3d printing method using polymerizable liquid and solidifiable component

A patent application (Publication Number: US20240034000A1) discloses a method for forming a three-dimensional object using a polymerizable liquid mixture. The method involves providing a carrier and an optically transparent member with a build surface, filling the build region between them with the polymerizable liquid mixture containing a light polymerizable liquid first component, a second solidifiable component, a photoinitiator, and an organic peroxide. The build region is irradiated with light to form a solid polymer scaffold and the carrier is moved away to create a three-dimensional intermediate with the second solidifiable component in unsolidified form. Subsequently, the unsolidified component is heated or microwave irradiated to form the final three-dimensional object.
The method allows for the creation of various types of three-dimensional objects, including elastomeric, rigid, semi-rigid, or flexible structures. The organic peroxide in the polymerizable liquid reacts with any unreacted double bonds during the heating or microwave irradiation process. Additionally, the polymerizable liquid mixture may contain a reactive diluent such as acrylates, methacrylates, styrenes, acrylic acids, vinylamides, vinyl ethers, or vinyl esters to enhance the properties of the final object. The method also involves maintaining a dead zone of polymerizable liquid in contact with the build surface and a gradient of polymerization zone between the dead zone and the solid polymer scaffold to ensure proper curing of the material. Overall, this innovative method offers a versatile approach to creating complex three-dimensional objects with customizable properties.
