I love the ASA-CF08. Aside from having one bad batch, it has always printed very well for me and the 8% Carbon Fiber is a perfect catalyst for ASA to stabilize it. Literally ALL of the problems that people experience with standard ASA are eradicated with the CF08 variant. It doesn’t warp, it doesn’t peel off the bed, it doesn’t lose layer adhesion, it doesn’t have bed adhesion issues, it doesn’t have cooling issues with bridges, it just prints beautifully every single time. And if you use the fan at 100% for both support interface layers and supported bridges, you can have a tiny air gap of 0.05mm and the supports will literally pop off after the print, leaving a PERFECT bottom layer that is nearly as clean as the bed layer itself! You do have to tune the bridge settings and have a bit more flow rate, have the speeds, acceleration, and jerk settings correct, but a few tests will reveal the optimum settings. I am using a 1.5625 flow multiplier with 100% overlap, 500mm/^2 accel, and 1mm/s jerk for bridges to achieve incredible results. I absolutely love this filament and I am considering dropping standard ASA from my filament list entirely to use this only because of how awesome it prints. And I haven’t even mentioned the surface finish which is downright ****! With 0.1mm layers, the layer lines entirely disappear and you are left with an amazing final finish that requires absolutely zero post-print finishing required other than maybe paint. Just be aware that there may be a few cases of a bad batch where some oversize chunks of carbon fiber or excessive quantities may be present which can clog a 0.4mm nozzle from time to time. It’s kind of a pain to clear because you have to remove the nozzle and heat it by other means to dig clean out the nozzle and clear it as using a standard clearing pin will simply push the chunk or whatever to the side and not actually clear the clog, leading to an immediate re-clog. But that occasional issue is worth the rest of the benefits of this filament. It also produces amazing strength, especially if you raise the number of walls to 5 or 6. I have printed truly structural parts with this filament and it holds up perfectly. Awesome filament! Get yourself a good hybrid nozzle such as a MicroSwiss CM2 or something of that nature and prepare to be amazed!
