Metal 3D Printing
The AMI is excited to announce that a second, larger ExOne metal 3D printer, the M-Flex, will be arriving this coming August. The AMI is getting its own space, it will be located in Dana Labs on the ground floor of Acopian Engineering Center. This space will house the M-Flex as well as two Ultimaker2’s. Learn more on the Metal 3D Printing page.
The AMI currently has an ExOne 3D metal printer that uses inkjet technology to produce 3D printed metal parts with a build box of 1.5 x 2.3 x 1.3 inches. The AMI is in the process of expanding and will soon be home to ExOne’s M-Flex that prints 10x faster than previous generations and has a build box of 15.7 x 9.8 x 9.8 inches.
The ExOne Prometal 3D printing process involves three steps: printing, curing, and infiltration/sintering. During part printing binder is jetted, layer by layer, through a printhead onto metal powder to produce the desired part. In the curing step the powder is heated to dry the binder, creating a green state part that can be carefully handled. Upon removing excess powder the part undergoes infiltration and sintering in a furnace to produce a final dense part.
Students at Lafayette are afforded unique opportunities through the AMI by having access to 3D metal printing technologies where they can explore, learn, and engage in projects that use this technology. Students have engaged in projects that have sough to characterize and understand the thermophysical properties of the binder, the process of printing (interaction between binder/printhead and binder/powder), and the green state part strength.
