PLA is produced from renewable resources including the sugar in maize and sugarcane. The sugar is fermented and turned into lactic acid, which is then turned into polylactic acid. PLA is the most popular 3D printing material for FDM technology and can be easily sanded and painted with acrylic. Outside of additive manufacturing, this plastic is found in food containers, candy wrappers, and biodegradable medical implants such as sutures. PLA is soluble in chlorinated solvents, hot benzene, tetrahydrofuran, and dioxane.
