- Is transparent PETG actually clear?
- No. Thin walls and single layers look translucent, but solid parts come out hazy or milky. Getting a clearer look means printing slowly, at the high end of the temperature range, with low or no infill and more perimeters.
- What nozzle and bed temperatures should I use?
- Most PETG prints around 230 to 250 C at the nozzle and 70 to 85 C on the bed. Start in the middle of those ranges, then adjust for stringing and layer adhesion on your printer.
- Does it need a heated bed or enclosure?
- A heated bed helps with first-layer adhesion and warping. An enclosure is not required, but it helps on large parts and in drafty rooms.
- How is it different from PLA?
- PETG is tougher, more flexible and more heat resistant than PLA, but it strings more and prints slower. PLA is easier for detailed models; PETG is better for parts that take stress or warmth.
- How should I store it?
- PETG absorbs moisture, which causes popping and weak layers. Keep the spool sealed with desiccant and dry it before long prints if it has been exposed to humid air.
- What is on the spool?
- One 1 kg spool of 1.75 mm transparent PETG filament, about 2.2 lb.
- Where is the Transparent PETG Filament 1.75mm 1 KG cheapest?
