Exploring PLA Filament: Best Uses, Advantages, and Disadvantages

Polylactic Acid (PLA) filament is a cornerstone material in the world of 3D printing, cherished for its user-friendliness and versatility. Whether you're a seasoned professional or a newcomer to 3D printing, understanding the ins and outs of PLA filament can significantly enhance your 3D printing experience. In this post, we will explore the best uses for PLA, its advantages and disadvantages.


The Best Uses for PLA Filament


PLA filament is highly versatile, making it suitable for a wide range of applications:


  • Prototyping: Due to its low cost and ease of use, PLA is ideal for creating prototypes. Designers can quickly print and test their ideas without a significant financial burden.

  • Decorative Items: PLA's smooth finish and variety of colours make it perfect for creating aesthetically pleasing objects, such as vases, figurines, and decorative art.

  • Educational Purposes: PLA’s non-toxic nature and straightforward printing process make it an excellent choice for educational settings. Students can safely learn the basics of 3D printing and material properties.

  • Art Projects: Artists use PLA to bring digital models to life. Its availability in various colours and finishes allows for creative and detailed artworks.

  • Cosplay and Props: PLA is popular in the cosplay community for making detailed costumes and props. Its ease of painting and finishing helps achieve a high level of detail and realism.


Advantages of PLA Filament


  • Ease of Use: PLA is one of the easiest filaments to print with, requiring lower printing temperatures and adhering well to the print bed, which reduces the risk of warping.

  • Environmentally Friendly*: Made from renewable resources like corn starch and sugarcane, PLA is biodegradable, making it a more eco-friendly option compared to petroleum-based filaments.

  • Minimal Odour: Unlike some other filaments, PLA emits minimal odour when printing, making it more pleasant to use, especially in enclosed spaces.

  • Variety of Colours and Finishes: PLA comes in a wide range of colours and finishes, including transparent, metallic, and glow-in-the-dark, offering flexibility for creative projects.


Disadvantages of PLA Filament


  • Low Heat Resistance: PLA has a lower melting point compared to other filaments such as ABS. It can deform when exposed to temperatures around 60°C, limiting its use in high-temperature applications.

  • Brittle Nature: While PLA is strong, it is relatively brittle and can break under stress or impact. It is not suitable for parts that require flexibility or are subject to significant mechanical stress.

  • Limited Durability: PLA is biodegradable, which means it may degrade over time, especially when exposed to moisture and sunlight. This can limit its lifespan in certain applications.


PLA filament remains a top choice in the 3D printing community due to its ease of use, vibrant colours, and environmentally friendly properties. It is well-suited for prototyping, educational purposes, decorative items, art projects, and cosplay. While it does have limitations, such as low heat resistance and brittleness, its advantages often outweigh these drawbacks.


By understanding the best uses, advantages, and disadvantages of PLA filament, you can make informed decisions about your 3D printing projects, ensuring successful and satisfying results. Whether you are a beginner or an experienced 3D printing enthusiast, PLA filament offers a reliable and versatile material to bring your ideas to life.
