In addition, three-dimensional objects that you make from PLA are flame-retardant and they burn very poorly. Both implants and sutures made of PLA can be safely absorbed by the human body.Īnother advantage of this material is its excellent resistance to UV radiation. PLA can be biodegraded and is therefore a debt-free alternative to filaments that are derived from petroleum and are not biodegradable.Įspecially in recent years, PLA has gained popularity as more and more people attach importance to environmentally friendly products.ĭue to its biodegradability and bioactivity, PLA is very popular in the medical field. The most significant finding is that polylactides are among the few plastics whose production is possible from sustainable sources.ĭue to its unique chemical composition, the weak lactic acid is environmentally friendly. In order for lactic acid to be completely isolated, the fermentation process must take place under strictly controlled conditions. PLA precursors made from lactic acid are produced by bacterial fermentation from an appropriate carbohydrate source.Ĭarbohydrates are already naturally rich in sugar, starch or waste products such as plant stems or cereal husks. One of the characteristic properties of PLA is the fact that this filament can be produced on plant material. Typical Characteristics of PLA Advantages of PLA Moreover, PLA, which is made from lactide, has a fairly high density. Thanks to these innovations, PLA is not only longer-lasting, but also more stable from a chemical point of view. In addition, the ring-opening polymerization process is used. Recently, many manufacturers have started using lactide as raw material instead of lactic acid. In recent years, the process for producing PLA has been drastically improved. This plastic filament is used in 3D printers based on Fused Deposition Technology.
