Drop-on-Demand 3D Metal Printing

Karampelas I.H., Vader S., Vader Z., Vader S., Vader Z., Sukhotskiy V., Verma A., Garg G., Tong M., Furlani E.P., University at Buffalo, US

At present, most 3D metal printing applications involve metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) and Direct Metal Sintering (DMLS) [...]

Additive “4D” Rheoprinting for the Manufacture of Enhanced Biomaterial Products

Duhduh A., Jaafar I.H., Coulter J.P., Lehigh University, US

A novel additive manufacturing technique, which we have coined as the “4D Rheoprinter”, has been developed. This technique enables 3D printing of polymers with tunable material properties for optimized performance in wide range of applications. [...]

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 [...]

Development of a Gold Nanoparticle Conductive Ink with a Relatively Low Sintering Temperature

Hamacher S., Bachmann B., Yakushenko A., Forschungszentrum Jülich, DE

Inkjet printing is a widely used and a well-known technique, which has been recently used for deposition of functional materials, such as conductive inks for the fabrication of low-cost electronic systems. Nowadays, a variety of [...]

Inkjet Printing of High Index Zirconia Nanocomposite Materials

Healy M.D., Guschl P., Wang X., Weinstein M., Pixelligent Technologies LLC, US

Abstract High refractive index (RI) nanocomposites have properties which surpass traditional polymers while maintaining manufacturability. Nanocrystal-polymer nanocomposites, when inkjet-printed, are useful to many display components and aid the development of next generation displays. This paper [...]

Inkjet printing of carbon nanospheres

Orrill M., Abele D., Banek N., Wagner M., LeBlanc S., The George Washington University, US

Proposed applications of drop-on-demand (DOD) inkjet printing extend beyond printing of text and graphics to include rapid manufacturing of thin electrical devices. The most commonly printed electronic materials are silver nanoparticles due to their potentially [...]

One-dimensional simulation of drop breakup in inkjet
