Title: Ghassan Al-Chaar: Innovator in 3D Printing and Construction Materials
Introduction
Ghassan Al-Chaar is a notable inventor based in Champaign, IL (US). He has made significant contributions to the fields of three-dimensional printing and construction materials. With a total of 5 patents to his name, Al-Chaar continues to push the boundaries of innovation.
Latest Patents
One of his latest inventions is a scalable three-dimensional printing apparatus. This apparatus is capable of movement along three axes and includes a tractor assembly that is movable along a selectively extendable rail component. The wheels in the tractor assembly surround part of the rail component, enabling the movement of a gantry bridge in a longitudinal direction along the rails. A movable printing trolley moves horizontally along the gantry bridge and features a printing column that can move vertically. This unique design allows users to print in three dimensions, and the selective extension of the rails enables users to alter the lengthwise printing scale.
Another significant patent is related to flowable slag-fly ash binders for construction or repair. This method involves providing a binder mixture that includes an alkali metal silicate, fly ash, slag, and added water. The total water-to-solids mass ratio of the binder mixture ranges from about 0.2 to 0.5. The binder mixture is then mixed with inert particles to form a flowable mortar, which is distributed over a bed of coarse aggregate. Upon curing, a composite comprising reinforcement material embedded in a cured binder is formed.
