RP'rs and Sadegh

I have done some initial test on our LOM parts.

Tensile results have shown that part strength along the length of the paper
roll(x) is twice that of the part strength across the width(y).

Stress in X = 72 N/mm2
Stress in Y = 36 N/mm2

I have not yet found the machine time to build specimens in Z direction.

Hope this is of interest.
