Topic: abs melting point

Just curious why we use  such a high hotend temp when  the melting point of ABS is 105 C


221°F (105°C)
Acrylonitrile butadiene styrene, Melting point

SD3, E3D hotend,linear bearing on x/y axis',pillow block bearing on y conneting rod, ball bearngs on front y axis, fan on y stepper motor.

The *glass transition temperature* is 105C. That's the temperature it begins to soften. It is amorphous, and therefore has no true melting point.

Re: abs melting point

From my experience, not all ABS is the same so you really cant use exact numbers to have exact results. Plus, the environment makes a big defference in your settings as well. Best thing to do is test for yourself and go with what works best for you.
