Problems solved by technology

Although high-strength structures can be fabricated continuously using pultrusion, the resulting structures can lack the form (shape, size, precision, and / or surface texture) required for some applications
In addition, conventional pultrusion manufacturing methods may lack precise control over curing and the ability to dynamically change materials in composites during fabrication.
Furthermore, the diversity of patterns and shapes integrated within pultruded structures can be limited, thereby limiting the usable properties of the resulting structures.

Embodiment Construction

[0014] figure 1 An exemplary system 10 is shown that can be used to continuously manufacture composite structures 12 having any desired cross-sectional shape, such as circular, rectangular, or polygonal. System 10 may include at least one frame 14 and head 16 . The head 16 may be coupled to and moved by the frame 14 . in the published figure 1 In an embodiment, the support 14 is a robotic arm capable of moving the head 16 in multiple directions during fabrication of the structure 12 such that the longitudinal axis (eg, trajectory) of the formed structure 12 is three-dimensional. The frame 14 may alternatively be implemented as an overhead crane frame or a hybrid crane frame / arm, which is also capable of moving the head 16 in multiple directions during fabrication of the structure 12 . Although the carriage 14 is shown as capable of 6-axis movement, it is contemplated that any other type of carriage 14 capable of moving the head 16 in the same or a different manner may be ut...

Abstract

A compactor is disclosed for use with an additive manufacturing print head. The compactor may include a housing connectable to the additive manufacturing print head. The compactor may also include a compacting wheel, and at least one spring disposed in the housing and configured to exert an axial force on the compacting wheel. The compactor may further include a piston moveable to adjust a distance between the housing and the compacting wheel.

Description

[0001] related application [0002] This application is based upon and claims the benefit of priority from US Provisional Application No. 62 / 611,922, filed December 29, 2017, the contents of which are expressly incorporated herein by reference. technical field [0003] The present disclosure relates generally to manufacturing systems, printheads, and compactors, and more particularly to compactors for additive manufacturing printheads and systems. Background technique [0004] Extrusion manufacturing is a known process for producing continuous structures. During extrusion manufacturing, a liquid matrix, such as a thermoset resin or heated thermoplastic, is pushed through a die with the desired cross-sectional shape and dimensions. The material solidifies and hardens to its final form after leaving the mold. In some applications, ultraviolet light and / or ultrasonic vibrations are used to accelerate the curing of the liquid matrix as it exits the mold. Structures produced b...
