Polyamide 12 Materials study of morpho-structural changes during laser sintering of 3D printing

Original language description

The polyamide PA12 material used for additive manufacturing was studied in aspects of morphology and their structural properties for basic stages received during 3D laser printing. Samples were real big scale production powders. The structure of polymer was evaluated from the crystallinity point of view using XRD, FTIR and DSC methods and from the surface properties using specific surface evaluation and porosity. . Results were confronted with laser diffraction particles size measurement along with evaluation of specific surface area. Fresh PA12 powder was found as inhomogeneous in particle size of material with defective particles, relatively high specific surface, high lamellar crystallite size and low crystallinity. The scrap PA12 crystallinity is higher about 2 % than values for fresh PA12 powder, particles has very low, below 1m2/g, specific surface area particles sintered in twin&apos;s particle and often in polyhedral shapes.
