Complete Guide to 3D Printing Materials: PLA vs ABS vs PETG

Choosing the right 3D printing material is crucial for the success of your project. At 3DreamFactory, our network of Bambu Lab partners works with a wide variety of materials to meet your specific needs. This comprehensive guide will help you understand the key differences between the most popular 3D printing materials.

PLA (Polylactic Acid)

PLA is the most beginner-friendly 3D printing material and the most commonly used filament in the 3D printing community.

Key Properties:

• Ease of Use: Excellent for beginners
• Print Temperature: 190-220°C
• Bed Temperature: 20-60°C (heated bed optional)
• Strength: Moderate
• Flexibility: Low
• Environmental Impact: Biodegradable

Best Applications:

• Prototypes and concept models
• Decorative items
• Educational projects
• Indoor use items
• Detailed miniatures

Pros:

• Easy to print with minimal warping
• Good surface finish
• Biodegradable and eco-friendly
• Wide color selection
• Minimal odor during printing

Cons:

• Lower heat resistance
• Brittle compared to other materials
• Not suitable for outdoor use
• Limited chemical resistance

ABS (Acrylonitrile Butadiene Styrene)

ABS is a strong, durable thermoplastic that's widely used in industrial applications and consumer products.

Key Properties:

• Ease of Use: Moderate (requires experience)
• Print Temperature: 220-250°C
• Bed Temperature: 80-110°C (heated bed required)
• Strength: High
• Flexibility: Moderate
• Environmental Impact: Not biodegradable

Best Applications:

• Functional parts and tools
• Automotive components
• Electronic housings
• Toys and consumer products
• Parts requiring impact resistance

Pros:

• High strength and durability
• Good heat resistance
• Chemical resistant
• Can be post-processed (sanding, drilling, painting)
• Recyclable

Cons:

• Prone to warping
• Requires heated bed
• Strong odor during printing
• More challenging for beginners

PETG (Polyethylene Terephthalate Glycol)

PETG combines the ease of printing of PLA with the strength and durability of ABS.

Key Properties:

• Ease of Use: Good (easier than ABS)
• Print Temperature: 220-250°C
• Bed Temperature: 70-80°C
• Strength: High
• Flexibility: Moderate to High
• Environmental Impact: Recyclable

Best Applications:

• Mechanical parts
• Food-safe containers
• Medical devices
• Transparent parts
• Chemical storage

Pros:

• Strong and durable
• Chemical resistant
• Food safe (when properly printed)
• Good transparency options
• Less warping than ABS

Cons:

• Can be stringy
• Softer surface (prone to scratches)
• Limited high-temperature resistance
• More expensive than PLA
