Materials Explained – PLA vs ABS (Which One Should You Use?)

Introduction

Choosing the right material is crucial to getting a great 3D print. PLA and ABS are the two most popular plastics—but they’re suited to different needs. Let’s break it down.

🧪 1. PLA – Polylactic Acid

Pros:

• Easy to print
• Biodegradable & eco-friendly
• Great for toys, display items, and low-stress parts
  Cons:
• Not very heat-resistant
• Brittle under pressure

Use PLA when:
You need something lightweight, colorful, and not exposed to heat—like toys, decor, or prototypes.

🔥 2. ABS – Acrylonitrile Butadiene Styrene

Pros:

• Tough & durable
• Better heat resistance
• Ideal for mechanical parts
  Cons:
• Emits fumes (needs ventilation)
• Prone to warping during print

Use ABS when:
You need stronger, long-lasting parts like gears, enclosures, or anything exposed to sunlight and stress.
