Why they like 3mm filament:
3mm is more rigid than 1.75mm.
3mm is less expensive than 1.75mm to manufacture.
3mm doesn’t have to be made to as tight of a tolerance as 1.75mm (or is more tolerant–a difference in diameter in 1.75mm is reflected more in the print).
3mm can feed better with a wider variety of extruders.
3mm won’t snap as easily as 1.75mm, which is important for brittle filaments (like Laywood or something).
3mm won’t crush as easily as 1.75mm (for a filament like HIPS).
3mm can feed a greater amount of plastic faster than 1.75mm, if you are printing fast.
1.75mm tangles a lot easier than 3mm.
Make Magazine rated the TAZ and UM2 as top performers, both use 3mm. Just sayin’.
LulzBot Edition of Cura Profiles:
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
