One of the most common materials that are used when it comes to 3D printing includes Polylactic Acid (PLA) filament, which is easily accepted by both amateurs and experts alike since it is environmental-friendly and no skill is required to use it. Pla is biodegradable due to renewable resources such as corn starch or sugarcane, which in turn makes it an environmentally friendly choice to the traditional petroleum-based plastics. This is the article where we will dwell on what PLA filament is, the benefits, and the downsides of using it and how to find the proper PLA filament to run your 3D printing activities.
So what is PLA filament?
PLA Filament refers to a type of thermoplastic polymer that is widely applied in the Fused Deposition Modeling (FDM) 3D printers. It is polymerized to lactic acid that is fermented using plant sugars. This gives a material that is biodegradable and has a low level of toxicity hence safe to use in indoors or learning settings.
Benefits of PLA Filament
Convenient to use: PLA is easier to use because the melting point is relatively low, about 180-220 o C, and no heated bed is required when printing. The feature renders it suitable to amateurs and novice users.
Reduced warping: PLA has a low shrinkage rate than other materials such as ABS, and therefore, warping is minimized, and the accuracy/consistency of printing is improved.
Environmental Advantage: PLA is a more environmentally friendly alternative to 3D printing than conventional plastics as it is made of renewable sources it is a biodegradable plastic that is more eco-friendly and requires less dependence on fossils sources.
Accessibility: PLA filament has very wide availability due to the fact that it is commonly made in many colors and finishes including matte, glossy and even unusual qualities such as silky PLA which provides a shiny, reflective finish.
Disadvantages of PLA Filament
Low Heat Resistance: PLA has a relatively low glass transition temperature (around 60°C), meaning it can deform under heat. This makes it unsuitable for applications involving high temperatures, such as automotive parts or outdoor fixtures exposed to direct sunlight.
Brittleness: While PLA is rigid, it can be more brittle than other materials like ABS or PETG, making it less suitable for parts that require flexibility or impact resistance.
Moisture Sensitivity: PLA filament can absorb moisture from the air, leading to issues like bubbling or stringing during printing. It's essential to store PLA in a dry environment to maintain its quality.
How to Choose the Right PLA Filament
When selecting PLA filament for your 3D printing projects, consider the following factors:
Diameter Consistency: Ensure the filament has a consistent diameter (commonly 1.75mm or 3mm) to prevent clogging and ensure smooth extrusion.
Color and Finish: Choose a color and finish that suits your project needs. Specialty PLA filaments, like silk PLA, can add a unique aesthetic to your prints.
Brand Reputation: Opt for reputable brands known for producing high-quality PLA filament to ensure reliability and consistency in your prints.
Storage Conditions: Store PLA filament in a cool, dry place to prevent moisture absorption and maintain print quality.
Applications of PLA Filament
PLA filament is versatile and can be used in various applications, including:
Prototyping: Ideal for creating prototypes due to its ease of use and quick print times
Educational Models: Safe and non-toxic, making it suitable for educational environments to create models and teaching aids.
Art and Design: With a wide range of colors and finishes, PLA is popular among artists and designers for creating sculptures and decorative items.
Home Decor: PLA's aesthetic appeal makes it a popular choice for creating custom home decor items like vases, planters, and figurines.
Conclusion
PLA filament stands out as a user-friendly, environmentally conscious material in the world of 3D printing. Its ease of use, minimal warping, and biodegradability make it an excellent choice for a wide range of applications, from prototyping to art and design. By understanding its properties and limitations, you can make informed decisions and achieve high-quality results in your 3D printing projects.
