PLA

PLA is one of the most commonly used 3D printing materials, but it’s often misunderstood. While it’s sometimes seen as a “basic” plastic, PLA still plays a very important role in professional prototyping and low-stress applications when used correctly.

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

What Is PLA?

PLA (Polylactic Acid) is a biodegradable thermoplastic derived from renewable resources such as corn starch or sugarcane. It is widely used in 3D printing thanks to its reliability, clean surface finish, and excellent dimensional accuracy.

At Precision Print Co, PLA is primarily used for prototypes, visual models, and fit-and-form testing, where appearance and accuracy are more important than long-term mechanical strength.

Advantages of PLA 3D Printing

PLA offers several key benefits that make it ideal for specific applications.

Excellent Surface Finish

PLA produces smooth, detailed prints with sharp edges and clean features, making it well suited to visual and presentation parts.

High Dimensional Accuracy

PLA prints with minimal warping, allowing for tight tolerances and accurate fit testing.

Cost-Effective for Prototyping

PLA is one of the most cost-effective materials available, making it ideal for early-stage product development and rapid iteration.

Fast and Reliable Production

Because PLA prints consistently and efficiently, it allows for quick turnaround times and dependable results.

Environmentally Friendlier

PLA is derived from renewable resources and is more environmentally friendly than many petroleum-based plastics.

Limitations of PLA

While PLA is versatile, it is not suitable for every application.

Low Heat Resistance

PLA begins to soften at relatively low temperatures and can deform in warm environments or near heat sources.

Britle Under Impact

PLA is rigid but not tough, meaning it can crack or snap under sudden impacts or repeated stress.

Poor Outdoor Performance

PLA is not UV resistant and does not perform well when exposed to sunlight or weather over extended periods.

Not Suitable for Load-Bearing Parts

For functional components that experience mechanical stress, vibration, or long-term use, stronger materials are recommended.

When Is PLA the Right Choice?

PLA is an excellent option when your project involves:

  • Prototypes and concept models

  • Visual or display parts

  • Fit and form testing

  • Low-stress internal components

  • Cost-sensitive projects

  • Short-term or indoor use

PLA is often used as a first iteration material before moving to PETG, ABS, ASA, TPU, or PA6 once a design is finalised.

PLA Pricing at Precision Print Co

We believe in clear and transparent pricing, so you know exactly what you’re paying for.

PLA printing at Precision Print Co is priced at:

  • £0.13 per gram of material

  • £1.50 per hour of print time

Final pricing depends on factors such as:

  • Part size and weight

  • Print duration

  • Layer height and infill

  • Quantity ordered

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

PLA vs Engineering Materials

PLA should be seen as a starting point, not a limitation.

Typical progression:

  • PLA – early prototypes and testing

  • PLA-CF – rigid structural parts

  • PETG – durable functional components

  • ASA – outdoor and UV-resistant parts

  • TPU – flexible components

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

Choosing the right material at the right stage saves time and cost.

PLA at Precision Print Co

We don’t treat PLA as a “cheap option” — we treat it as the right tool for the job.

If PLA works for your application, we’ll recommend it.
If it doesn’t, we’ll guide you toward a better alternative.

That’s the difference between a print service and a manufacturing partner.

Need Help Choosing a Material?

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