PLA (polylactic acid) is a commonly used 3D printing filament that is made from lactic acid, which is derived from natural resources such as corn starch or sugarcane.
One of the main advantages of PLA is that it is easy to print with. It has a low melting point, which means that it can be printed at relatively low temperatures. This makes it compatible with a widest range of 3D printers and hardware, from0 low-end ptfe lined hotends to high-end commercial printers. Additionally, it has good bed adhesion, which means that it can be printed directly on the build plate without the need for additional adhesives or coatings.
As a result of PLA’s excellent printability it is also known for producing very high-quality prints. It has a low warping and shrinkage rate, which means that the dimensions of the final print will be very accurate compared to its 3d model. It also has a smooth surface finish and is generally available in a wider range of colors compared to other materials, which makes it a popular choice for printing models, figurines, and other decorative items.
