PLA – Everything You Need to Know
Most popular 3D printing material – when to use it and when not.
PLA (Polylactic Acid) is the most commonly used material for FDM 3D printing:
✅ Advantages: • Easiest to print – suitable for beginners • Biodegradable (compostable under industrial conditions) • Minimal warping during printing • Low printing temperature (190–220 °C) • Available in hundreds of colors • Relatively inexpensive
⚠️ Disadvantages: • Low heat resistance (~55–60 °C) • Brittle under impact • Susceptible to UV degradation • Not suitable for long-term outdoor use
🌡 Print settings: • Nozzle: 195–215 °C • Bed: 55–65 °C (or unheated) • Cooling: 100% • Speed: 40–150 mm/s
🔧 PLA variants: • PLA+: Better toughness, higher temperature • PLA-CF: Carbon fiber, stronger, matte finish • Silk PLA: Glossy silky surface • Wood/Metal/Marble filament: Aesthetic variants
