Hi, I am having problems with my parts being very brittle. Especially bar clamps break very easily.
I am printing PLA at 185°C, nozzle dia. 0.5mm, layer height 0.3mm
Obviously, the layers don't bond very well.
From what I learned so far there are three main reasons for this:
A) too low temp. --> I already imcreased the temp from 175 to 185, with no improvement.
too little material used? The weird thing here is that other printing problems I have (too small holes, thin wall object boundary (http://www.thingiverse.com/thing:37137) thicker than it should be) indicate that I am rather using too much material.
C) layer height too large --> I decreased to 0.2mm with no improvement
I find this qutie confusing. Should I print with ever higher temp. but slower?
If anyone had similar problems, I would be grateful for comments.
Thanks!
