Which 3D Printing Filament Should You Choose?

Choosing the right filament is one of the most important decisions you’ll make when starting a 3D printing project. At BritForge3D, we work with a wide range of materials daily — but three of the most popular are PLA, PETG, and ABS. Each has unique characteristics that make it ideal for different applications. This guide will help you decide which is right for you.

1. PLA (Polylactic Acid)

Overview: PLA is the most beginner-friendly filament. It’s derived from renewable sources like corn starch and is biodegradable under the right conditions.

Pros:

• Easy to print with – low warping
• Low printing temperature (180–220°C)
• Minimal odour during printing
• Great for detailed, cosmetic prints

Cons:

• Brittle – not ideal for functional parts
• Low heat resistance – softens at 60°C

Best for: Prototypes, toys, models, beginner projects

2. PETG (Polyethylene Terephthalate Glycol)

Overview: PETG strikes a balance between ease of printing and strength. It’s strong, slightly flexible, and more durable than PLA.

Pros:

• High strength and good impact resistance
• Better temperature resistance than PLA
• Water-resistant and food-safe (when printed cleanly)
• Good layer adhesion, minimal shrinkage

Cons:

• Prone to stringing
• Can absorb moisture quickly

Best for: Functional parts, mechanical components, containers, outdoor items

3. ABS (Acrylonitrile Butadiene Styrene)

Overview: ABS is a strong industrial plastic known for its durability. It’s widely used in the automotive and engineering industries but can be trickier to print.

Pros:

What Is 3D Printing?

3D printing, also known as additive manufacturing, is a process where physical objects are created layer-by-layer from digital designs. This contrasts traditional subtractive manufacturing (like carving or milling), where material is removed from a block.

With 3D printing, you can create:

• Prototypes and functional parts
• Artistic models and collectibles
• Medical tools and educational aids
• Customised homeware and gadgets

In short, 3D printing turns digital imagination into real, tangible products quickly and affordably.

Common Types of 3D Printing

There are several different 3D printing technologies, each suited for different applications:

1. FDM (Fused Deposition Modelling)

The most common and beginner-friendly method. A spool of filament (like PLA or PETG) is melted and extruded through a heated nozzle to build an object layer by layer.

2. SLA (Stereolithography)

Uses liquid resin cured by a UV laser. SLA prints offer high detail, often used for jewellery, dentistry, and figurines.

3. SLS (Selective Laser Sintering)

Uses powdered material (usually nylon) fused by a laser. It’s ideal for strong, functional prototypes, often used in industrial settings.

At BritForge3D, we primarily use high-quality FDM and resin systems combining detail, strength, and affordability for UK customers.

One of the most important decisions you’ll make when starting a 3D printing project is choosing the right material. Whether you’re printing a prototype, a mechanical part, or a piece of art, the filament or resin you choose can affect the strength, appearance, and success of your final product.

Why Material Choice Matters in 3D Printing

Every material used in 3D printing has its own set of properties from strength and flexibility to heat resistance and surface finish. Choosing the wrong material can lead to failed prints, brittle parts, or unnecessary expense. Understanding the differences between materials helps ensure you get the best results based on your application.

Overview of Common 3D Printing Materials

• PLA (Polylactic Acid): Easy to print and biodegradable. Ideal for general-purpose prints and prototypes.
• PETG (Polyethylene Terephthalate Glycol): Stronger and more durable than PLA. Great for functional parts.
• ABS (Acrylonitrile Butadiene Styrene): Impact-resistant and heat-tolerant. Used in engineering and manufacturing.
• TPU (Thermoplastic Polyurethane): Flexible and rubber-like. Suitable for phone cases, seals, and wearables.

When to Choose PLA

PLA is perfect for beginners or those creating visual models. It’s affordable, available in a wide range of colours, and prints without warping. However, it’s not the best choice for parts exposed to high heat or mechanical stress.

When to Choose PETG

PETG is ideal for durable parts that need to resist stress or moisture. It offers a good balance between strength and flexibility and is commonly used in mechanical assemblies, tool handles, and enclosures. PETG also has a glossy finish and better UV resistance than PLA.

When to Choose ABS

ABS is known for its high durability and heat resistance. It’s used in automotive components, functional prototypes, and casings. However, it requires a heated print bed and enclosed chamber to prevent warping, and it emits fumes, so good ventilation is essential.

When to Choose TPU or Specialty Filaments

TPU is a flexible filament often used for protective gear, phone cases, and gaskets. Specialty filaments such as carbon fibre, wood-infused, or glow-in-the-dark PLA offer additional features but may require tuning print settings or a hardened nozzle.

Material Comparison Table

Material	Strength	Flexibility	Print Difficulty	Use Case
PLA	Moderate	Low	Easy	Prototypes, models
PETG	High	Moderate	Medium	Functional parts
ABS	High	Low	Difficult	Engineering, industrial
TPU	Moderate	High	Medium	Flexible parts

Tips for Choosing the Right Material

• Match material strength and durability to the intended use
