Understanding Biodegradable Filaments: PLA and Its Eco-Friendly Companions
As 3D printing technology continues to evolve, the demand for sustainable materials is on the rise. Biodegradable filaments like PLA (polylactic acid) are becoming popular for their eco-friendly properties and versatility in various applications.
From Cornstarch to 3D Prints: The Journey of PLA Filaments
Derived from renewable resources such as cornstarch, cassava, and sugar beets, PLA has gained popularity for its sustainable appeal. The journey of PLA begins with extracting starch from these plants and fermenting it into lactic acid. This lactic acid then polymerizes into PLA, an environmentally considerate material.
Filamatrix advises that PLA is best for smaller projects due to its rapid breakdown. It’s a plant-based material ideal for businesses creating food-contact products, but it’s not heat-resistant and wears down with use.
PLA boasts superior biodegradability under industrial composting conditions, allowing it to decompose into harmless elements when properly disposed of. This feature sets it apart from other printing materials like ABS, which is notorious for contributing to environmental degradation. PLA filaments are highly versatile in their applications, often employed in producing prototypes, accessories, and a wide range of 3D printed items.
Biodegradable vs. Non-Biodegradable: Why It Matters
The distinction between biodegradable and non-biodegradable materials in 3D printing is crucial for environmental sustainability. PLA and other bio-based or biodegradable materials hold an advantage as they can be consumed by bacteria in industrial composting facilities, breaking down into their natural elements without leaving harmful residues.
Non-biodegradable plastics, such as ABS, are not broken down naturally and contribute to an increase in plastic waste in our environment. Therefore, a shift towards materials that decompose is an essential strategy for minimizing the ecological footprint of additive manufacturing and promoting a more sustainable future.
| Material | Biodegradable? | Derived From | Common Applications |
|---|---|---|---|
| PLA | Yes | Cornstarch, Cassava, Sugar beets | Prototypes, Accessories, Home Décor |
