PLA
Also known as: Polylactic Acid, PLA Filament, PLA+
The most popular 3D printing filament, made from renewable resources like corn starch.
PLA (Polylactic Acid) is the most widely used 3D printing filament. Made from renewable resources like corn starch or sugarcane, it’s biodegradable, easy to print, and produces minimal odor.
Why PLA Is Popular
- Easy to print - Low warping, good bed adhesion
- No heated bed required - Works at room temperature (though 50-60°C helps)
- Low odor - Safe for indoor printing
- Wide color selection - Available in every color imaginable
- Affordable - Generally the cheapest filament option
Print Settings
| Setting | Value |
|---|---|
| Nozzle Temp | 190-220°C |
| Bed Temp | 50-60°C (or none) |
| Print Speed | 40-60mm/s |
| Cooling | 100% after first layer |
Limitations
- Low heat resistance - Softens around 60°C
- Brittle - Can crack under stress
- Not weather resistant - Degrades in sunlight/moisture over time
- Limited flexibility - Snaps rather than bends
Best Uses
- Prototypes and models
- Decorative items
- Cosplay props
- Toys and figurines
- Low-stress functional parts
Variants
- PLA+ - Enhanced with additives for better strength
- Silk PLA - Shiny, metallic appearance
- Matte PLA - Non-reflective finish
- Wood/Metal PLA - Contains wood or metal particles
