PLA 1.75mm filament for 3D printer
What is PLA filament?
PLA (polylactic acid) filament is a biodegradable bioplastic derived from renewable resources such as corn and sugarcane. It is one of the most popular materials for 3D printing due to its ease of use, versatility, and low environmental impact. It is characterized by:
- Easy to use:It does not require a heated bed and prints at relatively low temperatures.
- Versatile:It can be printed on a wide range of 3D printers.
- Biodegradable and non-toxic:It is a safe material for the environment and human health.
Origin and sustainability of PLA:
PLA is produced from renewable resources, making it a sustainable alternative to traditional petroleum-derived filaments. It's also biodegradable and compostable, meaning it breaks down naturally over time without leaving harmful residues.
PLA is biodegradable and compostable under industrial conditions. It breaks down into water and carbon dioxide, making it an environmentally friendly alternative to traditional filaments.
Differences between PLA and other filaments (ABS, PETG, TPU):
- ABS:ABS is a heat and abrasion resistant material, but it is less biodegradable than PLA and requires a heated bed for printing.
- PETG:PETG is water and chemical resistant, but is stiffer and less flexible than PLA.
- TPU:TPU is a flexible and abrasion-resistant material, but it is more difficult to print than PLA and requires specific printer settings.
