Human: Carbon Skeleton or 3D Component Carbon Fiber is a technique where you print only the mounting components of your part. Components are fixed in a proper fixing structure and connected with carbon fiber tow. You will create lightweight and rigid carbon fiber parts made by real continuous carbon fiber tow. All details, including test results, can be found in my Instructables tutorial below. Printer Settings: Brand: Ultimaker Printer: Ultimaker 2 Rafts: No Supports: No Infill: 100% Material: ColorFabb - XT-CF20 Post-Printing: 1. Fix parts in a fixing structure. 2. Insert 1x3mm carbon profiles. 3. Insert mounting points, using 1,2mm carbon rods to wire carbon around (see picture from another part). 4. Wire tow all around the part, epoxying all fibers every 2-6 turns. Wait for epoxy to cure and sand excess material. 5. Cut excess, sand, and use. Troubleshoot: I had a few problems with my final part. I had to remove two carbon fiber bridges to be able to mount it. Additionally, due to the design of the 3D printed shock, the clearance with added carbon fiber was too high, so the arm was unable to move in its full range. Prepare some winding ideas before starting with chaotic winding like me to avoid these problems. How I Designed This: 1. Recreate mounting components of your part. 2. Remove the original part. 3. Expand it for mounting points and grooves for carbon tow. 4. Create a mounting fixture (print it twice). 5. Send to your slicer. Custom Section: The total weight is higher than the ABS part, but strength is much more significant. Check out my carbon quadcopter arms done using this method in my profile for bend tests. Sorry for the forgotten screw - the ABS part had bug problems between layers for such thin and tall parts to print, making it break easily.
