Latest Patents

One of his latest patents is titled "Managing powder mobility in binder jetting for additive manufacturing." This invention involves devices, systems, and methods that utilize vapor phase change in binder jetting processes. The process aims to form three-dimensional objects by directing vapor of a first fluid to a layer of powder. The vapor condenses to reduce the mobility of the powder particles, thereby minimizing the likelihood of particle ejection and printhead clogging. Additionally, this method increases the density of the powder, which helps prevent slumping during sintering.

Another significant patent is "Multi-directional binder jetting additive manufacturing." This invention focuses on powder spreading and binder distribution techniques that enable consistent and rapid layer-by-layer fabrication of three-dimensional objects. The method involves spreading powder to form a layer and depositing binder in different directions, facilitating the rapid formation of the object while maintaining quality standards.
