PLA is a good choice for a printing material if you are looking for high accuracy and high resolution. It extrudes at lower temperatures, does not require a heated base, and has a very low shrinkage rate (0.3%). PLA is harder than ABS, but is therefore also a bit more brittle.
This 1 kg spool features a thickness of 1.75mm ±0.10mm, with a roundness variation of only 0.03mm. It has a nominal processing temperature of 210° C (410°F). Thickness and roundness factors are laser measured at the factory to ensure accuracy over the entire length of the filament.
The negatives of using PLA is that it is vulnerable to degradation from moisture, sunlight, and heat. Additionally, it is more prone to overheating during processing, which can cause dripping and drooping if it gets too hot.
