@Dim3nsioneer : here is the guy of bioFila ;-)
1.) What do you mean by "once-extruder-never-gets-weak-again"?
2.) The softening temperature (Erweichungstemperatur) of bioFila is 58.4°C (VST = Vicat Softening Temperture)
see MDS on our homepage: http://www.two-bears.eu/media/MDBbiofilasilkR3.pdf
We use 55°C as temperature for the hotbed and it works perfect.
