Drill template tool with integral seal

The disclosure provides in one embodiment for an integral seal for a drill template tool for a structure having an outside mold line surface fabricated according to a precise definition using computer aided design (CAD). The integral seal comprises an inner surface in contact with an interior portion of a continuous groove portion formed in a bottom surface of a vacuum housing of the drill template tool. The integral seal further comprises an outer surface in contact with the structure. The integral seal is formed in the groove portion on the bottom surface of the vacuum housing, and the groove portion is formed using one of selective laser sintering, fused deposition modeling, or stereolithography, during fabrication of the drill template tool. The integral seal prevents leakage of fluids and debris generated by a drilling process of the structure.
