The laser penetrates the filament heating it internally instead of only heating the outer surface. It's near-infrared (808 nm) so it heats the small cylinder of filament essentially uniformly throughout its volume. It's also nice because they can vary laser power much more effectively than you can vary the temperature of a conduction surface. https://arxiv.org/pdf/1709.05918.pdf

Checkout the second to last page for pictures: https://arxiv.org/abs/1709.05918 I think you bring up a good point about the lack of precision at high speed. I think the next big thing in this industry is going to be diving into the factors behind the 'sloppyness' you mention. > I'd like to know how well the auger is able to do this. I can answer this one! it's actually more like a nut on a bolt, instead of an auger, meaning it can reverse just fine.
