A method of additively manufacturing a composite part is disclosed. The method comprises depositing, via a delivery guide, a segment of a continuous flexible line along a print path. The continuous flexible line comprises a non-resin component and a thermosetting-epoxy-resin component that is partially cured. The method also comprises maintaining the thermosetting-epoxy-resin component of at least the continuous flexible line being advanced toward the print path via the delivery guide below a threshold temperature. The method further comprises delivering a predetermined or actively determined amount of curing energy to the segment of the continuous flexible line at a controlled rate while advancing the continuous flexible line toward the print path to at least partially cure the segment of the continuous flexible line.

A method of additively manufacturing a composite part comprises applying a first quantity of a first part of a thermosetting resin to a first element of a non-resin component by pulling the first element through a first resin-part applicator and applying a second quantity of a second part of the thermosetting resin to a second element of the non-resin component by pulling the second element through a second resin-part applicator. The method also comprises combining the first element with the first quantity of first part and the second element with the second quantity of second part, to create a continuous flexible line. The method additionally comprises routing the continuous flexible line into a delivery guide and depositing, via the delivery guide, a segment of the continuous flexible line along a print path.

A method of additively manufacturing a composite part comprises applying a thermosetting resin to a non-resin component to create a continuous flexible line by pulling a non-resin component through a first resin-part applicator, in which a first quantity of a first part of the thermosetting resin is applied to the non-resin component, and by pulling a non-resin component through a second resin-part applicator, in which a second quantity of a second part of the thermosetting resin is applied to at least a portion of the first quantity of the first part of the thermosetting resin, applied to the non-resin component. The method further comprises routing the continuous flexible line into a delivery guide and depositing, via the delivery guide, a segment of the continuous flexible line along a print path.

A wheel with a rim as well as a wheel spider, where the wheel spider has a hub and spokes. The wheel includes spokes including one or more linearly stretched textile strands as reinforcement material of a fiber composite and each linearly stretched textile strand runs at least once from the rim to the hub and back without interruption and thus forms at least one spoke. The textile strands are connected in a positive-locking manner and/or in substance with the hub and the rim. A process is provided for the manufacture of the wheel.

A bead core for a tire is provided. The bead core is formed from a carbon fiber composite. The bead is formed into the shape of a hoop or ring before the carbon fiber composite is fully cured. The strain present in the carbon fiber composite after forming the ring, via finally curing with energy sources (218) the carbon fiber composite firstly treated with a resin bath and shaped as a precursor (214), which is then wrapped onto a roller (216) before curing, is carefully controlled to be less than 0.1 percent. A tire incorporating such a bead core within the bead portions of the tire can have improved weight relative to a tire with conventional, steel bead core constructions.

A method of additively manufacturing a composite part comprises applying a photopolymer resin to a non-resin component while pushing a continuous flexible line through a delivery assembly. The continuous flexible line comprises the non-resin component and a photopolymer-resin component that comprises at least some of the photopolymer resin applied to the non-resin component. The method also comprises depositing, via the delivery assembly, a segment of the continuous flexible line along a print path. The method further comprises delivering curing energy to at least a portion of the segment of the continuous flexible line deposited along the print path.

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.

An apparatus and method for three-dimensional printing of composite materials of continuous fibre, in which a feed head for feeding a compound material of continuous fibre is moved so as to print a three-dimensional object; a means for relative movement between the feed head and the three-dimensional object exerts a drawing force on the compound material of continuous fibre, so as to bring about the feeding of the material; this material is realized at a station arranged upstream of the feed head.

A long fiber extrusion apparatus applies a polymer melt to a length of fiber using a die and an extruder where the length of fiber is directed to the die through a glass tube. The transparency of the glass tube enables viewing of the fiber as it is directed through the glass tube to monitor for any difficulties or problems encountered by the fiber passing through the glass tube. The glass interior surface of the glass tube reduces friction between the fiber and the glass surface and thereby reduces abrasion of the fiber and dust produced from abrasion of the fiber inside the glass tube.

Methods, apparatus, and systems for cutting material used in fused deposition modeling systems are provided, which comprise a ribbon including one or more perforations. Material is passed through at least one perforation and movement of the ribbon cuts the material. A further embodiment comprises a disk including one or more blade structures, each forming at least one cavity. Material is passed through at least one cavity and a rotational movement of the disk cuts the material. A further embodiment comprises a slider-crank mechanism including a slider coupled to a set of parallel rails of a guide shaft. The slider moves along a length of the rails to cut the material. Yet another embodiment comprises one or more rotatable blade structures coupled to at least one rod. The rotation of the blade structures causes the blade structures to intersect and cut extruded material during each rotation.
