Systems, devices, and methods for inkjet-based three-dimensional printing
Devices and methods are described that provide printing of three-dimensional objects using reactive materials such as materials that result in a polyurethane formulation. Three-dimensional printing in accordance with the present disclosure can be performed using an inkjet printer or other systems that deposit or dispense material. A formulation made up of two or more reactive materials and, optionally, one or more UV-curable materials is also provided. The materials can be jetted based on a desired configuration to achieve a maximum reaction between materials, and can be based on desired jetting or molar ratios. By heating or applying energy on the jetted materials, their reaction and related solidifying can be accelerated. Corrective printing is also provided for, and can be used at desired intervals to eliminate printing errors relative to the object as modeled. Systems and methods used in conjunction with all of the same are provided.
