PETG vs ABS: Which Filament Should You Use?
Introduction: The Battle of High-Strength Filaments
When it comes to creating durable and functional 3D printed parts, PLA often doesn’t make the cut. That’s where PETG and ABS step in—two popular filaments known for their strength, temperature resistance, and reliability. However, each comes with its own unique properties, pros, and challenges.
In this detailed comparison, we’ll explore everything you need to know about PETG vs ABS—from print quality and strength to ease of use and practical applications. By the end, you’ll know exactly which filament fits your project and printer setup best, especially if you’re working in India’s varying climates and conditions.
What Is ABS Filament?
ABS (Acrylonitrile Butadiene Styrene) is one of the oldest and most industrially used 3D printing materials. Known for its strength and impact resistance, ABS is preferred for automotive parts, tools, and enclosures.
Key Characteristics of ABS:
- High impact and temperature resistance
- Requires a heated bed (90–110°C)
- Emits strong fumes—needs proper ventilation
- Can warp without an enclosed printer
Real-Life Example:
A Pune-based robotics startup uses ABS to manufacture sensor housings and structural parts due to its strength and machinability after printing.

What Is PETG Filament?
PETG (Polyethene Terephthalate Glycol) is a glycol-modified version of the same plastic used in water bottles. It combines the strength of ABS and the ease of printing like PLA, making it one of the most versatile filaments in the market today.
Key Characteristics of PETG:
- Strong, flexible, and weather-resistant
- Requires moderate heat bed (70–80°C)
- Minimal warping, even in open-frame printers
- Low odour, easy to print
Real-Life Example:
A Delhi-based product designer prints PETG enclosures for IoT devices because it resists humidity and UV exposure, making it perfect for outdoor use.

PETG vs ABS: Feature-by-Feature Comparison
1. Printability
- PETG is easier to print than ABS and works well even without an enclosure.
- ABS requires strict temperature control and enclosure to avoid warping and cracking.
Verdict: PETG is better for beginners and general users.
2. Strength and Durability
- ABS has superior tensile strength and toughness, especially under impact.
- PETG has excellent flexibility and fatigue resistance, but may tear under high impact.
Verdict: Use ABS for load-bearing or impact-resistant parts; PETG for flexible strength and chemical resistance.
3. Heat Resistance
- ABS can withstand up to 100°C or more.
- PETG softens around 80°C.
Verdict: ABS is the clear winner for high-heat environments.
4. Surface Finish
- PETG prints glossy, transparent or semi-matte, depending on settings.
- ABS gives a matte finish and can be post-processed with acetone for a smooth surface.
Verdict: ABS allows better post-processing; PETG offers cleaner prints without post-work.
5. Fumes and Safety
- ABS emits strong fumes that can irritate eyes and lungs—ventilation is mandatory.
- PETG produces very little odour, safe to use in indoor settings.
Verdict: PETG is safer for home and office use.
6. Price and Availability in India
- PETG is slightly more expensive than PLA but increasingly common.
- ABS is affordable, but best used only if you have an enclosed printer setup.
Top Indian Suppliers:
- PETG: WOL3D, Esun, Creality, 3idea
- ABS: WOL3D, AURUM, Sunlu, Protoprint

Which Filament Should You Use?
Use PETG If:
- You want durable parts with some flexibility
- You’re printing in open or semi-open environments
- You’re building weather-resistant or chemically exposed components
- You are a beginner moving beyond PLA
Use ABS If:
- You need maximum strength and heat resistance
- You have a fully enclosed 3D printer
- You can post-process parts for aesthetic or strength improvement
- You’re printing functional, mechanical or automotive parts

Industry Use Cases in India
1. PETG in Electronics
Startups building outdoor electronics and sensor units often prefer PETG due to its resistance to moisture and UV light. In Bangalore, smart irrigation systems use PETG housings for outdoor deployment.
2. ABS in Automotive & Prototyping
Automotive garages in Haryana and Punjab prefer ABS for printing car dashboard mounts and engine bay parts due to its heat tolerance and structural strength.

Tips for Printing PETG and ABS Successfully
For PETG:
- Use a glue stick or painter’s tape for better bed adhesion
- Dry the filament before use; PETG absorbs moisture
- Avoid excessive retraction to reduce stringing
For ABS:
- Use an enclosure to maintain ambient temperature
- Always ventilate the print area
- Try acetone vapour smoothing for a polished look

Final Thoughts
PETG vs ABS is not a question of which is better, but which is better for you. If you’re just entering functional 3D printing, PETG gives you strength and ease in one package. If you’re confident in your machine and need industrial-grade toughness, ABS won’t disappoint, provided you can manage its strict printing conditions.
For Indian users, where temperature and ventilation can be challenging, PETG is often the safer and more versatile choice. That said, ABS still rules when it comes to heat resistance and strength, especially in professional-grade applications.
