PLA is a good choice for a printing material if you are looking for high accuracy and high resolution. It extrudes at lower temperaturesdoes not require a heated baseand has a very low shrinkage rate (0.3%). PLA is harder than ABSbut is therefore also a bit more brittle. AdditionallyPLA is a plant-based plasticwhich means that it is biodegradable and gives off a slightly sweet odorlike roasting corn.
This 1 Kg spool features a thickness of 1.75mm ±0.10mmwith 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 moisturesunlightand heat. Additionallyit is more prone to overheating during processingwhich can cause dripping and drooping if it gets too hot
