Road to a fanless printhead - DIY radial blower cooling

Chopmeister's 3D Printing Stuff

You need a fan to print with PLA. I love PLA. I hate fan mounts. Fans are bulky and can potentially mess up your thermocouple readings (due to interference from the fan wires). I am a fan of fans in general, but not on a printhead.

3D printing with cheap Nylon trimmer line/string


Is filament quality so important after all? I heard years ago that trimming line was one of the many materials that was tested on a 3D printer (the biggest list is probably here ). This time I tried for myself, and it was also the proper occasion to deal with how "reliable" the material has to be.
