Overview of PLA Filament

If you’re diving into the world of 3D printing, PLA filament is likely one of the first terms you’ll come across. PLA, or Polylactic Acid, is a popular filament choice among 3D printing enthusiasts. Let’s explore what makes it special and why it’s worth considering for your printing projects.

Advantages and Disadvantages of PLA

Like any material, PLA filament comes with its own set of advantages and disadvantages. It’s important to weigh these factors when deciding if PLA is the right choice for your specific needs. Read here technical properties in wikipedia


  • Ease of use: PLA is known for its user-friendly nature, making it ideal for beginners.
  • Environmental friendliness: PLA is derived from renewable resources, making it a more sustainable option.
  • Low warping: PLA has minimal warping tendencies, ensuring better print quality and less frustration during the printing process.
  • Dimensional accuracy: PLA offers excellent dimensional accuracy, helping you achieve precise and accurate prints.
  • Smooth surface finish: PLA filament produces prints with a smooth surface, perfect for aesthetic purposes.


  • Limited heat resistance: PLA has a lower heat tolerance compared to some other filaments, limiting its use in high-temperature applications.
  • Lower strength: While PLA is durable for many applications, it may not be suitable for heavy stress or load-bearing parts.
  • Biodegradability: While it’s environmentally friendly, PLA’s biodegradability can be a disadvantage if you require long-lasting or weather-resistant prints.

PLA Filament Properties

Understanding the properties of PLA filament is crucial for achieving successful 3D prints. Here are some key properties to keep in mind:

  • Melting temperature: PLA has a relatively low melting temperature, typically ranging from 180°C to 220°C, making it compatible with a wide range of 3D printers.
  • Print bed temperature: PLA generally does not require a heated print bed but benefits from a slightly warm (around 50-60°C) bed for better adhesion.
  • Printability: PLA has excellent printability, with minimal warping and good layer adhesion, resulting in smoother prints.
  • Strength and stiffness: While PLA is not the strongest filament, it offers decent strength and stiffness for many applications.
  • Biocompatibility: PLA is biocompatible, making it suitable for certain medical and food-related applications.
  • Post-processing: PLA is easy to post-process, allowing for sanding, painting, or gluing if desired.

PLA Filament Uses and Applications

PLA filament finds applications in various industries and creative endeavors. Here are some popular uses and applications:

  • Prototyping: PLA is commonly used for creating prototypes, allowing designers to iterate and refine their designs before production.
  • Models and figurines: The smooth surface finish and vibrant colors of PLA make it a popular choice for creating models, figurines, and artistic sculptures.
  • Educational purposes: PLA is widely used in educational settings to bring concepts to life with tangible, 3D-printed models.
  • Decorative and functional prints: PLA’s aesthetic appeal and ease of printing make it ideal for creating decorative objects, customized phone cases, and practical household items.
  • Cosplay and props: PLA’s lightweight nature, coupled with its ease of post-processing, makes it a favorite for cosplay enthusiasts and prop makers.

PLA Filament Brands and Manufacturers

Several reputable brands and manufacturers produce high-quality PLA filaments. Here are a few well-known names in the industry:

  • eSun: eSun offers a range of PLA filaments known for their reliability and vibrant color selection.
  • Hatchbox: Hatchbox PLA filaments are popular among 3D printing enthusiasts due to their consistent quality and affordability.
  • Polymaker: Polymaker is known for its advanced PLA filaments, including its unique PolyMax PLA, which offers enhanced strength and heat resistance.
  • ColorFabb: ColorFabb produces high-quality PLA filaments with a focus on vibrant colors and consistent printing performance.
