Filament

Definition

Filament is the thermoplastic material — typically supplied as 1.75mm or 2.85mm diameter spools — that FDM 3D printers melt and extrude to create parts layer by layer.

In Practice

Common filaments include PLA (easy, biodegradable), ABS (heat-resistant, tough), PETG (chemical-resistant, strong), nylon (wear-resistant, flexible), and polycarbonate (strongest, transparent). The Epicblaze v1 supports all standard 1.75mm filaments and — thanks to its 350°C all-metal hotend — handles advanced composites like carbon-fiber nylon and glass-filled polycarbonate that most desktop printers cannot. Proper filament storage (dry, sealed containers) is critical for hygroscopic materials like nylon and PC, which absorb moisture from air and produce weak, bubbly prints when wet.
