The choice of the best 3D printer filament depends on the specific requirements of your project and the characteristics you prioritize. Here are some popular 3D printer filament types along with their key features:

PLA (Polylactic Acid): PLA filament is one of the most commonly used filaments. Especially PLA+, is modified based on PLA material, easy to print. In addition, PLA+ improves the toughness and layer adherence. PLA filament is suitable for a wide range of applications, including prototyping, hobbyist projects, and educational purposes.

PETG (Polyethylene Terephthalate Glycol-Modified): PETG filament combines the properties of both PLA and ABS. It offers good strength, durability, and temperature resistance, making it suitable for mechanical parts, containers, and outdoor applications. PETG filament is also more flexible and less brittle than PLA and ABS.

TPU (Thermoplastic Polyurethane): TPU filament is a flexible filament that is ideal for printing rubber-like parts, such as gaskets, phone cases, and wearables. TPU filament has high hardness and good resilience, can be used for insoles and other applications.

Ultimately, the best 3D printer filament choice depends on your specific needs, including the desired properties of your printed object, its application, and your printer's capabilities. It's always recommended to refer to your printer's manufacturer guidelines for compatible filaments and experiment with different materials to find the one that suits your requirements best.
