...how long do you think a single printer has to run to print that bike?
How many issues will there be with warping, under extrusion and waredown of the print head?

FDM printed parts have really good strength in layer direction. Against layer direction you have a weaker material and a very high chance of micro-cracks getting in between the layers during a longer tour.
Anyway, the design, the engineering and the CAD modelling seems to be really, really good It shows what is possible with this technology, but I don't see this on the market in the future.
