Abstract:
A method of additively manufacturing composite part comprises depositing a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and further comprises a photopolymer-resin component that is uncured. The method further comprises delivering a predetermined or actively determined amount of curing energy at least to a portion of the segment of the continuous flexible line at a controlled rate while advancing the continuous flexible line toward the print path and after the segment of the continuous flexible line is deposited along the print path to at least partially cure at least the portion of the segment of the continuous flexible line.

Abstract:
A method of additively manufacturing a composite part comprises pushing a continuous flexible line through a delivery guide. The continuous flexible line comprises a non-resin component and a photopolymer-resin component that is partially cured. The method also comprises depositing, via the delivery guide, a segment of the continuous flexible line along a print path. Additionally, the method comprises delivering curing energy at least to a portion of the segment of the continuous flexible line deposited along the print path.
Abstract:
A threaded adjustable-height insert may be installed in a bore of a sandwich panel, such that the insert may be configured to transfer a load to the sandwich panel. The threaded adjustable-height insert may include a first insert part and a second insert part that may be selectively operatively positioned with respect to each other. The overall height of the threaded adjustable-height insert may be adjusted by longitudinally sliding the second insert part with respect to the first insert part and rotating the second insert part with respect to the first insert part. Presently disclosed threaded adjustable-height inserts may be configured for flush installation in a sandwich panel. Methods of installing such threaded adjustable-height inserts and adjusting the height of the same are also disclosed.
Abstract:
A system (100) for additively manufacturing a composite part (102) comprises a delivery assembly (266), a feed mechanism (104), and a source (116) of curing energy (118). The delivery assembly (266) comprises a delivery guide (112) movable relative to a surface (114) and is configured to deposit a continuous flexible line (106) along a print path (122). The delivery assembly (266) further comprises a first inlet (170), configured to receive a non-resin component (108), and a second inlet (250), configured to receive a photopolymer resin (252). The delivery assembly (266) applies the photopolymer resin (252) to the non-resin component (108). The feed mechanism (104) pushes the continuous flexible line (106) out of the delivery guide (112). The source (116) of the curing energy (118) delivers the curing energy (118) to a portion (124) of the continuous flexible line (106) after it exits the delivery guide (112).
Abstract:
A system (100) for additively manufacturing a composite part (102) is disclosed. The system (100) comprises a housing (104) and a nozzle (107). The nozzle (107) is supported by the housing (104). The nozzle (107) comprises an outlet (110), sized to dispense a continuous flexible line (112). The continuous flexible line (112) comprises a non-resin component (114) and a photopolymer-resin component (116). The system (100) also comprises a feed mechanism (118), supported within the housing (104). The feed mechanism (118) is configured to push the continuous flexible line (112) out of the outlet (110) of the nozzle (107). The system (100) further comprises a light source (120), supported by the housing (104). The light source (120) is configured to deliver a light beam to the continuous flexible line (112) after the continuous flexible line (112) exits the outlet (110) of the nozzle (107) to at least partially cure the photopolymer-resin component (116) of the continuous flexible line (112).
Abstract:
A method (500) of additively manufacturing a composite part (102) comprises applying a first quantity of a first part (253) of a thermosetting resin (252) to a first element (271) of a non-resin component (108) by pulling the first element (271) through a first resin-part applicator (236) and applying a second quantity of a second part (255) of the thermosetting resin (252) to a second element (273) of the non-resin component (108) by pulling the second element (273) through a second resin-part applicator (237). The method (500) also comprises combining the first element (271) with the first quantity of first part (253) and the second element (273) with the second quantity of second part (255), to create a continuous flexible line (106). The method (500) additionally comprises routing the continuous flexible line (106) into a delivery guide (112) and depositing, via the delivery guide (112), a segment (120) of the continuous flexible line (106) along a print path (122).
Abstract:
A method (400) of additively manufacturing a composite part (102) comprises applying a liquid photopolymer resin (252) to a non-resin component (108) to create a continuous flexible line (106) by pulling the non-resin component (108) through a vessel (236), containing a volume of the liquid photopolymer resin (252).
