PHA (Polyhydroxyalkanoates) filament is a type of bioplastic that is similar to PLA in terms of biodegradability but offers improved toughness and UV resistance. This material is derived from microbial fermentation processes, making it an environmentally friendly option. PHA is known for its durability, UV resistance, and ability to withstand outdoor environments better than PLA, without sacrificing biodegradability.

Unique Features: Enhanced durability and flexibility compared to PLA, biodegradable, with good UV resistance, making it more suitable for outdoor use.
Ideal Use Case: Suitable for outdoor applications where biodegradability and resistance to environmental factors are important, such as plant pots, outdoor signage, or eco-friendly consumer products.
Additional Components: PHA can be printed similarly to PLA but may require slightly higher temperatures for optimal flow and adhesion. No specific additional components are needed beyond standard 3D printing setups.
