PLA has a lower melting point and prints easier than other materials. One of the most important features is that PLA is non-toxic, and even has a sweet smell when printing. PLA has a low shrinkage rate and it is very rigid with minimal flex. This material can print extremely high-resolution models and is perfect for a wide range of uses. PLA is considered stronger than ABS but is more susceptible to cracking when subjected to flexing, impact or torsional loads so the mechanical needs of the print project need to be evaluated.
