Robotic Deposition to Enable Multi-Axis Material Extrusion

Kubalak J.R., Williams C.B., Virginia Tech, US

The material extrusion (ME) additive manufacturing process is extensively used in hobbyist and prototyping applications, but it is not always suitable for the fabrication of end-use components. The thermal characteristics of the layer-by-layer deposition results [...]

Metal-Monolithic Ceramic/Metal Composite Castings Produced Using 3D Printed Sand Molds and Cores

Druschitz A.P., Williams C.B., Wood B., Virginia Tech, US

Monolithic ceramic and/or metallic objects can be embedded into metal castings using 3D printed sand mold and core technologies. The resulting composite castings can have a combination of mechanical and/or physical properties that cannot be [...]

Additive Manufacturing (AM) of Quantum Dot Nano-Inks

Ivanova O.S., Elliott A., Campbell T.A., Williams C.B., Virginia Tech, US

Additive Manufacturing (AM) pertains to technologies that fabricate 3D artifacts through the successive addition of 2D cross-sectional layers. Due to this layer-by-layer fabrication process, AM allows a designer to create geometrically complex artifacts with designed [...]
