1. A method comprising:
forming an as-deposited coating on a substrate by depositing a filament via a filament delivery device, wherein the filament includes a sacrificial binder and a powder;
removing substantially all the binder from the as-deposited coating; and
sintering the as-deposited coating to form a thermal coating; wherein the thermal coating is configured to ablate in response to absorption of energy from an external environment, wherein the ablation of the thermal coating reduces the energy transferred to the substrate, and wherein the ablation of the thermal coating reduces transfer of heat from the external environment through the thermal coating to the substrate to maintain the substrate at a temperature below a melting temperature of the substrate.
