By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-A patent by the inventors Stranberg, N athan Andrew (Post Falls, ID, US), Stulc, Andrew Michael (Spokane, WA, US), file d on February 18, 2022, was published online on March 12, 2024, according to new s reporting originating from Alexandria, Virginia, by NewsRx correspondents. Patent number 11926099 is assigned to Continuous Composites Inc. (Coeur d'Alene, Idaho, United States). The following quote was obtained by the news editors from the background informa tion supplied by the inventors: “Continuous fiber 3D printing (a.k.a., CF3D®) in volves the use of continuous fibers embedded within material discharging from a moveable print head. A matrix is supplied to the print head and discharged (e.g., extruded and/or pultruded) along with one or more continuous fibers also passi ng through the same head at the same time. The matrix can be a traditional therm oplastic, a liquid thermoset (e.g., an energy-curable single- or multi-part resi n), or a combination of any of these and other known matrixes. Upon exiting the print head, a cure enhancer (e.g., a UV light, a laser, an ultrasonic emitter, a heat source, a catalyst supply, or another energy source.) is activated to init iate, enhance, and/or complete curing of the matrix. This curing occurs almost i mmediately, allowing for unsupported structures to be fabricated in free space. When fibers, particularly continuous fibers, are embedded within the structure, a strength of the structure may be multiplied beyond the matrix-dependent streng th. An example of this technology is disclosed in U.S. Pat. No. 9,511,543 that i ssued to TYLER on Dec. 6, 2016 and incorporated herein by reference.
