... printed specimens and decreased by 73% and 83% for 3- and 5-layer, respectively, while each layered non-annealed specimen subjected to degradation at 37°C for one month. Within the outlined study, annealing treatment enhances properties such as the degree of crystallinity (%χ) up to 34%, Young’s modulus...

..., since it can take up to 4.5 times the building time. The purpose of this paper is to investigate into effects of cooling rate on parts manufactured by multi jet fusion. Crystallinity, density, distortions and mechanical properties of specimens produced through an HP multi jet fusion 4200 are examined...

... of both designs. In addition, the flow behavior and yield of both methods are compared, taking into account the preservation of product quality in terms of shape, size and polymer crystallinity. High-density polyethylene (PE-HD) (Coathylene® NB 645374, Axalta Polymer Powders, Switzerland...
