam, parameters of the second laser beam being selected to expose or alter at least some of the carbon foam, to produce a resultant carbon foam material; and (c) configuring the resultant carbon foam material for use as an electrically conductive heating structure.
