Review on 🖨️ Gizmo Dorks Carbon Fiber Fill Filament 1.75mm 200g: Premium Quality for Flawless 3D Printing by Ahmed Rowe

I needed to stiffen a functional part printed from ASA and came across this thread while looking for a CF nylon spool to buy. I decided to give it a try since it was possible to print at lower temperatures. A number of existing reviews of this product mentioning little or no layer adhesion almost changed my mind, but I ordered it anyway. The part I needed to print required 28g, so this 200g spool would allow me to do lots of tries if I was struggling. The small spool was well packaged and sealed, with a desiccant in the bag. Based on information from some positive reviews I would start my dry run at 235C. Using my FLSUN QQ-S Pro with closed heated chamber with recirculating VOC vapor filter, I first printed two pull tests (with glue stick on PEI layer with 235°C nozzle / 75°C layer / 45°C chamber, line height 3 mm x 6mm). linewidth [for function, not form] at 60mm/s) just to see how it prints and fine tune the settings if needed as this small example only needs 3g/trial. There was 0 stretching and the material was buttery soft. With the exception of temperature, these settings were maintained throughout the process. I then printed a tower at 220-240°C (another minimal size pattern with the same profile except for temperature) to find the best temperature for layer adhesion. The segments broke with a good click so I had decent layer adhesion, but the 240C sample broke multiple layers so that was my GO temp. Adhesion to the film was excellent for both of these samples, even on the bare bed where the main line went down. promising! Printing would have taken a little over 2 hours so I started with trepidation and anticipation. It printed like a charm. I allowed the layer to cool before removing to minimize shrinkage, which also allowed the VOC scrubber to handle outgassing. The sample detached from the bed (in other words without deformation) and the tree supports were easily removed. The part was hard when I tried to bend it with my hands. I was so impressed that I also printed a matching clamp member just to achieve a consistent look, although the ASA piece's greater flexibility for clamping might be more useful. Just take a look. (See image of both parts and their bearings.) Subsequent testing at temperatures up to 260°C showed that the adhesion of the layers continued to improve, however at the highest temperatures the appearance of the part deteriorated significantly in my case. All in all it was a satisfying experience and I would buy again. I wouldn't use it to print everything but it would be nice to buy a full roll. ABS-CF does not smell at all like the ASA I use (PolyMaker and Overture), which was surprising given that their exhaust component, which causes safety issues, is the same (although ABS reported that the exhaust fumes are much larger). . as ACE). ABS-CF smells burnt, possibly of fine charcoal. Given my success with higher print temperatures (and relatively low bed temperatures) and many ABS filaments running up to 280°C, I'm wondering why Gizmo Dorks has a recommended print range of 200-220°C?!?!?
