I have printed frames rails up, rails down, on 45 degree angle, and all seem to have at least one area that is pretty rough looking, usually on the downside of the print. I had a roll of Fiberon PA612-CF and did some reading about supports, "flat" undersurfaces, etc. I found a recommendation for using PETG as a support material because it doesn't "stick" to the nylon carbon fiber. I have a new Bambu H2C, so multinozzle support, and decided to load a file and slice it up. I used a PP_gen35_v1.1 FMDA DD19.2 Gen3.5 frame, textured it in Bump Mesh (free online texture application program - very intuitive and endless textures). I used tree supports on auto, the PA612-CF, and PETG in red for the "support interface" material. I printed it slowly, layer height .15mm, and the 2 nozzles saved swapping - none at all. Here is a pic of it on the print bed. The supports were VERY easy to pop off. The PETG hardly stuck at all, and even with the temp difference in the filaments, it worked pretty well. I used an Xacto blade on a couple of areas. The undersurfaces aren't completely smooth, but I think are better that standard supports. These pics are before annealing and sanding. Overall I'm very impressed with how nice this turned out, but will continue to tweak. Thoughts?
