I am using flexible filament (ninjaflex) for printing. Recently I have encountered troubles with bonding of outline shells and infill. The print is perfect when completed but the shells are not bonding to each other properly (attached pcitures). I use number of shells of 3 and also tried with 2, but in both cases outline shells are not sticking to each other. I have read in a forum that I need to increase the extrusion multiplier but the printer company I work on asked me not to change it since it is optimized to the extrusion multiplier that they provided. Shells are sticking properly in vertical (layer wise) direction.
I tried reducing the printing speed but no luck yet. Does anyone has experienced the same and found a solution? Thank you.
