The industry standard for fiber matrix composites is to do 0 degrees, +45 degrees, -45 degrees, 90 degrees. I'd imagine that this orientation would provide the best overall strength.jimc wrote:well one thing is odd or different and that is you have your infill set at 0 and 90 deg instead of 45 and -45. you would not have that issue when your infill runs diagonally. your parts will be stronger as well. keep random infill placement turned off as well. that bottom gap quite simply doesnt put a line there because it cant fit one.
