Manufacturing and ReadinessThis model has been rigorously verified through industry-standard mesh repair protocols. It is delivered as a fully watertight, non-manifold-free, closed solid body. The geometry is completely prepared for high-resolution resin 3D printing and subsequent investment casting.
