3D printers use various consumables, also known as filaments, to create three-dimensional objects. The most common types of 3D printer filaments include:
PLA (Polylactic Acid): PLA is a biodegradable and environmentally friendly filament made from renewable resources such as corn starch or sugarcane. It’s popular for its ease of use and low odor.
ABS (Acrylonitrile Butadiene Styrene): ABS is a thermoplastic polymer that is durable and impact-resistant. It has a higher melting point compared to PLA and is commonly used for functional parts.
PETG (Polyethylene Terephthalate Glycol): PETG is a strong and transparent filament with good chemical resistance. It combines the ease of printing with the durability of materials like ABS.
TPU (Thermoplastic Polyurethane): TPU is a flexible filament with rubber-like properties. It is commonly used for printing flexible and elastic parts, such as phone cases or shoe insoles.
Nylon: Nylon is a strong and durable filament with good impact resistance. It is suitable for a wide range of applications, including gears and mechanical components.
Woodfill/Carbon Fiber/ Metal-filled Filaments: These filaments contain particles of wood, carbon fiber, or metal, adding unique properties to the printed objects, such as a wood-like finish or increased strength.
HIPS (High Impact Polystyrene): HIPS is often used as a support material for printing complex structures with ABS. It dissolves in Limonene, leaving the ABS part intact.
PVA (Polyvinyl Alcohol): PVA is a water-soluble filament used as a support material for printing complex structures with PLA. It dissolves in water, leaving the PLA part intact.
ASA (Acrylonitrile Styrene Acrylate): Similar to ABS, ASA has better UV resistance, making it suitable for outdoor applications.
PEEK (Polyether Ether Ketone): PEEK is a high-performance filament with excellent mechanical and thermal properties. It is used in demanding industrial applications.
These are just a few examples, and new filament types are continually being developed to meet specific needs in the 3D printing community. The choice of filament depends on the specific requirements of the printed object, such as strength, flexibility, transparency, or heat resistance.
