A curable composition containing a functionalized poly, an acryloyl monomer, and a filler is compression molded by a method that includes introducing the composition to a mold, closing the mold and applying a first temperature of about 120 to about 200\xb0 C. The switching may be based on the device determining that tissue impedance stability has occurred. During the operation of the printing system, the lines are reprinted and the distance between the two lines compared to the initial distance stored in association with the printheads that printed the lines.
