Hello! First I want to start by saying thank you to this community. I have learned a tremendous amount about 3D printing from these group/thread. This is my first r post ever so please bare with me and thank you so much for answering my question. I am trying to print some threads using Simplify 3D. I am trying to print at 100% infill because this application needs an incredible amount of strength. One of the problems that I am facing with the print is where I need threads. For some reason I cannot get my slicing software to fill in the area behind the threads. Everything else fills perfectly which is really odd. Are there any settings in simplify 3D that I can change to fix it and prevent the occurrence? Thanks so much!
