Abstract :

Additive Manufacturing of components via Binder jetting enables the production of complex geometries. The objective of this work is to fabricate and carry out trails on a powder-based three dimensional printer. During the work a prototype system was manufactured and, during subsequent testing, was found to successfully print objects by applying a binder to multi-mode gypsum based powder. During binder jetting, a polymer binder (Bentonite, dextrin, edible oil, water, resins) is printed onto a bed of powder using a traditional inkjet print head to form one cross-sectional layer of the part. After a layer of binder is printed, the powder bed lowers, and fresh powder is spread over the powder bed atop the previous layer. In this manner, the object is constructed layer by layer. After the part is printed, the excess powder is removed using compressed air or vacuum, it is simple for an end user to perform.
