Abstract:
3D printing is a new, rapidly developing technology which has the potential to revolutionise fabrication of certain high value, complex products. It is the preparation of an object by progressive addition of material layers. The main disadvantages of additive manufacturing are the limited material types that can be processed in this way and the fact that the material properties are often inferior to those used in more conventional preparation methods. Polylactide (PLA) has been becoming a very important polymer in the 3D printing processing, considering its low toxicity and its better environmental friendliness, compared to all the petroleum-based plastics. PLA belongs to the family of aliphatic polyesters derived from renewable resources, such as corn starch, sugar cane, tapioca roots or even potato starch and has a narrow processing window due to its tendency to undergo thermal decomposition in the molten state.

Key words:
PLA, printing, aliphatic polyesters, bio-based polymer
