PETG 3D PRINTING: THE EXPERT’S GUIDE TO STRONG, RELIABLE AND PROFESSIONAL PRINTS

Written By Morgane Krauss

Discover why PETG is the go-to filament for strong, durable and reliable 3D prints. Expert tips, print settings and insider tricks from Colorful®.

If you’ve only tried PLA or ABS, you’re missing out. PETG filament combines the best of both words: strength, flexibility and ease of printing, making it a top choice for professionals and hobbyists alike. At Colorful®, we’ve tested, tuned and mastered PETG to help you create flawless prints every time. 

What is PETG and why it stands out

PETG (Polyethylene Terephthalate Glycol) is a thermoplastic that’s engineered for performance. Unlike PLA, it can withstand stress, heat, and outdoor use. Compared to ABS, it’s easier to print with and less prone to warping.


Key Advantages of PETG:

Strength & Durability — perfect for functional parts

  • Flexibility — resists cracking under stress

  • Heat Resistance — survives higher temperatures

  • Clarity & Finish — glossy, transparent options available

  • Outdoor-Ready — UV and impact resistant

PETG vs. PLA

Expert tips for printing with PETG

As PETG experts, we’ve gathered the most important print settings and tricks you need:

  • Nozzle Temperature: 235–250°C → PETG loves higher heat

  • Bed Temperature: 70–85°C for better adhesion

  • Cooling Fan: Low (20–40%) → too much airflow causes weak layers

  • Adhesion Tip: Use a light glue stick—not for sticking, but for easy release

  • Retraction: Increase slightly compared to PLA to prevent stringing

💡 Pro Tip: PETG is slightly “sticky,” so keeping your nozzle clean helps prevent blobs.
