This solved a stopping problem that I had with a 3D printed clock I was building. The printed parts have that extra lubricity that made a huge difference in the most delicate parts of the clock where forces are low and friction matters.
I was recommending the filament to the clock’s designer: www.stevesclocks.com, and he asked me a great question: is this filament safe to print indoors without ventilation. I have no idea. I printed it without any noticeable odor, but I can’ rule out microparticles of PTFE being released.
Printing with PETG filament typically produces fewer fumes than materials like ABS, but it can still emit some particles and odors. While PETG is considered safer for indoor printing, good ventilation is recommended to minimize exposure to any potential emissions and keep the air quality at a comfortable level.
PTFE itself is usually stable at the temperatures used for 3D printing with common filaments like PLA or PETG. However, if heated beyond its decomposition temperature (around 260°C or 500°F), PTFE can release harmful fumes. It’s important to avoid overheating your filament and keep the printing temperature within the recommended range.
