Coupled with low running costs, binder The materials commonly used in Binder Jetting are metals, sand, and ceramics that come in a granular form. This porosity can be reduced by sintering (producing 97% dense parts) or infiltration (90% dense parts), but it can leave voids that lead to crack initiation. Moreover, as the part shrinks during sintering, there here is friction between the plate of the furnace and the lower surface of the part, which may lead to warping. In general, theMBJis preferably dedicated to parts of limited size because the step of dusting green parts is tricky for those of very large size. Then, a carriage with inkjet nozzles (which are similar to the nozzles used in desktop 2D printers) passes over the bed, selectively depositing droplets of a binding agent (glue) that bond the powder particles together. The main printhead first jets the binding agent, while a secondary print head jets a colored ink. For sintering, the part shrinkage is approximately 20%. Binder jetting offers unique material options compared to The advantages of binder jetting include less warping as it takes place at room temperature, as well as being less expensive than many other methods and able to deliver high-volume production. Depending on the part's size, AM can be much as 5-100x the cost of a traditional powder metal part.
