As cooling is an important part of 3D printing I was wondering what effect the direction air flow would cause on a print finish. The short test today is between the SN04 and the Tevo Tarantula Fang.
Both can be found on thingiverse here and here
Now don't get me wrong the SN04 is a great fan duct. I've been getting some awesome results from using it i just found it a pain when setting up my webcam it would get in the way and i wouldn't be able to see the layers.
After fitting the Fang duct before doing a the test print I turned on the fan to see if it was pushing enough air through and I wasn't really too impressed with it. The ends seem a bit too far from the hotend which means that air isn't being directed sharply enough.
So the results are in! and I'm actually surprised which on I think win's. The test print was a 20mm calibration cube which was scaled down by half. It has single wall thickness and 5% infil at 65mm/s. Unfortunately I got some layer shifting on the end of the last print as you'll see in the images below. The definition of the letters are clearly better with the SN04. There for I declare it the winner. I think as it has won I'm going to print a new one in the better PLA as it was one of the first things I printed and didn't really know what settings did what.
The images below SN04 is on the Left and the Tevo Tarantula Fang is on the Right. (Yes I know the print isn't perfect on any of them but it was just a quick test)
Let me know your thoughts on it, do you prefer the Fang over the SN04 or are you using a completely different one?
