That’s a great article, and even though it’s about petg and carbon fiber I am sure pla + carbon fiber has similar results – increased rigidity and brittleness. To me, and I don’t claim to possess any knowledge in the subject, the increased rigidity seems desirable for this application. I guess my questions then become, is it a good thing? Will it be too brittle?
Since it will only take a little time and a bit of cheap PLA to find out I am willing to go down this route. But, there are many people reading this, I am sure, who are much more knowledgeable than myself and was hoping they could provide a basic sanity check before I go forward.
