Processes such as this may boost PLA’s presence in the plastics market, as improving the mechanical properties will be important to replace current petroleum-derived plastics. It has also been demonstrated that the addition of a PLA-based, cross-linked nucleating agent improved the degree of crystallinity of the final PLA material. [ 7 ]
The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content.
Ingeo is a range of polylactic acid (PLA) biopolymers owned by NatureWorks. [1] Resinex Group distributes Ingeo in Europe. [2] Ingeo is created using carbon stored in plants via photosynthesis and takes the form of dextrose sugar. These sugars are then converted into a biopolymer through the processes of fermentation and separation.
This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260–300 °C. The surface can be printed, hot-stamped, painted or metallized. Welds are possible by means of heating element, friction or ultrasonic welding. It can be glued with halogenated solvents or various adhesives.

The company began as a start-up at SolidWorks World 2014 in San Diego with a working prototype of the "Mark One" printer, capable of printing in continuous carbon fiber (the first to do so), fiberglass, nylon and polylactic acid (PLA). [2] Production machines can also print kevlar. [5]
