At Phaser 3D, we’re passionate about unleashing the potential of additive manufacturing and empowering creators like you. This comprehensive guide is designed to introduce you to Polylactic Acid (PLA), a popular choice for both novice and experienced 3D printing enthusiasts. Our aim is to inform you thoroughly about PLA’s properties and characteristics, delve into its common applications, and explore its advantages and limitations, ensuring you can make the most informed decisions for your projects.

 

What are the Properties and Characteristics of PLA?

  • Biodegradability and Eco-Friendliness: PLA is renowned for its environmental benefits, primarily derived from renewable resources like corn starch or sugarcane. Unlike petroleum-based plastics, PLA is biodegradable under the right conditions, breaking down into lactic acid, a naturally occurring substance.
  • Low Melting Temperature: PLA’s low melting temperature (around 150-160°C) makes it particularly user-friendly for 3D printers. This property not only allows for easier printing but also reduces the energy consumption during the printing process, further enhancing its eco-friendly profile.
  • Rigidity and Strength: PLA exhibits a high degree of rigidity and decent strength, which makes it suitable for a wide range of printing applications. However, it’s worth noting that PLA is not as flexible as some other filaments, which can be a limitation for specific uses.
  • Aesthetic Quality: One of PLA’s most appealing characteristics is its ability to produce prints with a high-quality finish. It offers excellent surface qualities, vibrant colours, and a glossier appearance compared to other filaments. These attributes make it ideal for models or parts where aesthetic detail is a priority.
  • Print Bed Adhesion: PLA adheres well to a print bed, which helps in reducing warping issues during the printing process. This makes it a great choice for beginners who might struggle with the intricacies of printing with more temperamental materials.
  • Odour: Unlike some other materials used in 3D printing, PLA does not emit a strong odour during printing, making it more suitable for use in home or educational environments.

By understanding these properties and characteristics, you can better leverage PLA’s capabilities to suit your 3D printing needs.

 

What is PLA Most Commonly Used for in 3D Printing?

PLA is incredibly versatile, making it the filament of choice for a variety of applications across different fields. Here’s a closer look at where PLA really shines:

  • Prototyping and Model Making: Due to its precision and aesthetic qualities, PLA is extensively used for creating detailed models and prototypes, especially in engineering and architecture. Its ability to hold fine details makes it ideal for intricate designs that require a high-quality finish.
  • Educational Projects: Schools and educational institutions favour PLA because it’s safe and easy to use. Its low melting point and lack of toxic fumes provide a perfect setup for classroom environments, where students can experiment with 3D printing without any health risks.
  • Consumer Goods: PLA is widely used for producing consumer goods such as biodegradable cups, utensils, and various household items. Its biodegradability makes it a preferred choice for products that benefit from environmental sustainability.
  • Art and Decoration: Artists and designers often choose PLA for creating art installations, sculptures, and decorative items. Its glossy finish and ability to produce vibrant colours make it suitable for pieces that stand out aesthetically.
  • Medical Sector: In the medical field, PLA has been adopted for creating models for surgical planning and prosthetic devices. Its biocompatibility ensures that it can be used for medical applications without adverse effects.

These applications not only demonstrate PLA’s wide-ranging utility, but also underscore its potential to be customised for specific needs. At Phaser 3D, we leverage the unique properties of PLA to help you achieve the best results, whether it’s a prototype, educational project, or a custom piece of art.

 

What are the Advantages & Limitations of PLA in 3D Printing?

Advantages:

  1. Eco-Friendly: PLA is made from renewable resources, making it one of the most environmentally friendly 3D printing materials available.
  2. Ease of Use: With a lower melting point, PLA is easier to print with, requiring lower temperatures and less energy, which also minimises warping and sticking issues during printing.
  3. Aesthetic Finish: Offers a glossy finish with vibrant colour options, ideal for projects where a high-quality appearance is crucial.
  4. Safety: Emits a mild, non-toxic odour, making it safe for use in schools and homes.

 

Limitations:

  1. Brittleness: While strong, PLA can be brittle, which may limit its use in applications requiring high impact resistance or flexibility.
  2. Heat Resistance: PLA’s lower melting point also means it can deform at temperatures as low as 60°C, making it unsuitable for objects that will be exposed to high temperatures.
  3. Biodegradability Conditions: PLA is biodegradable but only under industrial composting conditions, which are not always readily available.
