Live build part heuristic simulation Rather than just remove blob errors on every 10th layer, develop a live model of the build progress of the part and update shape with 3D map of error blobs, then modify follwoing layer G code to take in to account blobs, and thereby only intervene subtractively when blobs effects outside of the part.

Polishing Plasma through the addition of argon and a defocused beam, polishing out roughness from a typical powder printed finish Rq of 25 nm to a polished surface Rq of 4 nm is possible , there are other low tech polishing methods that may be easier eg. Tumble finishing. EBeam Polishing [1]
