What is PLA and why does it continue to lead 3D printing?

PLA, or polylactic acid, is the star filament of 3D printing thanks to its sustainable origin: it is made from renewable resources such as corn, sugarcane, or tapioca 🌽. This material stands out for being easy to use, affordable, and far less toxic than classic ABS, making it the preferred option for those seeking safety and practicality at home.

Did you know that PLA is the most widely used filament in FDM 3D printing worldwide? According to 3Dnatives, it leads the industry thanks to its popularity among makers, businesses, and educational institutions. Its key advantages include being biodegradable under industrial conditions, having low warping, and offering excellent edge definition, ideal for detailed parts.

Let's take a quick comparison:

Feature PLA ABS
Origin Renewable Petroleum-based
Toxicity Low High
Ease of use Very easy Requires experience
Biodegradability Yes (industrial) No

PLA is perfect for rapid prototyping, decorative parts, gadgets, toys, and educational applications, although it has limitations in heat resistance and is not suitable for parts subjected to mechanical stress or high temperatures.

Businesses like Polymaker and BASF are taking PLA printing to another level, developing advanced PLA variants for new industrial and technical applications.

Advantages and disadvantages of PLA in 2025

PLA printing continues to be the favorite among makers and professionals, but why? Let's look in detail at its main advantages and disadvantages, so you can decide whether this filament is the right choice for your projects in 2025.

Advantages and disadvantages of PLA in 2025

Advantages of PLA

  • ♻️ Sustainable: PLA comes from renewable resources and is compostable in industrial environments.
  • Easy to use: You don't need a heated bed or an enclosed 3D printer, making it perfect if you're taking your first steps in PLA printing.
  • Safe: It emits few odors and particles, making it ideal for home or classroom use.
  • 🎨 Variety: There is a huge range of colors and finishes, including hybrids such as wood PLA and matte PLA.
  • Durable: If stored properly (15-25°C, away from moisture), it will last a long time.
  • 🌱 Real example: PolyTerra™ PLA by Polymaker, eco-friendly and supports reforestation.

Disadvantages of PLA

  • ☀️ Heat sensitivity: It deforms easily above 60°C, so avoid using it outdoors or for parts that will be exposed to sunlight.
  • 💪 Limited strength: It is less flexible and strong than other thermoplastics such as ABS or PETG, which limits its use in functional parts.
  • 🌎 Partial biodegradability: Although it is compostable, this only occurs in industrial environments. In nature, it can take decades to break down.
  • 🔨 Brittleness: It breaks under impact and prolonged exposure to UV rays causes damage.
  • 🚗 Example: It is not recommended for automotive parts that must withstand heat or stress.

In summary, PLA printing stands out for being eco-friendly and straightforward, but you need to know its limitations to make the most of it.

Step-by-step guide: How to achieve perfect PLA prints

Ready to become a PLA printing master? Here is a simple and practical guide to take your results to the next level. Follow each step and you'll notice the difference from the very first attempt. Let's go! 🎯

Step-by-step guide: How to achieve perfect PLA prints

1. Choosing the right PLA filament

Start by choosing a quality PLA filament from recognized brands such as Smart Materials 3D or BASF. Consider special options: PLA+, wood, or matte, depending on your project. Check compatibility with your 3D printer and always look for consistency in color.

2. Preparing the 3D printer and calibration

Before printing, thoroughly clean the nozzle and the bed. Calibrate the height and leveling so your first layer comes out perfect. Use adhesives such as hairspray, a glue stick, or special tape to ensure good adhesion.

3. Optimal print settings for PLA

Set the extrusion temperature between 190 and 220°C and the speed between 40 and 60 mm/s. If you use a heated bed, set it between 40 and 60°C. Enable the fan to cool the layers and achieve sharp edges. This way, PLA printing gains quality and precision.

Recommended settings by Prusa and Bambu Lab.

4. Post-processing and final finishing

Sand down any imperfections gently for a professional finish. You can paint your pieces with acrylics or varnishes to protect them and add color. Supports are easy to remove, especially if you use soluble materials.

5. Filament storage and preservation

Store spools in airtight bags with silica gel to prevent moisture. Keep filament between 15 and 25°C and check the expiry date. Moisture causes bubbles and failures in PLA printing, so keep it dry for top results.

Example: Filaments stored in dry boxes in prototyping laboratories.
