What is 3d printer filament？

3D filament is the material used by 3D printers to create physical objects. 3D printer filament is a long and thin strand of material that is fed into the printer's extruder and melted to create a 3D object layer by layer. 3D Filament is available in a variety of materials, such as PLA filament, ABS filament, PETG filament, TPU filament,ASA filament , and many others, each with their own properties and characteristics.

What are the popular 3d printer filament types?
PLA (Polylactic Acid): PLA filament is a biodegradable thermoplastic material made from renewable resources such as corn starch or sugarcane. It is one of the most popular 3d printer filament types for 3D printing due to its ease of use and versatility. PLA filament can produce detailed and high-quality prints with a glossy finish.
ABS (Acrylonitrile Butadiene Styrene): ABS filament is a strong, durable, and impact-resistant thermoplastic material. It is commonly used in automotive parts, toys, and household appliances. ABS filament is a popular choice for 3D printing due to its high strength and toughness.
PETG (Polyethylene Terephthalate Glycol): PETG filament is a strong and flexible material that is resistant to impact and UV radiation. It is commonly used in the production of water bottles, food containers, and medical equipment. PETG filament is a popular choice for 3D printing because of its ease of use and durability.
TPU (Thermoplastic Polyurethane): TPU filament is a flexible and rubber-like material that is commonly used in the production of phone cases, shoe soles, and other flexible objects. TPU filament is a popular choice for 3D printing because of its flexibility, durability, and ability to create objects with complex shapes.
ASA (Acrylonitrile Styrene Acrylate): ASA filament is a weather-resistant thermoplastic material that is commonly used in outdoor applications. ASA filament is a popular choice for 3D printing because of its ability to withstand UV radiation, moisture, and heat.
Overall, choosing the right 3D printer filament for your 3D printing project requires a balance of the desired properties, printability, and cost. Experimenting with different materials can help you find the best 3D filament for your specific application.
