Improper barrel temperature setting of PLA '2079851475616104452 causing degradation
ظاهرة المشكلة
The barrel temperature is too high, causing PLA degradation and yellowing.
تحليل الأسباب
PLA has poor thermal stability; the temperature of each section is set too high, and it degrades rapidly above 200-220°C.
الحل
Set according to a decreasing curve: rear section 160-170°C, middle section 175-185°C, front section 180-190°C.
الخلاصة الأساسية
The PLA barrel temperature setting should be conservative.
