1. A flexible heater suitable for embedding in a wearable, comprising:
a substrate;
a set of additively deposited inks selected, in combination, to achieve a particular fineness, pitch, density and consistency, the selection being by a matching of each additively deposited ink in the set to at least:
a receptivity of the substrate to each of the additively deposited inks;
a conductivity between the substrate to each of the additively deposited inks;
a chemical reactivity as between the substrate and each of the additively deposited inks; and
differing printing and curing methodologies as between each of the additively deposited inks;
each of the additively deposited inks being printed in successive additively printed layers onto at least one substantially planar face of the substrate to form at least:
at least one conductive layer capable of receiving current flow from at least one power source;
at least one resistive layer electrically associated with the at least one conductive layer and comprising a plurality of heating elements capable of generating heat upon receipt of the current flow; and
at least one dielectric layer capable of at least partially insulating the at least one resistive layer;
the particular fineness, pitch, density and consistency being an approximation of subtractive processes when the substrate is unreceptive to the subtractive properties.
