PLA - Diameter tolerance - ± 0,03 mm

PLA – PolyLactic Acid  

PLA is the easiest filament for precise and clean 3D printing; compared to PETG it prints easier and offers better detail, but has much lower heat and mechanical resistance.
Advantages: very easy to print, minimal warping, excellent detail and surface finish.
Disadvantages: low heat resistance (~55–60 °C), brittleness, not suitable for outdoor or functional parts.
