Continuous Composites Inc. recently secured a major technological breakthrough with the issuance of U.S. Patent No. US12773823B2. This patent, titled ‘System for additive manufacturing’, introduces an advanced method for controlling material feed in continuous fiber 3D printing. Manufacturers can now produce complex composite structures with enhanced precision and structural reliability.
IDAHO PATENT OF THE MONTH – NOVEMBER 2026
The innovation focuses on an intelligent tensioning system integrated into an additive manufacturing print head. The apparatus features a spring-biased tensioner arm equipped with rollers that guide the reinforcement material through an S-shaped trajectory. A sensor monitors the pivoting movement of this arm and generates a signal to dynamically adjust the feed rate of the material supply. The invention is highly innovative and won the Idaho Patent of the Month for November 2026 granted by Swanson Reed because it provides real-time, automated feedback to maintain optimal fiber tension during the printing process. Designed by inventors Nathan Andrew Stranberg, Andrew John Overby, and Colin Hugh Hambling, the technology ensures precise deposition and wetting of continuous reinforcements, overcoming previous limitations in composite 3D printing speed and accuracy.
Practical Applications and R&D Tax Credit Eligibility
The practical applications of this technology span across the aerospace, defense, and high-performance automotive industries, where the manufacturing of lightweight, load-bearing composite parts is essential. When businesses in the USA adopt or adapt this additive manufacturing system to develop new production processes, custom toolpaths, or improved resin delivery methods, the associated engineering efforts often involve a distinct process of experimentation. This systematic testing to evaluate fiber tension thresholds, system integration, and the mechanical properties of the final printed structures qualifies as permitted research activities under IRS guidelines. Consequently, companies investing time and resources into implementing and refining these advanced composite manufacturing techniques can capture significant Research and Development (R&D) tax credits, effectively reducing their financial burden while funding future technological progress.
