Not sure if this is the right place to post this, but anyway: my 10-day old UM2 works OK on very small pieces, say 1 cm across. Right now I decided to try a larger print, this one https://www.youmagine.com/designs/fanduct-another-idea
and I notice what should be a solid surface is not, it's thin crisscrossing lines. I can make it solid by going in the "tune" menu while it is printing and adjusting the flow rate up to 230% where it started at 100%. That seems like a very large adjustment, when I didn't need to do any adjustment on the smaller pieces. Is this normal and should the adjustment be so large?
I am using Ultimaker blue PLA with 0.1mm layer height, 25% fill, 25 mm/s print speed, Head 205 C, Bed 60 C, fans 100%. Using Cura 14.07 to generate the gcode.

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.
