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 flexing, impact or torsional loads so the mechanical needs of the print project has to be evaluated.PLA has a huge range of vibrant colors and opacity for that perfect look whether it is artistic or utilitarian, in short a great material for 3D printing. PLA can be printed without the use of a heat bead, and can stick to glass or a PCB plate with a binder such as hairspray or white glue for a curl free print. 3D printing is a fun and exciting hobby with a wide range of uses from prototyping parts to making toys for the kids. Picking the right filament for your application is very important.
