Currently FSL3D is shrinking the thickness of the laser trace. They are aiming at 50um which will reduce printing speed by approximately a factor of two, but will increase the resolution by 5!

I am pretty confident this printer will be a lot faster then the FDM competition in this price range. If speed is the main concern for you, you should consider the DLP alternatives. You may have to make compromises in building size and resolution, but you will have a fair chance to get a faster system.
