PETG

PETG is one of the most versatile 3D printing materials available, sitting perfectly between easy-to-print plastics like PLA and higher-end engineering materials. It’s a popular choice for functional, real-world parts that need strength, durability, and reliability without unnecessary cost.

In this guide, we’ll explain what PETG is, its advantages and limitations, when it’s the right choice, and how PETG is priced at Precision Print Co.

What Is PETG?

PETG (Polyethylene Terephthalate Glycol) is a durable thermoplastic known for its strength, slight flexibility, and chemical resistance. It’s commonly used for functional components that need to withstand everyday use without becoming brittle.

At Precision Print Co, PETG is frequently used for functional parts, enclosures, clips, mounts, and components where PLA would be too brittle but full engineering plastics aren’t required.

Advantages of PETG 3D Printing

PETG offers a strong balance of mechanical performance and practicality.

Strong and Durable

PETG is tougher than PLA and better at handling impact, making it suitable for parts that experience regular use.

Slight Flexibility

Unlike very rigid plastics, PETG has a small amount of flex, which helps prevent cracking under load or vibration.

Good Chemical and Moisture Resistance

PETG performs well in environments where parts may be exposed to moisture, oils, or mild chemicals.

Reliable for Functional Parts

PETG is an excellent choice for parts that need to function reliably over time without complex printing requirements.

Limitations of PETG

While PETG is versatile, it does have some limitations to consider.

Softer Surface Finish

PETG is more prone to surface scratching compared to PLA or PLA-CF.

Less Rigid Than PLA-CF

If a part needs to be extremely stiff with no flex, PETG may not be the best option.

Moderate Heat Resistance

PETG performs better than PLA in warm environments but is not ideal for high-temperature applications.

When Is PETG the Right Choice?

PETG is an excellent option when your project involves:

  • Functional parts and components

  • Clips, brackets, and mounts

  • Enclosures and housings

  • Parts exposed to light moisture

  • Applications needing durability without brittleness

PETG is often chosen when PLA isn’t strong enough, but ABS, ASA, or PA6 would be unnecessary or over-engineered.

PETG Pricing at Precision Print Co

We aim to keep our pricing clear and transparent, especially for functional materials like PETG.

PETG printing at Precision Print Co is priced at:

  • £0.20 per gram of material

  • £2.00 per hour of print time

Final pricing depends on:

  • Part size and weight

  • Print duration

  • Layer height and infill

  • Quantity ordered

If PETG isn’t the best material for your application, we’ll always recommend a more suitable alternative before printing.

PETG vs Other Materials

PETG fills an important gap in material selection:

  • PLA – prototypes and visual parts

  • PLA-CF – rigid structural components

  • PETG – durable functional parts

  • ABS / ASA – heat or outdoor resistance

  • TPU – flexible components

  • PA6 (Nylon 6) – high-strength engineering parts

Choosing PETG often results in a longer-lasting part without unnecessary cost or complexity.

PETG at Precision Print Co

We regularly recommend PETG for customers who need reliable, functional components that will be used day-to-day.

Our focus isn’t just on printing parts — it’s on making sure the material choice matches how the part will actually be used.

That’s what separates a print service from a manufacturing partner.

Need Help Choosing a Material?

If you’re unsure whether PETG is right for your project, we’re happy to help. We’ll review how your part will be used and recommend the most suitable material based on performance, environment, and cost.
