3D Printer Filaments
24 products
3D printer filaments are thermoplastic threads used as the core material in FDM/FFF printers. Selecting the right filament directly influences part durability, surface finish, and print success. Each material offers distinct melting points, flexibility, strength, and environmental resistance.
The table below summarizes the most common filament types and their primary characteristics:
| Filament | Key Feature | Typical Nozzle Temp |
|---|---|---|
| PLA | Easy to print, low odor, biodegradable | 190-220°C |
| ABS | High impact resistance, heat tolerance | 230-250°C |
| PETG | PLA ease + ABS durability, chemical resistance | 220-250°C |
| TPU | Flexible, rubber-like, shock absorbent | 210-230°C |
When choosing filament, pay close attention to diameter tolerance (±0.05 mm or better) for consistent extrusion. Moisture-sensitive materials (ABS, PETG, nylon) require dry storage and occasional drying to prevent print defects. Bed adhesion strategies—bed temperature, masking tape, PEI sheets, or adhesive sprays—vary by filament type and are crucial for warp-free prints.
