Creality Spool-Free CR RFID PETG 3D Printing Filament 1kg: problems, parts and running costs
Checked: 2026-11-04
Summary
PETG requires drying before printing (60–65°C for 4–6 hours) and proper storage to avoid moisture absorption, stringing, bubbles, and weak layer adhesion. Retraction tuning is needed to minimize oozing. The glossy finish shows layer lines more than matte finishes. The RFID chip requires Creality’s Filament System (CFS) to work. Warranty is up to 12 months.
Common problems and fixes
- Moisture absorption — causes stringing, bubbles, weak layer adhesion. Fix: dry filament at 60–65°C for 4–6 hours before printing and store in sealed bags or dry boxes with desiccant. [1]
- Stringing behavior — PETG is more prone to stringing than PLA or ABS. Fix: adjust retraction settings and printer calibration. [1]
- Bed adhesion issues — parts may not stick to the build plate. Fix: use glue sticks or a heated bed. [1]
- Surface roughness — glossy prints show layer lines and imperfections. Fix: adjust print settings or choose matte finish for better appearance. [1]
- Heat resistance limits — PETG has good heat resistance (~75°C) but not as high as ABS or ASA (~100°C). For parts exposed to temperatures above 80°C, ABS or ASA may be more appropriate. [1][2]
