As 3D printing tries to make its way into mainstream manufacturing, there are still some kinks to be worked out. For aerospace companies, like Boeing, 3D printed parts need to meet a strict set of requirements before they can be incorporated into the death-defying world of air travel. The process of building an object up layer by layer in additive manufacturing leaves room for structural errors, as not all layers will have the same strength, stiffness, and all-around structural properties. When it comes to laser sintering nylon, one might see microscopic divots and craters spread throughout different layers.…
