PLA Filament (Polylactic Acid)
Material Properties
Biodegradable, easy to print, low odor
Strong in X/Y directions but brittle; low impact resistance
Heat resistance: ~50–60°C, softens quickly under heat
Smooth surface finish, excellent for prototyping and visual models
Printing Temperature
Nozzle: 190–220°C
Heated bed: 50–60°C (optional for small prints)
Cooling: 50–100% fan, improves overhangs and surface quality
Print Considerations
Low warping; usually no enclosure needed
Easy to print at higher speeds: 40–70 mm/s
Layer adhesion generally reliable
Post-processing: sanding, painting; acetone smoothing not effective
Applications
Prototypes, decorative parts, and visual models
Jigs and fixtures with low mechanical load
Educational and hobbyist projects
