Problems solved by technology

[0006] Although pultrusion fabrication can be an efficient way to continuously fabricate high-strength structures, the resulting structures may lack the form (shape, size, and / or precision) required for some applications
Additionally, conventional pultrusion manufacturing may lack flexibility in the types of matrices that can be used and / or the cure rates of those matrices

Embodiment Construction

[0014] figure 1 An exemplary system 10 is shown that may be used to continuously manufacture composite structures 12 having any desired cross-sectional shape (eg, circular, polygonal, etc.). System 10 may include at least a support 14 and a head 16 . Head 16 may be coupled to and moved by support 14 . exist figure 1 In the disclosed embodiment, support 14 is a robotic arm capable of moving head 16 in multiple directions during fabrication of structure 12 such that the resulting longitudinal axis of structure 12 is three-dimensional. However, it is contemplated that support 14 may alternatively be an overhead gantry, which is also capable of moving head 16 in multiple directions during fabrication of structure 12 . Although the support 14 is shown as capable of 6-axis movement, it is contemplated that any other type of support 14 capable of moving the head 16 in the same or a different manner could be used, if desired. In some embodiments, the drive may mechanically couple ...

Abstract

A head is disclosed for an additive manufacturing system. The head may include a nozzle configured to discharge a matrix reinforced with a fiber, and a plurality of light sources at least partially surrounding the nozzle. The plurality of light sources may be configured to enhance curing of the matrix. At least two of the plurality of light sources are configured to generate light within differentspectrums.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of priority to US Provisional Application Serial No. 62 / 417,709, filed April 11, 2016. The entire content of this patent application is incorporated herein by reference. technical field [0003] The present invention relates generally to a manufacturing system, and more particularly to an additive manufacturing system with a variable curing device. Background technique [0004] Extrusion manufacturing is a known method for producing continuous structures. During extrusion manufacturing, a liquid matrix (eg, a thermoset resin or heated thermoplastic) is pushed through a die having the desired cross-sectional shape and dimensions. Once the material leaves the mold, the material solidifies and hardens into its final form. In some applications, UV light and / or ultrasonic vibrations are used to accelerate the curing of the liquid matrix as it exits the mold. Structures produced...
