What is PLA? Everything About This Sustainable and Biodegradable Material

You increasingly hear the term PLA, especially when it comes to sustainable plastics and 3D printing. But what exactly is PLA, and why is it considered an eco-friendly alternative to traditional plastics?

PLA, or polylactic acid (Polylactic Acid), is a biodegradable plastic made from natural materials such as cornstarch or sugarcane. This makes it a popular material for sustainable packaging, 3D-printed products, and even fidget toys.

What is PLA? The Basics

PLA is a biodegradable plastic produced from renewable resources. Unlike traditional plastics made from petroleum, PLA is derived from plant-based materials such as cornstarch, sugarcane, or cassava starch.

The production process of PLA involves the following steps:

1. Extraction of sugars – Cornstarch or sugarcane is broken down into simple sugars.
2. Fermentation – These sugars are fermented into lactic acid, a naturally occurring substance.
3. Polymerization – The lactic acid is then converted into polylactic acid, or PLA.

Since PLA is not derived from fossil fuels, its production has a lower CO₂ footprint compared to conventional plastics like ABS or PET. This makes it a much more sustainable alternative.

Why Choose PLA? The Benefits

PLA offers several major advantages compared to traditional plastics:

Sustainable and Biodegradable

PLA decomposes under the right conditions and is industrially compostable, meaning it does not contribute to long-term plastic pollution like other plastics.

Non-Toxic and Safe

Because PLA is made from natural materials, it is not harmful to humans or the environment. This makes it perfect for food packaging, toys, and 3D-printed gadgets.

Easy to Process

PLA is one of the easiest plastics to 3D print, as it melts at relatively low temperatures and does not emit harmful fumes.

Lightweight and Strong

PLA is lightweight yet sturdy, making it a versatile material for various applications, from packaging to mechanical components.

Thanks to these benefits, PLA is increasingly being used as an eco-friendly alternative in different industries.

PLA vs. Other Plastics

How does PLA compare to other commonly used plastics?

PLA vs. ABS

• PLA: Biodegradable, odorless when 3D printing, easier to print.
• ABS: Stronger and more heat-resistant but not environmentally friendly and releases toxic fumes when heated.

PLA vs. PETG

• PLA: Eco-friendly, easier to print, but less flexible.
• PETG: Stronger and more flexible than PLA but harder to degrade.

PLA vs. Traditional Plastic (such as PVC or PE)

• PLA: Renewable resources, compostable, and less harmful to the environment.
• PVC/PE: Made from fossil fuels, non-biodegradable, and contributes to plastic pollution.

Although PLA is not suitable for all applications (for example, it melts relatively quickly at high temperatures), it is an excellent alternative to conventional plastics in many cases.

PLA and 3D Printing: Why Is It So Popular?

PLA is the most commonly used material for 3D printing, and for good reason. Both beginners and experienced makers often choose PLA because of its ease of use, sustainability, and safety.

Advantages of PLA in 3D Printing:

• Low printing temperature → PLA melts at around 180-220°C, making it easy to print without a heated print bed.
• Minimal odor or fumes → Unlike ABS, which can release harmful fumes, PLA is odorless and safe for home use.
• High print quality → PLA produces sharp details and a smooth surface, ideal for decorative objects, prototypes, and premium fidget toys.
• Biodegradable → PLA waste is less harmful to the environment than other plastics.

Because PLA is so versatile and eco-friendly, it is increasingly used for personalized 3D-printed products, such as fidget toys, phone stands, and design objects.

Is PLA Really Biodegradable?

One of PLA’s biggest advantages is that it is biodegradable, but how does that actually work?

PLA and Composting:

PLA decomposes under specific conditions, mainly in industrial composting facilities, where it is exposed to:

• High temperatures (+60°C)
• High humidity
• Microorganisms that accelerate the decomposition process

PLA and Home Composting:

Although PLA is biodegradable, it does not break down easily in nature or in a regular compost bin. It can take years for PLA to fully degrade in natural conditions.
