PolyCore™ products are available in two pellet sizes. The standard pellet size has a diameter of 3-4mm and a length of 4-6mm (all measurements are averages). The mini pellet size, on the other hand, has a diameter of 1-2mm and a length of 2-4mm (average numbers as well). The standard pellet size is suitable for most big area additive manufacturing (BAAM) printers. However, for smaller printers with a small extruder and shallow spiral groove, we recommend using the mini pellet size to ensure a smooth printing process.
