PLA is an easy to use 3D printer filament in comparison to other polymers that can be printed using low-to-moderate temperatures with a higher throughput on FFF 3D printers. Its mechanical properties, as well as other final properties, are widely variable depending on the 3D printing conditions such as extruder temperature, extrusion speed, cooling system, etc.
Compared to other polymers used for 3D printing, PLA demonstrates much less warping and shrinkage. For this reason it’s possible to successfully print in an open environment without a dedicated cooling system. For applications at higher humidity (above 98%) and higher temperatures (above 60°C) other polymers, such as BigRep’s Pro HT and PETG, are recommended.
