PLA filaments for 3D printing

Polylactic Acid, more commonly known as PLA, is a thermoplastic made from renewable resources such as corn starch, tapioca roots, or sugarcane. It’s a versatile material extensively used in the 3D printing industry due to its numerous advantages over other types of 3D printing filaments.

PLA is a polymer, which means it consists of large, complex molecules formed by linking together smaller molecules called monomers. The monomers of PLA are lactic acid molecules, which are derived from plant sources. When heated, PLA softens and melts, making it easy to extrude from a 3D printer’s nozzle. When it cools, it quickly solidifies, maintaining the shape dictated by the printer.

Why PLA is Preferred in 3D Printing?

There are several reasons why PLA is the filament of choice for many 3D printing materials:

  • Ease of Printing: PLA’s low melting point (around 180-220°C) and minimal warping make it easy to print with, even for beginners.
  • High Detail Accuracy: PLA can achieve high-resolution prints and capture intricate details.
  • No Noxious Fumes: Unlike ABS and other plastics, PLA does not emit unpleasant or harmful fumes when heated.
  • Eco-Friendly: As a biodegradable material derived from renewable sources, PLA is more environmentally friendly compared to petroleum-based plastics.

PLA Varieties and Grades

There are several types of PLA available, each offering unique attributes. Here’s a table outlining the most common types:

Top Factors to Consider When Choosing PLA Filament

While selecting the best PLA filament for your 3D printing needs, numerous considerations should come into play. Here are some key factors:

1. Quality and Consistency

The consistency of the filament’s diameter is essential. Even slight variations can lead to poor quality prints due to over-extrusion or under-extrusion. Always check the filament’s tolerance – the lower, the better. Also, look for reviews or information about the filament’s quality and consistency over time.

2. Temperature Range

Different PLA filaments might have varying optimal printing temperatures. It’s crucial to consider your 3D printer’s temperature capabilities and ensure it matches with the filament’s printing temperature.

3. Color and Finish

PLA filaments come in a variety of colors and finishes, from basic colors to more unique options like glow-in-the-dark or color-changing filaments. The choice here depends mainly on your personal preference and the visual requirements of the print project.

4. Brand Reputation

Well-established brands often provide high-quality products and are more reliable than lesser-known brands. Look at customer reviews and ratings to gauge the overall satisfaction of previous users.


Storage Tips for PLA Filament

To maintain the quality of your PLA filament, proper storage is crucial. Here are some essential tips:

1. Avoid Moisture

When storing PLA filament, it’s important to avoid moisture. Excessive moisture can cause a number of issues when you’re printing, including clogging and poor layer adhesion. One way to prevent this is to store your filament in a cool, dry place, preferably in a sealed bag with desiccants. Doing so will help keep your filament dry and ready to use when you need it.

2. Temperature Control

While PLA isn’t particularly sensitive to temperature, extreme conditions can degrade the material. This can lead to a range of issues, including warping, uneven extrusion, and poor layer adhesion. To prevent this, it’s important to store your filament in a place where temperature fluctuations are minimal. This could be a climate-controlled room or cabinet, or simply a cool, dry spot in your home or office.

3. Use a Filament Storage Box

For an even higher level of protection, consider using a filament storage box. These boxes provide an optimal environment for filament storage, with desiccants to absorb any moisture and airtight seals to keep out dust and debris. Some even come with built-in temperature controls to ensure that your filament stays at the right temperature at all times. By using a filament storage box, you can help extend the lifespan of your filament and ensure that your prints come out looking their best.


Troubleshooting Common PLA Printing Problems

Even with the best PLA filament, you may encounter issues during printing. Here are some common problems and their solutions:

  • Warping: If your prints are warping or curling at the edges, it could be due to the print bed not being leveled or the initial layer not adhering properly. Use an adhesive on the print bed, ensure the bed is level, and that the initial layer printing speed is slow enough for proper adhesion.
  • Stringing: If you notice thin strings of plastic between parts of your print, it’s often due to retraction settings. Increase the retraction distance and speed in your slicer software.
  • Clogging: If your extruder gets clogged frequently, it might be due to impurities in the filament or the temperature being too low. Ensure your filament is clean and try increasing the extruder temperature slightly.


Summing Up

In conclusion, finding the best PLA filament involves considering several factors such as the filament’s quality, consistency, printing temperature, color and finish options, and the reputation of the manufacturing brand. Careful selection will allow you to have smoother prints, less printing trouble, and ultimately a more satisfying 3D printing experience. Brands like Hatchbox, SUNLU, and Overture provide excellent choices for both general use and specialized applications. Additionally, storing your PLA filament correctly and knowing how to troubleshoot common issues can significantly improve your printing results.

Remember, what works best will depend largely on your specific printing requirements and the capabilities of your 3D printer. Always keep an open mind to try different brands and types of PLA filaments to find what works best for your particular 3D printing projects.



Can I use any brand of PLA filament with my 3D printer?

Most 3D printers can use any brand of PLA filament, provided the filament diameter matches the printer’s specifications (usually 1.75mm or 2.85mm). However, some printers may require specific brands, so always check your printer’s documentation.

How long does PLA filament last?

PLA filament can last for a long time if stored correctly. However, once opened, it’s recommended to use it within six months to a year, as it can absorb moisture from the air, affecting its quality.

Why is my PLA filament breaking?

If your PLA filament is snapping or breaking, it’s likely due to it being too dry. Over time, PLA can lose its flexibility if it’s exposed to low humidity conditions. You can try to restore it by placing the filament in a sealed container with a damp cloth for a day or two.

What temperature should I print PLA at?

PLA typically prints at a lower temperature than other filaments. Most PLA filaments print best between 180 – 220°C, but this can vary depending on the specific brand and color.

Is PLA safe for food?

While PLA is made from food-safe materials, 3D-printed objects may not be food safe due to the small crevices in the print, which can harbor bacteria. It’s not recommended to use 3D-printed PLA objects for storing or serving food unless it’s coated with a food-safe sealant.
