I think you're right in that we aren't going to see much of an increase in FDM speed. In fact, I don't think we're going to see much of an increase in the speed of any of the current technologies. By definition, additive manufacturing means building an object one layer at a time. The only ways to increase speed are to reduce the number of layers, invent a material which lends itself to faster layer creation, or find a way to create more than one layer at a time.
It's also important to point out the difference between resolution and accuracy. Resolution typically means layer height. Accuracy typically means X/Y variance – how accurately each layer is being laid down on the X and Y planes. With FDM, accuracy is a huge factor. I've seen a personal FDM printer print at 20 microns, but the layers were still plainly visible. I've also seen a Stratasys Mojo print at 178 microns and the layers were barely noticeable. That's how big a difference X/Y variance can make. A Stratasys FDM printer produces objects of such high quality, they can be used as injection molding prototypes. It's still not as good as SLA, which can produce layers that are both invisible and perfectly smooth to touch, but it's much better than personal FDM.
I'm curious, what kind of resin are you going to use for a functional bike part?
