In any case, for someone not involved in the 3D printing field like myself, it is still amazing to see what is possible even it is "elementary" at the moment.

Yes I thought this was Propane only and there was no sign of lubrication. Also the bearings cannot have been printed as the surface finish of the parts would not be anywhere near good enough. As you say it would have been interesting to see more of what was made from the printer and what they had to do to the parts to be able to use them.
