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. [...]

Numerical and Experimental Investigation in Replicating a Micro-Featured Surface with the Injection Molding Process

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

This paper describes current efforts to numerically and experimentally investigate micro and nanoscale features replication using the injection molding process. A silicon (Si) insert with micro–features is fabricated via photolithography followed by deep reactive ion [...]
