Abstract
3D printing, a form of additive manufacturing, is quickly gaining popularity as a means of production in applications ranging from the consumer hobbyist up to the demands of industry. Since its realization in 2009, concrete-based 3D printing has been steadily moving closer to commercial use. As an innovative technology, layered concrete deposition lacks any significant history concerning safety and durability, particularly when subjected to stressors, such as impacts [1]. When considering 3D printing as a method of construction, resilience to structural deformation is critical to determine long-term viability, especially for structures erected in unvaryingly hostile environments. Quickly and accurately assessing the integrity of a structure that has been impacted is paramount to making versatile, additively manufactured concrete structures. With that in mind, this paper lays the groundwork for using a mesh of FBG (Fiber Bragg Grating) sensors imbedded in a 3D printable concrete mixture to recognize impacts in real-time and triangulate their exact position.
