Polyamide 12 (PA12) is widely used in engineering for its excellent mechanical properties, chemical resistance, and ease of printing. Additive manufacturing (AM), especially Multi Jet Fusion (MJF), enables fast and flexible prototyping, offering a cost-effective alternative to traditional injection molding. Fast manufacturing of prototypes is essential, as it significantly reduces time and cost in the design process. However, AM parts often exhibit different mechanical behavior due to the anisotropic nature of the layer-by-layer process, emphasizing the need to thoroughly understand their performance early in the design workflow.
The work emphasizes the influence of printing orientation, loading mode (tension, compression, shear), and strain rate on material behavior.
