I think completely feasible figures, we havent scratched the surface yet for consumer end printing, it could even be higher than that. Imagine what's going to happen on the next Tech breakthrough?? BOOM ! market explosionh...

3 years, going on 4 now... I have not seen consumer printers really improve all that much. SLA is still pricey and FDM has not vastly improved the speed (which let's be honest is the biggest downside to 3D printing... )
Once the machines are printing in the 200-300mm/s range I think that's when we will really see some action in the industry rather than succession after succession of slightly better machines.
