Abstract
An additive manufactured structure and methods for making and using same. The structure includes a plurality of layers stacked in a stacking direction. The structure further includes at least one reinforcement structure affixed to the layers and extending at least partially in the stacking direction. The reinforcement structure can hold the layers together to stiffen and strengthen the structure. Mechanical strength of the structure in the stacking direction can advantageously be improved. Shape and spatial distribution of the reinforcement structure can be customized and adapted to the geometry of the layers to enhance strengthening effect. The reinforcement structure can be tension free or have a compressive stress induced by a preload applied during manufacturing. The compressive stress can be adjusted dynamically via a sensor. The structure and methods provide, among other things, a novel means for addressing the inherent weaknesses in parts created by large-scale extrusion deposition processes.
