Carbon had 12 patents in 3D printing during Q2 2024. Carbon Inc’s patents filed in Q2 2024 focus on innovative methods for creating three-dimensional objects using polyurea. The first patent describes a method involving dispensing a dual cure resin into a stereolithography apparatus, additively manufacturing an intermediate object, cleaning it, and then reacting the polymerization product with water to generate polyamine and form urea linkages to produce the final object. The second patent details a method for separating excess resin from objects produced using stereolithography by centrifugally spinning the objects on carrier platforms to remove the excess resin. The third patent outlines a method for forming three-dimensional objects by filling a build region with a polymerizable liquid mixture, irradiating it with light to form a solid blocked polymer scaffold, and then solidifying the second solidifiable component to create the final object.

Application: One part, catalyst containing, moisture curable dual cure resins for additive manufacturing (Patent ID: US20240131779A1)
The patent filed by Carbon Inc. describes a method for producing a three-dimensional object made of polyurea using a one-part dual cure resin. The process involves dispensing the resin into a stereolithography apparatus, additively manufacturing an intermediate object, optionally cleaning it, and then reacting the polymerization product with water and a catalyst to form urea linkages and create the final three-dimensional object. The resin includes components such as a photoinitiator, a reactive blocked polyisocyanate, a catalyst, and optionally a polyepoxide and water. Various specific formulations and constituents are detailed in the claims, including the use of specific catalysts, polyepoxides, blocking agents, and additional additives like diluents, pigments, and flame-retardants.
The patent claims outline the composition of the one-part dual cure additive manufacturing resin, specifying the inclusion of a photoinitiator, a reactive blocked polyisocyanate, a catalyst, and optional components like polyepoxides and water. Specific details are provided regarding the types of catalysts, polyepoxides, and blocking agents that can be used in the resin formulation. The claims also cover the potential inclusion of additional constituents such as diluents, pigments, and flame-retardants, highlighting the versatility and customization options available in the resin composition.
