PLA-CF

PLA-CF (Carbon Fibre Reinforced PLA) is a step up from standard PLA, offering increased stiffness, reduced flex, and a professional finish. It’s ideal for parts that need to be rigid, dimensionally stable, and cleanly presented, without moving into full engineering plastics.

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

What Is PLA-CF?

PLA-CF is a composite material made by reinforcing standard PLA with chopped carbon fibre. The carbon fibres increase stiffness and reduce flex, resulting in parts that feel more solid, stable, and professional compared to regular PLA.

At Precision Print Co, PLA-CF is commonly used for rigid brackets, jigs, fixtures, mounts, and structural components where stiffness and appearance matter more than impact resistance.

Advantages of PLA-CF 3D Printing

PLA-CF offers several benefits over standard PLA.

Increased Stiffness

The added carbon fibre significantly reduces flex, making PLA-CF ideal for rigid structural parts.

Excellent Dimensional Stability

PLA-CF prints with minimal warping, helping maintain tight tolerances and consistent dimensions.

Professional Matte Finish

PLA-CF produces a clean, matte surface that hides layer lines better than standard PLA, giving parts a premium appearance.

Lightweight Yet Solid

Despite its rigidity, PLA-CF remains lightweight, making it suitable for applications where weight matters.

Limitations of PLA-CF

PLA-CF is not a universal solution and has some important limitations.

Limited Heat Resistance

Although stiffer than PLA, PLA-CF shares similar heat resistance limitations and is not suitable for high-temperature environments.

Brittle Under Impact

PLA-CF is designed for rigidity, not toughness. It can crack under sudden impact or repeated shock loading.

Not Suitable for Flexible or Load-Cycling Parts

Parts that need to flex, absorb vibration, or handle repeated stress cycles are better suited to PETG, TPU, or PA6.

When Is PLA-CF the Right Choice?

PLA-CF is an excellent option when your project requires:

  • Rigid brackets and mounts

  • Jigs and fixtures

  • Structural components with minimal flex

  • Parts where appearance and stiffness matter

  • Lightweight components with a premium finish

PLA-CF is often chosen when PLA is too flexible, but full engineering materials like PA6 would be unnecessary.

PLA-CF Pricing at Precision Print Co

We believe in clear and transparent pricing, especially for materials used in professional and functional applications.

PLA-CF 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 PLA-CF is not suitable for your application, we’ll always recommend a more appropriate material before printing.

PLA-CF vs Other Materials

PLA-CF fits into our material lineup as follows:

  • 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 PLA-CF is ideal when stiffness and finish are priorities, but extreme durability is not required.

PLA-CF at Precision Print Co

We regularly recommend PLA-CF for customers who need rigid, professional-looking parts that hold their shape and perform consistently.

Our focus is always on choosing the right material for the job, not just the most expensive or over-engineered option.

That’s what makes us a manufacturing partner, not just a print service.

Need Help Choosing a Material?

If you’re unsure whether PLA-CF 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.
