Ok Steve, I'll call you Mr. X then
Oh, can't wait. This will surely bring some light in this underextrusion matter.
Very interesting. I think right now bigger leaps in 3D printing will be made with new materials than with other printing technologies or improvements to existing ones. Because as interesting as say metal printing would be, the time it takes for this new technique to stabilize might be quite long. In the meantime and with the existing tech, newer interesting materials will produce far more interesting results.
I think people here on the forums would be able to give great insights in demand for new material. Also there is a lot of experience. You could start a discussion thread about it.
