I have had problem with layer adhesion and brittleness in Colorfabb XT, i can easily crush a thin (2mm thick) print like this http://www.thingiverse.com/thing:8119%C2%A0to%20shattered%20pieces%20in%20my%20hand,%20it%20acts%20really%20brittle%20and%20tends%20to%20break%20along%20the%20layers,%20do%20anyone%20else%20have%20that%20problem? to shattered pieces in my hand without using a lot of force.
I have tried printing it really hot and slow, (260c, 10mm/s), colder and quite slow (245, 15mm/s), and even hotter and faster (255 and 40mm/s), also tried both thin (0,1mm) and thick (0,24mm) layers and i still get a similar result...
Printing at a Ultimaker 1 with custom heated bed at kapton tape.
Anyone had that problem?
You can see how it looks during print here:
