The Ultimate Buying Guide for PETG Filament
PETG filament is a fantastic choice for 3D printing. It sits right between PLA and ABS, offering great strength without the tricky printing of ABS. This guide will help you pick the best PETG for your projects.
Key Features to Look For
When you shop for PETG, check these features first. They tell you a lot about how the filament will perform.
1. Durability and Strength
- Look for descriptions mentioning high impact resistance. Strong PETG resists cracking when dropped or bumped.
- Good layer adhesion is key. This means your printed layers stick tightly together, making the final object much stronger.
2. Temperature Resistance
- PETG handles heat better than PLA. Check the glass transition temperature (Tg). Higher numbers mean the print keeps its shape in warmer environments, like a hot car.
- A good Tg for general use is usually around 80°C (176°F).
3. Clarity and Finish (If Needed)
- Clear PETG filaments offer amazing transparency, sometimes rivaling glass.
- Matte or silk finishes can hide layer lines, giving your print a professional look straight off the printer.
Important Materials and Composition
PETG stands for Polyethylene Terephthalate Glycol-modified. Understanding the “G” helps you choose quality.
The Role of Glycol
- The added glycol makes the plastic less brittle than standard PET (like in water bottles).
- This modification also lowers the melting temperature slightly, making it easier to print.
Additives and Colorants
- Most filaments include color pigments. High-quality dyes mix evenly. Poor dyes cause inconsistent color spots.
- Some manufacturers add modifiers to improve bed adhesion or reduce stringing. Read reviews to see if these additives work well.
Factors That Improve or Reduce Quality
The quality of your print depends heavily on the filament quality and how it is stored.
Factors That Improve Quality
- Tight Diameter Tolerance: Good filament has a very consistent diameter (e.g., ±0.02mm). Consistent diameter ensures your extruder pushes out the right amount of plastic every time.
- Proper Spooling: The filament must be wound neatly. Tangled filament causes jams mid-print.
- Good Drying: PETG absorbs moisture from the air easily. Well-dried filament prints smoothly and avoids bubbles or weak spots.
Factors That Reduce Quality (Watch Outs)
- Moisture Absorption: Wet PETG prints poorly. It causes popping sounds in the hotend and weak layer bonds. Always store it in a dry box.
- Inconsistent Diameter: If the filament suddenly gets too thick, the printer nozzle can clog. This stops the print entirely.
- Poor Brand Control: Cheap, unknown brands often have lower quality control, leading to the issues listed above.
User Experience and Use Cases
PETG is known for being somewhat stringy, but modern formulations often fix this. Good user experience means less time spent tuning settings.
Printing Experience
- PETG generally sticks very well to the print bed, sometimes too well! Use a release agent (like glue stick) on glass beds to protect them.
- Printing speeds are usually moderate. Too fast, and you get stringing; too slow, and you might get oozing.
Best Use Cases
- Functional Parts: Use PETG for parts that need to withstand stress or light impacts, like brackets, enclosures, or tools.
- Outdoor Items: Because it handles UV light and moisture better than PLA, PETG is great for garden markers or outdoor sensor housings.
- Food Contact (Use Caution): While the base material is food-safe, 3D printed objects have microscopic layer gaps where bacteria can hide. Use PETG for containers only if you seal the prints thoroughly.
Frequently Asked Questions (FAQ) About PETG Filament
Q: Is PETG harder to print than PLA?
A: Yes, PETG is slightly more challenging than PLA. You usually need higher hotend temperatures (around 230°C to 250°C) and good cooling settings to manage stringing.
Q: Do I need a heated bed for PETG?
A: Absolutely. A heated bed is necessary. Set your bed temperature between 70°C and 90°C. This helps the first layer stick securely.
Q: Why is my PETG printing with lots of strings (stringing)?
A: Stringing happens because PETG oozes slightly when hot. Increase your retraction distance and speed settings on your printer. Also, make sure your filament is dry.
Q: Can I use PETG without an enclosure?
A: Yes, unlike ABS, PETG usually does not require an enclosure. It warps (curls up at the edges) much less than ABS, making it easier for most desktop printers.
Q: Is PETG safe for indoor use?
A: PETG is generally considered safe for indoor use. It releases very few odors or harmful fumes during printing compared to materials like ABS.
Q: How should I store PETG filament?
A: Store PETG in an airtight container with desiccant packs (like silica gel). Keep it away from heat and direct sunlight to prevent moisture absorption.
Q: What is the main difference between PETG and ABS?
A: PETG is easier to print than ABS because it doesn’t warp as much and doesn’t require high enclosure temperatures. However, ABS is often slightly stronger in sheer heat resistance.
Q: Can I paint or finish PETG prints?
A: Yes, you can paint PETG. Lightly sanding the surface first helps the paint stick better. Some specialized primers work very well on PETG surfaces.
Q: What nozzle temperature range should I aim for?
A: Check the manufacturer’s recommendation, but most PETG filaments print best between 235°C and 245°C (455°F to 473°F).
Q: Does PETG stick too well to the print bed?
A: Sometimes, yes. If you print directly onto bare glass or PEI, PETG can bond very strongly. Using a thin layer of glue stick or painter’s tape acts as a release agent, protecting your build surface.
